The extent to which an outcome (impact or investment) would not have occurred without the intervention or capital. A core question in evaluating impact credibility.
Context: Central to determining whether an investment truly creates impact beyond what would have happened anyway. Investors assess whether their capital enabled improvements in scale, speed, quality, or viability that wouldn't otherwise occur. For enterprises, additionality might mean reaching underserved populations or geographies, while for investors it often relates to providing finance on terms unavailable from commercial sources.
Example: A lender offers below-market terms that make a health clinic viable in an underserved rural area; without this financing, the clinic would not exist and the community would lack healthcare access.
The portion of observed change that can reasonably be credited to a specific intervention or actor, distinguished from outcomes influenced by external factors.
Context: Attribution addresses the fundamental question: "Did our intervention cause this change?" It's particularly challenging in complex environments where multiple actors and factors influence outcomes. Rigorous attribution often requires experimental or quasi-experimental designs (like RCTs or matched comparison groups) to isolate the intervention's effect from confounding variables. In impact investing and philanthropy, strong attribution claims require evidence that goes beyond correlation to demonstrate causation.
A reasoned estimate of what would have happened without the intervention.
Long-term effects on people and planet due to an intervention, policy, or investment.
Explicit intention to achieve positive social/environmental outcomes.
Topics significant to decision-makers. Single materiality considers financial materiality only (impact on enterprise value). Double materiality considers both the impact on enterprise value AND the enterprise's impacts on society and environment.
Context: Double materiality is embedded in EU disclosure regimes including CSRD/ESRS, requiring companies to report on how sustainability matters affect them financially AND how they affect people and planet. ISSB focuses on investor-oriented single (financial) materiality globally. This distinction creates complexity for multinational companies reporting under multiple frameworks. Many leading investors now argue that comprehensive double materiality analysis provides better risk intelligence than financial materiality alone.
Any person or group materially affected by an organization's activities.
A causal map that articulates how inputs and activities lead to outputs, outcomes, and impacts, including underlying assumptions and risks. Essential for strategic alignment and accountability.
Context: Used across programs, funds, and enterprises to align strategy with data collection and reporting. A well-developed ToC makes explicit the causal pathways through which change is expected to happen, identifies key assumptions that must hold true, acknowledges external factors that could influence success, and provides a framework for monitoring and evaluation. Effective ToCs are developed participatively with stakeholders and updated as learning occurs.
Example: A workforce training program's ToC might show: Inputs (funding, trainers) → Activities (skills training, job placement) → Outputs (# trained) → Outcomes (employment rate, wage increases) → Impact (reduced poverty), with assumptions like "local employers have job openings" and risks like "economic downturn."
Third-party certification administered by B Lab for companies meeting rigorously verified standards of social and environmental performance, accountability, and transparency. Distinct from the Benefit Corporation legal structure.
Context: To achieve B Corp Certification, companies complete the B Impact Assessment (BIA) covering governance, workers, community, environment, and customers. Minimum score of 80/200 required. Companies must also make their impact publicly transparent and legally commit to stakeholder governance (often through adopting Benefit Corporation legal form where available). Over 8,000 B Corps certified globally across 90+ countries. Certification must be renewed every three years. B Lab also maintains industry-specific standards and the B Analytics platform for benchmarking.
Example: Patagonia, Warby Parker, and Ben & Jerry's are well-known B Corps that balance profit with purpose, meeting high standards for environmental and social practices.
Statutory corporate form embedding public-benefit purpose into directors' duties.
US-based financial institutions providing affordable lending in underserved markets.
Member-owned, democratically controlled enterprise ("one member, one vote").
Revenue-generating enterprise pursuing a defined social/environmental mission.
The strategic use of concessional development finance and risk mitigation from public or philanthropic sources to mobilize additional private sector investment toward sustainable development in emerging markets and developing economies (EMDEs).
