Define your personal ESG priorities and investment objectives
Translate values into specific, actionable investment criteria
Construct a diversified sustainable investment portfolio
Select appropriate ESG funds and investments for your strategy
Implement your sustainable investing plan practically
Balance ESG considerations with financial goals and constraints

9.1 Starting with Self-Assessment

Before You Invest: Know Yourself

Building a sustainable portfolio starts not with choosing investments, but with understanding yourself—your values, goals, constraints, and capabilities.

Step 1: Define Your ESG Priorities

Ask yourself: What matters most to me?

Environmental Priorities:

Climate change mitigation
Renewable energy transition
Biodiversity and nature conservation
Water conservation and quality
Pollution reduction
Circular economy and waste reduction
Sustainable agriculture and food systems

Social Priorities:

Labor rights and fair wages
Workplace safety and health
Diversity, equity, and inclusion
Human rights and supply chain ethics
Community development and economic inclusion
Healthcare access
Education access and quality
Consumer protection and data privacy

Governance Priorities:

Prioritization Exercise: From the items you checked, identify your top 3-5 priorities. These become the core focus of your ESG investment strategy.

Example: "My top priorities are: (1) climate change mitigation, (2) diversity and inclusion, (3) labor rights, (4) board governance quality."

Step 2: Identify Your "Non-Negotiables"

What are you absolutely unwilling to invest in?

Common exclusions:

Fossil fuels (coal, oil, gas)
Tobacco
Weapons and defense
Gambling
Alcohol
Adult entertainment
Private prisons
Companies with serious human rights violations

Your exclusions: _________________________

Important: Be realistic. Excluding too many sectors can severely limit diversification. Consider whether you want zero tolerance or revenue thresholds (e.g., exclude companies with >10% revenue from fossil fuels).

Step 3: Clarify Your Financial Goals

ESG investing must still serve your financial objectives:

Investment Goals:

Time Horizon:

Short-term (< 3 years)
Medium-term (3-10 years)
Long-term (10+ years)

Risk Tolerance:

Conservative (preserve capital, lower volatility)
Moderate (balanced growth and stability)
Aggressive (maximize growth, accept volatility)

Return Expectations:

Market-rate returns (competitive with conventional investing)
Willing to accept somewhat lower returns for greater impact
Below-market returns acceptable if impact is meaningful

Liquidity Needs:

Need regular withdrawals (income portfolio)
May need access to capital (maintain liquidity)
Can lock up capital long-term (access to alternatives)

Step 4: Assess Your Resources and Constraints

Portfolio Size:

Small (< $10,000): Focus on low-cost ETFs, fractional shares
Medium ($10,000-$100,000): Mix of ETFs and mutual funds
Large ($100,000-$1M): Add individual stocks, more alternatives
Very Large (> $1M): Access to separately managed accounts, private investments

Time and Expertise:

Limited time/knowledge: Index funds and simple strategies
Moderate engagement: Mix of passive and active funds
Significant commitment: Individual stock selection, active engagement

Investment Platform:

Retirement accounts (401k, IRA): Limited to plan offerings
Taxable accounts: Full flexibility
Platform constraints: What does your broker offer?

Tax Situation:

Tax-advantaged accounts: Less concern about turnover
Taxable accounts: Consider tax efficiency, hold periods

Step 5: Decision Framework Summary

Complete this framework:

My ESG Priorities: ____________________ My Exclusions: ____________________ My Primary Goal: ____________________ Time Horizon: ____________________ Risk Tolerance: ____________________ Return Expectations: ____________________ Portfolio Size: ____________________ Time/Capability: ____________________

This framework guides all subsequent decisions.

9.2 Translating Values into Investment Criteria

From Abstract Values to Concrete Criteria

Your priorities and exclusions need to become specific, actionable investment criteria.

Creating Your ESG Screening Criteria

Example: Climate Change Priority

Vague: "I want to invest in companies addressing climate change"

Specific Criteria:

Exclude companies with >10% revenue from fossil fuel extraction
Prioritize companies with science-based emissions reduction targets
Favor companies with >50% renewable energy use
Include companies enabling climate solutions (renewable energy, efficiency, EVs)
Require TCFD-aligned climate disclosure

Example: Diversity Priority

Vague: "I want diverse companies"

Specific Criteria:

Require >30% women on board of directors
Prioritize companies with CEO commitment to diversity
Favor companies publishing diversity data and targets
Look for pay equity verification
Include companies with strong diversity ratings (MSCI, Bloomberg)

Your Turn: For each of your top 3-5 priorities, create specific, measurable criteria.

Positive vs. Negative Screens

Decide your approach for each priority:

Negative Screen (Exclusion):

"I will NOT invest in companies that..."
Binary: company is excluded or not
Easier to implement
More restrictive

Positive Screen (Selection):

"I will SEEK companies that..."
Spectrum: degrees of quality
More flexible
Requires ESG assessment capability

Combination (Most common):

Negative screens for non-negotiables
Positive screens for priorities
"Exclude fossil fuels, seek climate leaders in remaining universe"

Setting Thresholds and Standards

For negative screens, define thresholds:

Zero tolerance: Any involvement = exclusion
Revenue threshold: >X% revenue from activity = exclusion
Severity threshold: Serious violations = exclusion, minor issues acceptable

For positive screens, define minimum standards:

Top quartile ESG rating
Specific certifications (B-Corp, Fair Trade, etc.)
Minimum diversity percentages
Required disclosures or commitments

Balance: Stricter criteria = better ESG alignment but less diversification. Find the right balance for your priorities and risk tolerance.

