Impact Investing and Measurement

Module 6: Impact Investing and Measurement

Defining Impact Investing

Impact investing refers to investments made with the explicit intention to generate positive, measurable social or environmental impact alongside financial returns.

This distinguishes impact investing from:

• Traditional investing: Focused primarily on financial returns
• ESG investing: Integrates environmental, social, and governance factors into analysis but may not require intentional impact
• Philanthropy: Seeks impact without expectation of financial return

Impact investing occupies a spectrum from "finance-first" (competitive returns with impact) to "impact-first" (accepting below-market returns for greater impact).

The Impact Investing Market

Impact investing has grown from a niche concept to a significant market:

• Over $1 trillion in impact investing assets under management
• Investors range from development finance institutions to family offices to mainstream asset managers
• Investments span asset classes: private equity, debt, real assets, public equities

Growth is driven by increasing investor interest in aligning investments with values, the demonstrated viability of impact strategies, and growing evidence that impact and returns can coexist.

Impact Investing Principles

The Global Impact Investing Network (GIIN) established core principles:

1. Intentionality

The investor explicitly intends to contribute to positive social or environmental outcomes. Impact is not accidental but a deliberate objective.

2. Investment with Return Expectations

The investor expects to generate financial return on capital or, at minimum, return of capital. This distinguishes impact investing from philanthropy.

3. Range of Return Expectations and Asset Classes

Impact investments target financial returns that range from below-market to risk-adjusted market rate, across asset classes.

4. Impact Measurement

A hallmark of impact investing is the commitment to measure and report the social and environmental performance of investments.

Impact Measurement Frameworks

Theory of Change

A theory of change maps how an investment or intervention leads to impact:

Inputs → Activities → Outputs → Outcomes → Impact

Example for a solar energy investment:

• Inputs: Capital invested
• Activities: Solar panel installation
• Outputs: MW of capacity installed
• Outcomes: Clean electricity generated, fossil fuels displaced
• Impact: CO2 emissions avoided, climate change mitigated

IRIS+ System

The IRIS+ system, managed by GIIN, provides:

• Standardized impact metrics
• Core metrics sets by theme and sector
• Alignment with SDGs and other frameworks

Categories include:

• Energy access
• Climate change mitigation
• Water, sanitation, and hygiene
• Food security
• Housing
• Health
• Education
• Financial inclusion

Impact Management Project (IMP) Framework

The IMP developed a framework organized around five dimensions of impact:

1. What: What outcomes occur?
2. Who: Who experiences the outcome?
3. How Much: How significant is the outcome?
4. Contribution: What is the investor's contribution?
5. Risk: What is the risk of impact not occurring?

This framework helps investors understand and compare different types of impact.

UN Sustainable Development Goals (SDGs)

The 17 SDGs provide a common language for impact:

1. No Poverty
2. Zero Hunger
3. Good Health and Well-Being
4. Quality Education
5. Gender Equality
6. Clean Water and Sanitation
7. Affordable and Clean Energy
8. Decent Work and Economic Growth
9. Industry, Innovation and Infrastructure
10. Reduced Inequalities
11. Sustainable Cities and Communities
12. Responsible Consumption and Production
13. Climate Action
14. Life Below Water
15. Life on Land
16. Peace, Justice and Strong Institutions
17. Partnerships for the Goals

Many impact investors map their investments to SDG contributions.

Environmental Impact Metrics

Common environmental impact metrics include:

Climate

• Tonnes of CO2 equivalent avoided/reduced
• Carbon intensity (tCO2e per unit)
• Renewable energy generated (MWh)
• Energy efficiency improvements (%)

Water

• Water saved/treated (cubic meters)
• Water quality improvement
• Access to clean water (people served)

Waste and Circular Economy

• Waste diverted from landfill (tonnes)
• Materials recycled/reused (tonnes)
• Plastic pollution avoided

Biodiversity

• Hectares of land protected/restored
• Species protected
• Ecosystem services preserved

Pollution

• Air pollutants reduced
• Chemical use avoided
• Contamination remediated

The Challenge of Additionality

A key question in impact measurement is additionality: Did the investment create impact that wouldn't have occurred otherwise?

Types of Additionality

Financial Additionality: The investment provided capital that wouldn't be available from other sources, enabling the activity to occur.

Investor Additionality: The investor's non-financial contributions (expertise, networks, engagement) enhanced impact beyond what capital alone would achieve.

Market Additionality: The investment helped develop markets or demonstrate viability, enabling future investments by others.

Assessing Additionality

Questions to consider:

• Would the project have been funded without this investment?
• Would it have been funded on the same terms?
• Did investor involvement improve outcomes?
• Did the investment create demonstration effects?

Impact Verification

Third-party verification strengthens impact claims:

Verification Approaches

• External audits of impact data
• Certification by standard bodies
• Independent evaluation of outcomes
• Site visits and stakeholder interviews

Verification Standards

• B Corp certification (for companies)
• Impact Management Project verification
• GIIN's Compass methodology
• Custom verification frameworks

Avoiding Impact Washing

"Impact washing" is similar to greenwashing—claiming greater impact than actually achieved. Warning signs include:

• Vague impact claims without metrics
• Output metrics confused with outcome metrics
• Attribution of impact beyond what's justified
• No independent verification
• Impact not integrated into investment decisions

Best Practices

• Clear theory of change
• Specific, measurable metrics
• Conservative attribution
• Third-party verification
• Honest about limitations and uncertainties

Blended Finance

Blended finance uses catalytic capital from public or philanthropic sources to mobilize private investment in sustainable development:

Structure

• Concessional capital takes higher risk or lower returns
• Private capital receives improved risk/return profile
• Combined structure achieves impact not achievable by either alone

Instruments

• First-loss capital
• Guarantees
• Technical assistance grants
• Concessional debt tranches
• Equity risk-sharing

Examples

• Development finance institutions providing guarantees
• Foundations providing first-loss capital
• Grant funding for project development

Impact Investing in Practice

Private Equity and Venture Capital

• Direct investments in companies with impact models
• Active ownership and engagement
• Longer time horizons often appropriate
• Examples: clean technology, financial inclusion, sustainable agriculture

Private Debt

• Impact-focused lending
• Green bonds and sustainability-linked bonds
• Microfinance and financial inclusion lending
• Examples: renewable energy project finance, affordable housing

Public Equities

• Investment in listed companies with positive impact
• Shareholder engagement for change
• Impact fund strategies
• Debate about additionality in secondary markets

Real Assets

• Sustainable forestry
• Conservation land
• Green real estate
• Sustainable infrastructure

Case Study: Climate Tech Venture Capital

The growth of climate tech venture capital illustrates impact investing dynamics:

Market Growth

• Climate tech VC has grown from under $1 billion annually to over $40 billion
• Investments span energy, transportation, agriculture, buildings, industry
• Mix of early-stage and growth investments

Impact Thesis

• Early-stage capital can accelerate development of climate solutions
• Successful exits demonstrate viability, catalyzing mainstream investment
• Portfolio approach accepts some failures for breakthrough successes

Challenges

• Long development timelines for deep tech
• Capital-intensive sectors challenging for VC model
• Balancing financial and impact objectives