Context: Blended finance addresses the gap between available commercial capital and the financing needs of SDG-aligned projects in developing countries. Common structures include first-loss guarantees, concessional loans, technical assistance grants, and currency hedges that de-risk investments for commercial investors. The OECD has established principles for blended finance focused on anchoring blended finance use to development rationale, designing structures to increase mobilization, tailoring to local context, focusing on effective partnering, and monitoring impact.
Example: A Development Finance Institution provides first-loss capital covering the riskiest 20% of a renewable energy fund in Sub-Saharan Africa, enabling commercial banks to co-invest in the remaining 80% they would otherwise consider too risky.
Capital accepting higher risk or below-market returns to unlock additional investment.
Outcomes-based contract where investors are repaid if pre-agreed results are verified.
Investments made with the intention to generate positive, measurable social and environmental impact alongside a financial return. Distinguished by intentionality, evidence, and contribution to impact.
Context: The term was coined at a 2007 Rockefeller Foundation convening. The GIIN identifies four core characteristics: intentionality (explicit goal to create impact), evidence and impact data (commitment to measurement), financial returns (expectation of capital return), and range of asset classes (applicable across public/private markets, debt/equity). Impact investing spans from concessionary capital accepting below-market returns to market-rate investments targeting competitive returns. The market has grown to over $1 trillion in assets under management globally.
A comprehensive catalog and system of standardized impact metrics and core metric sets developed by the GIIN to measure, manage, and optimize impact across common themes, sectors, and strategic goals in impact investing.
Context: IRIS+ (the successor to IRIS) provides over 600 standardized metrics that enable comparability and aggregation across portfolios. Core Metrics Sets guide investors and enterprises to the most relevant indicators for their impact objectives (e.g., financial services, agriculture, climate). The system is widely used by impact investors, fund managers, and enterprises globally and integrates with other frameworks including the SDGs and GRI. IRIS+ also provides guidance on aligning metrics with the Impact Management Project's five dimensions of impact.
US foundation investments primarily for charitable purposes; count toward 5% payout.
Global investor network supporting ESG integration via six voluntary principles.
Outcomes-based financing mechanism where government or other public sector entity repays private investors if pre-agreed social outcomes are achieved and independently verified. Also known as Pay-for-Success contracts in the US.
Context: First launched in the UK in 2010 to reduce recidivism at Peterborough Prison, SIBs have since been implemented globally in areas like homelessness, early childhood development, workforce development, and healthcare. The structure transfers delivery risk from government to private investors and service providers, while focusing on outcomes rather than outputs. Success payments are typically made only if verified outcomes exceed a predetermined threshold. Critics note transaction costs and complexity; proponents argue SIBs drive innovation and prevention-focused approaches.
Example: A city contracts with investors who fund an organization providing intensive support to chronically homeless individuals. If independent evaluation shows a 40% reduction in emergency room visits and shelter nights, the city repays investors with a modest return.
A structured approach to cross-sector collaboration requiring five conditions: a common agenda, shared measurement systems, mutually reinforcing activities, continuous communication, and backbone support organizations. Used to address complex, systems-level social challenges.
Context: Introduced in a 2011 Stanford Social Innovation Review article by Kania and Kramer, collective impact differs from traditional collaboration by requiring all participants to abandon their individual agendas in favor of a shared approach. The backbone organization (often funded separately) provides dedicated staff and infrastructure for coordination, data management, and communication. Critics note power dynamics and whether top-down structures truly represent community voice. Examples include StriveTogether (education), Shape Up Somerville (public health), and Elizabeth River Project (environmental restoration).
Flexible, multi-year funding to cover core organizational costs.
High-engagement support combining grants, patient capital, and hands-on capacity building.
Corporate responsibility for social, environmental, and ethical performance beyond compliance.
The Corporate Sustainability Reporting Directive is an EU regulation requiring comprehensive sustainability reporting based on double materiality principles, using the European Sustainability Reporting Standards (ESRS) developed by EFRAG. It significantly expands the scope and depth of mandatory corporate sustainability disclosure in Europe.