9.3 Portfolio Construction Approaches

Approach 1: Full ESG Integration

Strategy: Apply ESG criteria across entire portfolio

Implementation:

All holdings meet your ESG criteria
No distinction between "ESG" and "non-ESG" portions
Comprehensive approach

Advantages:

Complete values alignment
Simpler portfolio structure
Clear commitment

Disadvantages:

Most restrictive
Potential tracking error vs. broad market
May require more research or higher costs

Best for: Investors with strong ESG commitment willing to accept full integration consequences

Approach 2: Core-Satellite

Strategy: ESG core with thematic satellites

Implementation:

70-80%: Broad ESG index funds (core)
20-30%: Thematic funds matching priorities (satellite)

Example:

70%: ESG total market index fund
15%: Clean energy thematic fund
10%: Gender diversity fund
5%: Impact bond fund

Advantages:

Diversified core reduces risk
Satellites express specific priorities
Flexible and adjustable

Disadvantages:

More complex to manage
Potential overlap between core and satellites
Rebalancing needed

Best for: Investors wanting both broad ESG exposure and specific theme emphasis

Approach 3: Partial ESG Allocation

Strategy: ESG portion of portfolio, conventional portion for other objectives

Implementation:

X% ESG portfolio (meets your criteria)
(100-X)% Conventional portfolio (no ESG criteria)

Example:

60% ESG portfolio
40% Conventional index funds

Advantages:

Ease into ESG investing
Maintain broad market exposure
Lower cost (conventional indexes cheaper)
Can increase ESG allocation over time

Disadvantages:

Partial values alignment
Complexity of managing two strategies
Portfolio will include companies you'd prefer to avoid

Best for: Investors exploring ESG, those with some ESG commitment but prioritizing diversification, or those with mixed accounts (ESG in taxable, conventional in 401k with limited options)

Approach 4: Targeted Impact

Strategy: Specific allocations to high-impact opportunities

Implementation:

Broad conventional or ESG core
Targeted allocations to impact investments

Example:

80% ESG total market portfolio
10% Community development investments
5% Microfinance fund
5% Green bonds

Advantages:

Measurable impact from targeted investments
Maintain diversification in core
Impact where it matters most

Disadvantages:

Impact investments may have lower returns
Some may be illiquid
Requires research into impact opportunities

Best for: Investors seeking measurable impact willing to allocate portion of portfolio to below-market or illiquid investments

Choosing Your Approach

Decision factors:

Choose Full Integration if:

Strong ESG commitment across all investments
ESG is primary consideration alongside returns
Want simplicity and full alignment

Choose Core-Satellite if:

Want broad ESG exposure plus specific themes
Comfortable with some complexity
Have specific priority areas for emphasis

Choose Partial Allocation if:

Exploring ESG, not yet fully committed
Limited ESG options in some accounts (401k)
Prioritize maximum diversification
Want flexibility to adjust ESG % over time

Choose Targeted Impact if:

Want measurable impact alongside returns
Willing to accept some below-market returns
Have capital available for illiquid investments

9.4 Asset Allocation with ESG

ESG Across Asset Classes

A complete portfolio includes multiple asset classes. ESG considerations apply to each:

Equities (Stocks)

Options:

ESG index funds/ETFs (US and international)
Actively managed ESG funds
Thematic equity funds
Individual ESG-selected stocks (if sufficient portfolio size and capability)

Allocation Considerations:

Domestic vs. international
Large-cap vs. small-cap
Growth vs. value
Sector exposures (affected by ESG exclusions)

ESG Availability: Excellent—many options across all equity categories

Fixed Income (Bonds)

Options:

ESG-integrated bond funds
Green bonds and green bond funds
Social and sustainability bonds
Impact bonds (community development, microfinance)
Individual bonds (if portfolio size sufficient)

Allocation Considerations:

Government vs. corporate
Investment-grade vs. high-yield
Duration and interest rate sensitivity
Credit quality

ESG Availability: Good and growing—green bond market expanding, ESG corporate bond funds available

Real Estate

Options:

Green building REITs
Affordable housing REITs
ESG-focused real estate funds
Direct real estate (green buildings, community development)

Allocation Considerations:

Real estate as inflation hedge
Income generation
Geographic and property type diversification

ESG Availability: Moderate—some ESG REIT options, more in private real estate

Alternatives

Options:

Private equity impact funds
Venture capital climate/impact funds
Sustainable infrastructure funds
Farmland and timberland (sustainable)

Allocation Considerations:

Illiquidity (long lockup periods)
Higher minimums (often accredited investors only)
Diversification and risk management

ESG Availability: Growing but limited to larger investors; high due diligence required

Sample Asset Allocations with ESG

Conservative ESG Portfolio (60/40):

30% ESG US equity index fund
15% ESG international equity fund
15% ESG emerging markets equity fund
30% ESG bond fund
10% Green bonds

Moderate ESG Portfolio (70/30):

35% ESG US equity index fund
20% ESG international equity fund
15% Clean energy thematic fund
20% ESG bond fund
10% Impact investments (community development, microfinance)

Aggressive ESG Portfolio (90/10):

45% ESG US equity index fund
25% ESG international equity fund
15% Clean energy and sustainable agriculture thematic funds
5% ESG bond fund
5% Impact investments
5% Sustainable real estate or infrastructure

Adjust percentages based on your risk tolerance, time horizon, and specific priorities.

9.5 Selecting Specific Investments

Step-by-Step Fund Selection Process

Step 1: Identify Fund Category Need Based on your target allocation, what type of fund do you need? (e.g., "ESG US large-cap equity index fund")

Step 2: Screen for Availability What funds in this category are available through your investment platform?

Step 3: Apply ESG Criteria Which funds meet your ESG priorities and exclusions?

Review prospectus methodology
Check holdings alignment
Verify ESG research approach

Step 4: Evaluate Quality

ESG rating/recognition
Track record length
Management team
Third-party ESG research used

Step 5: Compare Costs

Expense ratios
Transaction costs
Tax efficiency

Step 6: Assess Performance

Returns vs. benchmark over 3-5+ years
Risk-adjusted performance
Volatility and drawdowns

Step 7: Check Diversification

Number of holdings
Concentration risks
Sector allocations
Geographic exposures

Step 8: Make Selection Choose fund that best balances ESG quality, costs, performance, and diversification

Example Fund Selection

Need: ESG US large-cap equity fund

Available Options (examples):

Vanguard ESG US Stock ETF (ESGV) - 0.09% expense ratio
iShares MSCI USA ESG Select ETF (SUSA) - 0.25% expense ratio
Parnassus Core Equity Fund (PRBLX) - 0.82% expense ratio

ESG Evaluation:

ESGV: Broad ESG screening, excludes controversial sectors, 1,400+ holdings
SUSA: MSCI ESG ratings-based, best-in-class approach, 180+ holdings
PRBLX: Active management, deep ESG research, engagement, 40-50 holdings

Cost Comparison:

ESGV: Lowest cost, passive
SUSA: Moderate cost, passive
PRBLX: Highest cost, active management

Performance (hypothetical):

All three have performed similarly over 5 years
PRBLX has somewhat higher volatility due to concentration
ESGV tracks ESG index most closely

Selection Decision:

Choose ESGV if: Prioritize low cost, broad diversification, passive approach
Choose SUSA if: Want more selective ESG, moderate concentration, still passive
Choose PRBLX if: Value active management and engagement, willing to pay for it

There's no single "right" answer—depends on your priorities and preferences.

Building Your Fund List

Create a target fund list for your portfolio:

Asset Class	Fund Category	Selected Fund	Allocation %
US Equity	ESG Large-Cap	[Fund name]	[%]
International Equity	ESG International	[Fund name]	[%]
Bonds	ESG Bond	[Fund name]	[%]
Thematic	Clean Energy	[Fund name]	[%]
Impact	Community Development	[Fund name]	[%]

Total: 100%

9.6 Implementation: Getting Started

Step 1: Inventory Current Holdings

List all current investments:

What funds/stocks do you currently own?
What are their ESG characteristics?
Which meet your new criteria? Which don't?

Evaluate:

Keep (meets ESG criteria)
Replace (doesn't meet criteria)
Hold temporarily (transition gradually)

Step 2: Plan Your Transition

Option A: Immediate Full Transition

Sell all non-conforming holdings
Buy ESG portfolio immediately

Pros: Immediate values alignment Cons: Potential tax consequences, transaction costs, market timing risk

Option B: Gradual Transition

Transition over 6-12 months
Sell and replace in stages
New money goes to ESG investments

Pros: Spreads market timing risk, manages tax impact Cons: Temporary misalignment with values

Option C: Natural Transition

Keep existing holdings
All new investments in ESG funds
Sell holdings only as needed or beneficial (rebalancing, tax-loss harvesting)

Pros: Minimal transaction costs and taxes Cons: Slowest alignment, portfolio remains mixed longer

Tax Considerations:

Capital gains in taxable accounts
Tax-loss harvesting opportunities
No tax consequences in retirement accounts (IRA, 401k)

Most investors choose Option B or C to manage costs and taxes while progressing toward goals.

Step 3: Initial Purchases

Execute your plan:

Fund your account
Place initial trades according to target allocation
Document your rationale and criteria

Start small if uncertain:

Begin with core holdings (broad ESG index funds)
Add satellites and thematic investments as you gain confidence
Can always increase ESG allocation over time

Step 4: Document Your Strategy

Create an Investment Policy Statement (IPS) for your ESG portfolio:

Sample ESG Investment Policy Statement:

ESG Investment Policy Statement

Goals: [Your financial goals]

ESG Priorities: [Your top 3-5 ESG priorities]

Exclusions: [What you won't invest in]

Strategy: [Your chosen approach—full integration, core-satellite, etc.]

Target Allocation:

etc.