Context: CSRD replaces and expands the Non-Financial Reporting Directive (NFRD), applying to approximately 50,000 companies versus 11,000 under NFRD. Implementation is phased starting 2024 for large EU companies, extending to SMEs and non-EU companies with significant EU operations. CSRD mandates double materiality assessment, requires third-party assurance, specifies digital tagging for data, and imposes penalties for non-compliance. The directive aims to combat greenwashing and provide investors with comparable, reliable sustainability information.
The systematic and explicit consideration of environmental, social, and governance factors in investment analysis and decision-making processes. A core component of responsible investment practice focused primarily on financial materiality.
Context: ESG integration means incorporating ESG information into traditional financial analysis to better understand risks and opportunities affecting long-term returns. Not synonymous with impact investing—ESG integration may focus solely on how ESG factors affect enterprise value (financial materiality) rather than the enterprise's impact on stakeholders. Methods include adjusting financial models for ESG risks, using ESG data in security selection, engaging companies on material ESG issues, and scenario analysis. The CFA Institute's ESG certificate program and UN PRI provide guidance on integration practices across asset classes.
Global standards for sustainability reporting focused on impacts on economy, environment, people.
The International Sustainability Standards Board, established by the IFRS Foundation, develops global baseline sustainability disclosure standards focused on investor materiality. IFRS S1 covers general sustainability-related disclosures; IFRS S2 addresses climate-related disclosures building on TCFD recommendations.
Context: Created in 2021 at COP26 to consolidate the sustainability reporting landscape, ISSB aims to deliver a global baseline that jurisdictions can build upon. SASB Standards now sit under ISSB providing industry-specific guidance. Unlike GRI's impact materiality or ESRS's double materiality approach, ISSB focuses on enterprise value creation and risks that matter to investors (financial materiality). The standards are being adopted or considered by jurisdictions worldwide, including through incorporation into securities regulations.
Industry-specific standards identifying sustainability topics likely to affect enterprise value.
EU regulation requiring sustainability disclosures by financial market participants.
Systematic assessment of design, implementation, and results.
Ongoing process to set intentions, assess effects, set goals, measure, learn, and adapt.
Framework for monetizing social outcomes to compare benefits and costs.
The 17 United Nations Sustainable Development Goals with 169 targets guide global action by governments, businesses, and civil society through 2030. They address interconnected challenges from poverty and inequality to climate action and sustainable consumption.
Context: Adopted by all UN Member States in 2015 as part of the 2030 Agenda, the SDGs provide a shared blueprint for peace and prosperity. Often used as a taxonomy for impact goal-setting and reporting, though the SDGs themselves are not a measurement framework. The UN maintains official indicators for tracking progress at national level. Organizations like the SDG Impact Initiative (now managed by UNDP) have developed standards to help enterprises align their impact management with the SDGs. Businesses increasingly reference SDG alignment in sustainability reports, with varying degrees of rigor.
Example: A microfinance institution might align with SDG 1 (No Poverty), SDG 5 (Gender Equality by serving women entrepreneurs), SDG 8 (Decent Work and Economic Growth), and SDG 10 (Reduced Inequalities).
Use-of-proceeds bonds where capital is exclusively applied to finance or refinance eligible green projects with environmental benefits. Part of the broader sustainable debt market including social bonds and sustainability bonds.
Context: Frameworks typically align with ICMA's Green Bond Principles covering use of proceeds, project evaluation and selection, management of proceeds, and reporting. Eligible categories include renewable energy, energy efficiency, clean transportation, sustainable water management, climate change adaptation, and circular economy. The market has grown from $11 billion in 2013 to over $500 billion annually. Climate Bonds Initiative provides certification and taxonomy science. Differs from sustainability-linked bonds where coupon varies with issuer-level KPI performance rather than funding specific projects.
Bond whose coupon adjusts based on achieving sustainability KPIs.
Financing for carbon-intensive issuers to decarbonize along credible pathways.