Rebalancing: [When and how you'll rebalance—e.g., annually, when allocation drifts >5%]

Review Schedule: [How often you'll review—e.g., quarterly, annually]

ESG Criteria: [Your specific ESG selection criteria]

Monitoring: [What you'll track—performance, ESG ratings, controversies]

Having a written IPS provides:

Clarity on strategy
Discipline during market volatility
Reference point for decisions
Documentation for yourself (or advisor)

9.7 Ongoing Management and Monitoring

Regular Portfolio Review

Quarterly Reviews (quick check):

Performance vs. benchmarks
Allocation drift (need to rebalance?)
Any major ESG controversies in holdings?
New ESG news or developments

Annual Reviews (comprehensive):

Full performance evaluation
ESG fund quality assessment
Criteria review (do your priorities still align?)
Tax-loss harvesting opportunities
Rebalancing to target allocation

Performance Monitoring

Track multiple metrics:

Financial Performance:

Absolute returns
Returns vs. relevant benchmarks
Risk-adjusted returns (Sharpe ratio)
Volatility and maximum drawdown

ESG Performance:

Portfolio ESG ratings (if available)
Carbon footprint trends
Alignment with priorities
Improvements or deterioration

Don't overreact to short-term performance: ESG benefits often accrue over 3-5+ years, not quarter to quarter.

Rebalancing

When to rebalance:

Annual rebalancing (systematic)
When allocation drifts >5-10% from target (threshold-based)
Opportunistic (market events create opportunities)

How to rebalance:

Sell overweight positions, buy underweight
Direct new contributions to underweight positions
Tax-loss harvest in taxable accounts

Rebalancing with ESG considerations:

Maintain ESG criteria during rebalancing
Don't rebalance into non-ESG holdings
Use rebalancing as opportunity to upgrade to better ESG funds if available

Monitoring ESG Quality

Stay informed about your holdings:

Read annual ESG reports from funds
Check for ESG rating changes
Monitor for greenwashing controversies
Track fund methodology changes

Be willing to upgrade:

If better ESG fund becomes available, consider switching
If fund's ESG quality deteriorates, replace it
If your criteria evolve, adjust holdings accordingly

Dealing with Controversies

What to do when a holding faces ESG controversy:

Step 1: Assess Severity

How serious is the issue?
Is it isolated incident or systemic problem?
Does it violate your core criteria?

Step 2: Evaluate Response

How is the company/fund responding?
Are they addressing the issue or deflecting?
What remediation plans exist?

Step 3: Decide

Keep: If minor issue or company responding well
Monitor: If serious but response is promising
Sell: If severe violation or inadequate response

Step 4: Document

Record your decision and reasoning
Learn from the experience
Update criteria if needed

Adapting to Change

Your ESG portfolio should evolve as:

Your circumstances change:

Life stage transitions
Risk tolerance shifts
Financial goals adjust
Knowledge and sophistication grow

ESG landscape evolves:

Better products become available
Standards improve
Regulations change
Your understanding deepens

Markets shift:

New opportunities emerge
Risks materialize or fade
Performance diverges from expectations

Stay flexible while maintaining core commitments.

9.8 Common Challenges and Solutions

Challenge 1: Limited Options in 401(k)

Problem: Your workplace retirement plan has no or poor ESG options.

Solutions:

Advocate for ESG options (talk to HR, submit requests)
Choose best available options (highest ESG-rated conventional funds)
Implement ESG strategy in IRA or taxable accounts
Consider if contribution amount justifies accepting conventional funds for tax benefits
When changing jobs, roll over to IRA with full ESG options

Challenge 2: Underperformance Anxiety

Problem: Your ESG portfolio underperforms conventional benchmarks short-term.

Solutions:

Review time horizon (is this short-term noise or long-term problem?)
Check if underperformance is due to ESG or other factors (active management, sector tilts)
Remember why you chose ESG investing (values alignment, long-term risk management)
Evaluate whether fees are justified
Consider if you need to adjust strategy (more indexing, less thematic concentration)

Challenge 3: Information Overload

Problem: Too much ESG data, ratings, and information to process.

Solutions:

Focus on material issues for each investment (use SASB)
Don't try to analyze everything—use trusted third-party research
Simplify with index funds (outsource ESG selection)
Create checklist of must-have criteria (ignore the rest)
Remember: good enough is better than perfect paralysis

Challenge 4: Values Conflicts

Problem: Different ESG priorities conflict (e.g., climate vs. jobs in fossil fuel regions).

Solutions:

Acknowledge complexity and trade-offs
Prioritize (rank your values)
Accept imperfect solutions
Consider "just transition" approaches (support workers while transitioning industries)
Engage rather than simply exclude when possible

Challenge 5: Family/Partner Disagreement

Problem: You and partner/family disagree on ESG approach.

Solutions:

Discuss values and find common ground
Each manage portion of portfolio according to preferences
Agree on minimum standards everyone accepts
Focus on shared priorities
Seek compromise (partial ESG allocation everyone can support)

Challenge 6: Keeping Up with Changes

Problem: ESG landscape evolves rapidly—hard to stay current.

Solutions:

Set regular review schedule (don't need constant monitoring)
Follow a few trusted ESG information sources
Join ESG investing community or forum
Consider working with ESG-knowledgeable advisor
Remember: consistency over time matters more than chasing every new development

9.9 Working with Financial Advisors

When to Consider an Advisor

You might benefit from professional help if:

Portfolio is large and complex
You lack time for ongoing management
You want specialized ESG expertise
You need comprehensive financial planning
You have complex tax situations
You want accountability and discipline

Finding an ESG-Knowledgeable Advisor

Look for:

Advisors with ESG/sustainable investing specialization
Certifications: FSA (Fundamentals of Sustainability Accounting), CFSA (Chartered Financial Services Auditor with ESG focus)
Experience implementing ESG strategies
Access to ESG research and tools
Understanding of your values and priorities

Questions to ask:

How do you incorporate ESG into investment recommendations?
What ESG research and tools do you use?
What percentage of your clients use ESG strategies?
Can you show examples of ESG portfolios you've built?
How do you measure ESG portfolio characteristics?
What's your philosophy on ESG investing?

Red flags:

Dismissive of ESG investing
No ESG knowledge or experience
Claims ESG always underperforms (or always outperforms)
Can't articulate ESG approach clearly
Only offers proprietary products with high fees

Working Effectively with Your Advisor

Communicate clearly:

Share your ESG priorities and exclusions
Explain your financial goals and constraints
Be clear about how much you're willing to compromise

Ask questions:

Why this fund over alternatives?
How does this align with my ESG criteria?
What are the trade-offs?

Review regularly:

Ensure portfolio remains aligned with your goals
Verify ESG quality is maintained
Understand any changes recommended

Remember: You're the client. Advisor should serve your goals, not impose their views.

Module 9 Summary

Let's consolidate your learning on building a sustainable portfolio:

Self-Assessment First: Define ESG priorities, exclusions, financial goals, risk tolerance, and constraints before selecting investments.

Translate Values to Criteria: Convert abstract priorities into specific, measurable investment criteria and screening rules.

Choose an Approach: Full integration, core-satellite, partial allocation, or targeted impact—select structure matching your goals and circumstances.

Asset Allocation: Apply ESG across all asset classes (stocks, bonds, real estate, alternatives) maintaining appropriate diversification for risk level.

Fund Selection: Systematic process evaluating ESG quality, costs, performance, and diversification for each portfolio position.

Implementation: Plan transition considering taxes and costs; create Investment Policy Statement documenting strategy.

Ongoing Management: Regular reviews of performance and ESG quality; disciplined rebalancing; monitoring for controversies; willingness to upgrade holdings.

Common Challenges: Limited 401(k) options, underperformance anxiety, information overload, values conflicts—all solvable with appropriate strategies.

Professional Help: Consider ESG-knowledgeable advisor if portfolio complexity, time constraints, or expertise gaps warrant it.

Key Insight: Building a sustainable portfolio is personal—your values, goals, and circumstances drive decisions. There's no single "correct" ESG portfolio, only the right one for you. Start with clarity on priorities, implement systematically, and manage patiently over time.

You now have the complete framework to build and manage your actual sustainable investment portfolio. The final modules will provide advanced perspectives, address the future of ESG investing, and consolidate everything you've learned.

Test your understanding:

What are the key elements of self-assessment before building an ESG portfolio?
How do you translate an abstract ESG priority (like "climate change") into specific investment criteria?
What's the difference between full ESG integration and a core-satellite approach? When might you choose each?
How should you apply ESG considerations across different asset classes in your portfolio?
What are the key steps in selecting a specific ESG fund?
What are the three main options for transitioning from a conventional to an ESG portfolio, and what are the trade-offs?
What should you monitor in your ESG portfolio beyond just financial returns?

Reflection Questions:

Based on your self-assessment, which portfolio construction approach would be most appropriate for you?
What would be your top 3 ESG priorities, and how would you translate them into investment criteria?

9.1 Starting with Self-Assessment

Before You Invest: Know Yourself

Building a sustainable portfolio starts not with choosing investments, but with understanding yourself—your values, goals, constraints, and capabilities.

Step 1: Define Your ESG Priorities

Ask yourself: What matters most to me?

Environmental Priorities:

Climate change mitigation
Renewable energy transition
Biodiversity and nature conservation
Water conservation and quality
Pollution reduction
Circular economy and waste reduction
Sustainable agriculture and food systems

Social Priorities:

Labor rights and fair wages
Workplace safety and health
Diversity, equity, and inclusion
Human rights and supply chain ethics
Community development and economic inclusion
Healthcare access
Education access and quality
Consumer protection and data privacy

Governance Priorities:

Prioritization Exercise: From the items you checked, identify your top 3-5 priorities. These become the core focus of your ESG investment strategy.

Example: "My top priorities are: (1) climate change mitigation, (2) diversity and inclusion, (3) labor rights, (4) board governance quality."

Step 2: Identify Your "Non-Negotiables"

What are you absolutely unwilling to invest in?

Common exclusions:

Fossil fuels (coal, oil, gas)
Tobacco
Weapons and defense
Gambling
Alcohol
Adult entertainment
Private prisons
Companies with serious human rights violations

Your exclusions: _________________________

Step 3: Clarify Your Financial Goals

ESG investing must still serve your financial objectives:

Investment Goals:

Time Horizon:

Short-term (< 3 years)
Medium-term (3-10 years)
Long-term (10+ years)

Risk Tolerance:

Conservative (preserve capital, lower volatility)
Moderate (balanced growth and stability)
Aggressive (maximize growth, accept volatility)

Return Expectations:

Market-rate returns (competitive with conventional investing)
Willing to accept somewhat lower returns for greater impact
Below-market returns acceptable if impact is meaningful

Liquidity Needs:

Need regular withdrawals (income portfolio)
May need access to capital (maintain liquidity)
Can lock up capital long-term (access to alternatives)

Step 4: Assess Your Resources and Constraints

Portfolio Size:

Small (< $10,000): Focus on low-cost ETFs, fractional shares
Medium ($10,000-$100,000): Mix of ETFs and mutual funds
Large ($100,000-$1M): Add individual stocks, more alternatives
Very Large (> $1M): Access to separately managed accounts, private investments

Time and Expertise:

Limited time/knowledge: Index funds and simple strategies
Moderate engagement: Mix of passive and active funds
Significant commitment: Individual stock selection, active engagement

Investment Platform:

Retirement accounts (401k, IRA): Limited to plan offerings
Taxable accounts: Full flexibility
Platform constraints: What does your broker offer?

Tax Situation:

Tax-advantaged accounts: Less concern about turnover
Taxable accounts: Consider tax efficiency, hold periods

Step 5: Decision Framework Summary

Complete this framework:

This framework guides all subsequent decisions.

9.2 Translating Values into Investment Criteria

From Abstract Values to Concrete Criteria

Your priorities and exclusions need to become specific, actionable investment criteria.

Creating Your ESG Screening Criteria

Example: Climate Change Priority

Vague: "I want to invest in companies addressing climate change"

Specific Criteria:

Exclude companies with >10% revenue from fossil fuel extraction
Prioritize companies with science-based emissions reduction targets
Favor companies with >50% renewable energy use
Include companies enabling climate solutions (renewable energy, efficiency, EVs)
Require TCFD-aligned climate disclosure

Example: Diversity Priority

Vague: "I want diverse companies"

Specific Criteria:

Require >30% women on board of directors
Prioritize companies with CEO commitment to diversity
Favor companies publishing diversity data and targets
Look for pay equity verification
Include companies with strong diversity ratings (MSCI, Bloomberg)

Your Turn: For each of your top 3-5 priorities, create specific, measurable criteria.

Positive vs. Negative Screens

Decide your approach for each priority:

Negative Screen (Exclusion):

"I will NOT invest in companies that..."
Binary: company is excluded or not
Easier to implement
More restrictive

Positive Screen (Selection):

"I will SEEK companies that..."
Spectrum: degrees of quality
More flexible
Requires ESG assessment capability

Combination (Most common):

Negative screens for non-negotiables
Positive screens for priorities
"Exclude fossil fuels, seek climate leaders in remaining universe"

Setting Thresholds and Standards

For negative screens, define thresholds:

Zero tolerance: Any involvement = exclusion
Revenue threshold: >X% revenue from activity = exclusion
Severity threshold: Serious violations = exclusion, minor issues acceptable

For positive screens, define minimum standards:

Top quartile ESG rating
Specific certifications (B-Corp, Fair Trade, etc.)
Minimum diversity percentages
Required disclosures or commitments

Balance: Stricter criteria = better ESG alignment but less diversification. Find the right balance for your priorities and risk tolerance.

9.3 Portfolio Construction Approaches

Approach 1: Full ESG Integration

Strategy: Apply ESG criteria across entire portfolio

Implementation:

All holdings meet your ESG criteria
No distinction between "ESG" and "non-ESG" portions
Comprehensive approach

Advantages:

Complete values alignment
Simpler portfolio structure
Clear commitment

Disadvantages:

Most restrictive
Potential tracking error vs. broad market
May require more research or higher costs

Best for: Investors with strong ESG commitment willing to accept full integration consequences

Approach 2: Core-Satellite

Strategy: ESG core with thematic satellites

Implementation:

70-80%: Broad ESG index funds (core)
20-30%: Thematic funds matching priorities (satellite)

Example:

70%: ESG total market index fund
15%: Clean energy thematic fund
10%: Gender diversity fund
5%: Impact bond fund

Advantages:

Diversified core reduces risk
Satellites express specific priorities
Flexible and adjustable

Disadvantages:

More complex to manage
Potential overlap between core and satellites
Rebalancing needed

Best for: Investors wanting both broad ESG exposure and specific theme emphasis

Approach 3: Partial ESG Allocation

Strategy: ESG portion of portfolio, conventional portion for other objectives

Implementation:

X% ESG portfolio (meets your criteria)
(100-X)% Conventional portfolio (no ESG criteria)

Example:

60% ESG portfolio
40% Conventional index funds

Advantages:

Ease into ESG investing
Maintain broad market exposure
Lower cost (conventional indexes cheaper)
Can increase ESG allocation over time

Disadvantages:

Partial values alignment
Complexity of managing two strategies
Portfolio will include companies you'd prefer to avoid

Best for: Investors exploring ESG, those with some ESG commitment but prioritizing diversification, or those with mixed accounts (ESG in taxable, conventional in 401k with limited options)

Approach 4: Targeted Impact

Strategy: Specific allocations to high-impact opportunities

Implementation:

Broad conventional or ESG core
Targeted allocations to impact investments

Example:

80% ESG total market portfolio
10% Community development investments
5% Microfinance fund
5% Green bonds

Advantages:

Measurable impact from targeted investments
Maintain diversification in core
Impact where it matters most

Disadvantages:

Impact investments may have lower returns
Some may be illiquid
Requires research into impact opportunities

Best for: Investors seeking measurable impact willing to allocate portion of portfolio to below-market or illiquid investments

Choosing Your Approach

Willing to accept some below-market returns
Have capital available for illiquid investments

9.4 Asset Allocation with ESG

ESG Across Asset Classes

A complete portfolio includes multiple asset classes. ESG considerations apply to each:

Equities (Stocks)

Options:

Adjust percentages based on your risk tolerance, time horizon, and specific priorities.

9.5 Selecting Specific Investments

Step-by-Step Fund Selection Process

Step 1: Identify Fund Category Need Based on your target allocation, what type of fund do you need? (e.g., "ESG US large-cap equity index fund")

Step 2: Screen for Availability What funds in this category are available through your investment platform?

Step 3: Apply ESG Criteria Which funds meet your ESG priorities and exclusions?

Review prospectus methodology
Check holdings alignment
Verify ESG research approach

Step 4: Evaluate Quality

ESG rating/recognition
Track record length
Management team
Third-party ESG research used

Step 5: Compare Costs

Expense ratios
Transaction costs
Tax efficiency

Step 6: Assess Performance

Returns vs. benchmark over 3-5+ years
Risk-adjusted performance
Volatility and drawdowns

Step 7: Check Diversification

Number of holdings
Concentration risks
Sector allocations
Geographic exposures

Step 8: Make Selection Choose fund that best balances ESG quality, costs, performance, and diversification

Example Fund Selection

Need: ESG US large-cap equity fund

Available Options (examples):

Vanguard ESG US Stock ETF (ESGV) - 0.09% expense ratio
iShares MSCI USA ESG Select ETF (SUSA) - 0.25% expense ratio
Parnassus Core Equity Fund (PRBLX) - 0.82% expense ratio

ESG Evaluation:

ESGV: Broad ESG screening, excludes controversial sectors, 1,400+ holdings
SUSA: MSCI ESG ratings-based, best-in-class approach, 180+ holdings
PRBLX: Active management, deep ESG research, engagement, 40-50 holdings

Cost Comparison:

ESGV: Lowest cost, passive
SUSA: Moderate cost, passive
PRBLX: Highest cost, active management

Performance (hypothetical):

All three have performed similarly over 5 years
PRBLX has somewhat higher volatility due to concentration
ESGV tracks ESG index most closely

Selection Decision:

Choose ESGV if: Prioritize low cost, broad diversification, passive approach
Choose SUSA if: Want more selective ESG, moderate concentration, still passive
Choose PRBLX if: Value active management and engagement, willing to pay for it

There's no single "right" answer—depends on your priorities and preferences.

Building Your Fund List

Create a target fund list for your portfolio:

Asset Class	Fund Category	Selected Fund	Allocation %
US Equity	ESG Large-Cap	[Fund name]	[%]
International Equity	ESG International	[Fund name]	[%]
Bonds	ESG Bond	[Fund name]	[%]
Thematic	Clean Energy	[Fund name]	[%]
Impact	Community Development	[Fund name]	[%]

Total: 100%

9.6 Implementation: Getting Started

Step 1: Inventory Current Holdings

List all current investments:

What funds/stocks do you currently own?
What are their ESG characteristics?
Which meet your new criteria? Which don't?

Evaluate:

Keep (meets ESG criteria)
Replace (doesn't meet criteria)
Hold temporarily (transition gradually)

Step 2: Plan Your Transition

Option A: Immediate Full Transition

Sell all non-conforming holdings
Buy ESG portfolio immediately

Pros: Immediate values alignment Cons: Potential tax consequences, transaction costs, market timing risk

Option B: Gradual Transition

Transition over 6-12 months
Sell and replace in stages
New money goes to ESG investments

Pros: Spreads market timing risk, manages tax impact Cons: Temporary misalignment with values

Option C: Natural Transition

Keep existing holdings
All new investments in ESG funds
Sell holdings only as needed or beneficial (rebalancing, tax-loss harvesting)

Pros: Minimal transaction costs and taxes Cons: Slowest alignment, portfolio remains mixed longer

Tax Considerations:

Capital gains in taxable accounts
Tax-loss harvesting opportunities
No tax consequences in retirement accounts (IRA, 401k)

Most investors choose Option B or C to manage costs and taxes while progressing toward goals.

Step 3: Initial Purchases

Execute your plan:

Fund your account
Place initial trades according to target allocation
Document your rationale and criteria

Start small if uncertain:

Begin with core holdings (broad ESG index funds)
Add satellites and thematic investments as you gain confidence
Can always increase ESG allocation over time

Step 4: Document Your Strategy

Create an Investment Policy Statement (IPS) for your ESG portfolio:

Sample ESG Investment Policy Statement:

ESG Investment Policy Statement

Goals: [Your financial goals]

ESG Priorities: [Your top 3-5 ESG priorities]

Exclusions: [What you won't invest in]

Strategy: [Your chosen approach—full integration, core-satellite, etc.]

Target Allocation:

etc.

Rebalancing: [When and how you'll rebalance—e.g., annually, when allocation drifts >5%]

Review Schedule: [How often you'll review—e.g., quarterly, annually]

ESG Criteria: [Your specific ESG selection criteria]

Monitoring: [What you'll track—performance, ESG ratings, controversies]

Having a written IPS provides:

Clarity on strategy
Discipline during market volatility
Reference point for decisions
Documentation for yourself (or advisor)

9.7 Ongoing Management and Monitoring

Regular Portfolio Review

Quarterly Reviews (quick check):

Performance vs. benchmarks
Allocation drift (need to rebalance?)
Any major ESG controversies in holdings?
New ESG news or developments

Annual Reviews (comprehensive):

Full performance evaluation
ESG fund quality assessment
Criteria review (do your priorities still align?)
Tax-loss harvesting opportunities
Rebalancing to target allocation

Performance Monitoring

Track multiple metrics:

Financial Performance:

Absolute returns
Returns vs. relevant benchmarks
Risk-adjusted returns (Sharpe ratio)
Volatility and maximum drawdown

ESG Performance:

Portfolio ESG ratings (if available)
Carbon footprint trends
Alignment with priorities
Improvements or deterioration

Don't overreact to short-term performance: ESG benefits often accrue over 3-5+ years, not quarter to quarter.

Rebalancing

When to rebalance:

Annual rebalancing (systematic)
When allocation drifts >5-10% from target (threshold-based)
Opportunistic (market events create opportunities)

How to rebalance:

Sell overweight positions, buy underweight
Direct new contributions to underweight positions
Tax-loss harvest in taxable accounts

Rebalancing with ESG considerations:

Maintain ESG criteria during rebalancing
Don't rebalance into non-ESG holdings
Use rebalancing as opportunity to upgrade to better ESG funds if available

Monitoring ESG Quality

Stay informed about your holdings:

Read annual ESG reports from funds
Check for ESG rating changes
Monitor for greenwashing controversies
Track fund methodology changes

Be willing to upgrade:

If better ESG fund becomes available, consider switching
If fund's ESG quality deteriorates, replace it
If your criteria evolve, adjust holdings accordingly

Dealing with Controversies

What to do when a holding faces ESG controversy:

Step 1: Assess Severity

How serious is the issue?
Is it isolated incident or systemic problem?
Does it violate your core criteria?

Step 2: Evaluate Response

How is the company/fund responding?
Are they addressing the issue or deflecting?
What remediation plans exist?

Step 3: Decide

Keep: If minor issue or company responding well
Monitor: If serious but response is promising
Sell: If severe violation or inadequate response

Step 4: Document

Record your decision and reasoning
Learn from the experience
Update criteria if needed

Adapting to Change

Your ESG portfolio should evolve as:

Your circumstances change:

Life stage transitions
Risk tolerance shifts
Financial goals adjust
Knowledge and sophistication grow

ESG landscape evolves:

Better products become available
Standards improve
Regulations change
Your understanding deepens

Markets shift:

New opportunities emerge
Risks materialize or fade
Performance diverges from expectations

Stay flexible while maintaining core commitments.

9.8 Common Challenges and Solutions

Challenge 1: Limited Options in 401(k)

Problem: Your workplace retirement plan has no or poor ESG options.

Solutions:

Advocate for ESG options (talk to HR, submit requests)
Choose best available options (highest ESG-rated conventional funds)
Implement ESG strategy in IRA or taxable accounts
Consider if contribution amount justifies accepting conventional funds for tax benefits
When changing jobs, roll over to IRA with full ESG options

Challenge 2: Underperformance Anxiety

Problem: Your ESG portfolio underperforms conventional benchmarks short-term.

Solutions:

Review time horizon (is this short-term noise or long-term problem?)
Check if underperformance is due to ESG or other factors (active management, sector tilts)
Remember why you chose ESG investing (values alignment, long-term risk management)
Evaluate whether fees are justified
Consider if you need to adjust strategy (more indexing, less thematic concentration)

Challenge 3: Information Overload

Problem: Too much ESG data, ratings, and information to process.

Solutions:

Focus on material issues for each investment (use SASB)
Don't try to analyze everything—use trusted third-party research
Simplify with index funds (outsource ESG selection)
Create checklist of must-have criteria (ignore the rest)
Remember: good enough is better than perfect paralysis

Challenge 4: Values Conflicts

Problem: Different ESG priorities conflict (e.g., climate vs. jobs in fossil fuel regions).

Solutions:

Acknowledge complexity and trade-offs
Prioritize (rank your values)
Accept imperfect solutions
Consider "just transition" approaches (support workers while transitioning industries)
Engage rather than simply exclude when possible

Challenge 5: Family/Partner Disagreement

Problem: You and partner/family disagree on ESG approach.

Solutions:

Discuss values and find common ground
Each manage portion of portfolio according to preferences
Agree on minimum standards everyone accepts
Focus on shared priorities
Seek compromise (partial ESG allocation everyone can support)

Challenge 6: Keeping Up with Changes

Problem: ESG landscape evolves rapidly—hard to stay current.

Solutions:

Set regular review schedule (don't need constant monitoring)
Follow a few trusted ESG information sources
Join ESG investing community or forum
Consider working with ESG-knowledgeable advisor
Remember: consistency over time matters more than chasing every new development

9.9 Working with Financial Advisors

When to Consider an Advisor

You might benefit from professional help if:

Portfolio is large and complex
You lack time for ongoing management
You want specialized ESG expertise
You need comprehensive financial planning
You have complex tax situations

Ask questions:

Why this fund over alternatives?
How does this align with my ESG criteria?
What are the trade-offs?

Review regularly:

Ensure portfolio remains aligned with your goals
Verify ESG quality is maintained
Understand any changes recommended
