ESG Investing and Impact
Environmental, Social, and Governance (ESG) investing integrates non-financial factors into investment analysis and portfolio construction. The field has roots in religious socially responsible investing (SRI) going back to seventeenth- and eighteenth-century Quaker and Methodist screens against slavery, alcohol, and weapons. Modern ESG emerged around the 2006 launch of the United Nations-backed Principles for Responsible Investment (PRI), which by 2024 had over 5,300 signatories representing approximately USD 120 trillion in assets under management. The 2010s saw mainstream adoption; 2020-2022 was the peak of corporate enthusiasm; and 2023-2025 brought a sharp backlash in the United States while Europe continued tightening disclosure requirements.
ESG Rating Providers
Major ESG raters score companies on environmental, social, and governance metrics, typically blended to a single letter or numeric rating.
- MSCI ESG Research uses a sector-relative AAA to CCC scale across roughly 3,000 underlying metrics. MSCI’s ESG and climate business generates approximately USD 1 billion in annual revenue and is integrated into MSCI’s index franchise.
- Sustainalytics, acquired by Morningstar in 2020, publishes the ESG Risk Rating on a negligible to severe scale based on unmanaged risk exposure.
- S&P Global ESG Scores, built on the former RobecoSAM Corporate Sustainability Assessment, underlie the Dow Jones Sustainability Indices.
- Moody’s ESG Solutions incorporates the Vigeo Eiris business Moody’s acquired in 2019, complemented by Moody’s climate risk and second-party opinion services.
- ISS ESG (Institutional Shareholder Services), spun off from Deutsche Boerse and majority-owned by Genstar as of 2023, provides ratings, controversy screening, and proxy voting recommendations.
- LSEG (formerly Refinitiv) and FTSE Russell ESG integrate ratings into the LSEG data and index franchise.
Berg, Koelbel, and Rigobon’s 2019 (revised 2022) paper “Aggregate Confusion: The Divergence of ESG Ratings” found cross-provider correlations of only 0.54 to 0.61 across the six major raters, far below the roughly 0.99 correlation among major credit rating agencies. The divergence arises from differences in scope (which issues are measured), measurement (how each issue is operationalized), and weighting.
Reporting Frameworks
- Global Reporting Initiative (GRI), founded in 1997 by CERES and the Tellus Institute, publishes the GRI Standards used by most large companies for sustainability reporting. GRI focuses on impact materiality (effect on stakeholders and the environment).
- Sustainability Accounting Standards Board (SASB), founded in 2011 by Jean Rogers (later led by Michael Bloomberg and Mary Schapiro), produced industry-specific standards across 77 industries focused on financial materiality. SASB merged into the IFRS Foundation in 2022, becoming part of the International Sustainability Standards Board.
- Task Force on Climate-related Financial Disclosures (TCFD), established 2017 by the Financial Stability Board and chaired by Michael Bloomberg, structured climate disclosure across four pillars: governance, strategy, risk management, and metrics and targets. The TCFD was absorbed into the ISSB in 2023.
- International Sustainability Standards Board (ISSB), established by the IFRS Foundation in 2021, published IFRS S1 (general sustainability disclosure requirements) and IFRS S2 (climate-related disclosures) in June 2023. Adopters include the United Kingdom, Australia, Brazil, Japan, Singapore, Hong Kong, and Canada (pending).
- EU Corporate Sustainability Reporting Directive (CSRD), effective for large companies from financial year 2024 (first reports 2025) and phased through 2028, requires reporting under the European Sustainability Reporting Standards (ESRS): 12 standards including ESRS 2 General Disclosures, ESRS E1-E5 environment, ESRS S1-S4 social, and ESRS G1 governance, totaling approximately 1,144 data points. CSRD enforces double materiality (both financial and impact materiality).
- EU Sustainable Finance Disclosure Regulation (SFDR), effective March 2021, classifies investment products as Article 6 (no sustainability claims), Article 8 (“light green,” promoting environmental or social characteristics), or Article 9 (“dark green,” explicit sustainable investment objective). The EU Taxonomy Regulation provides the technical screening criteria for six environmental objectives: climate change mitigation, climate change adaptation, sustainable use of water, transition to a circular economy, pollution prevention, and biodiversity.
- CDP (formerly Carbon Disclosure Project) collects annual climate, water, and forests questionnaires from approximately 20,000 companies on behalf of institutional investors and purchasers.
- Science Based Targets initiative (SBTi), jointly run by CDP, the UN Global Compact, WRI, and WWF, validates corporate emissions reduction targets aligned with 1.5 degrees Celsius. Over 7,000 companies had committed by 2024. The SBTi Net-Zero Standard published in 2021 requires deep value-chain reductions plus beyond-value-chain mitigation (BVCM). The April 2024 SBTi board statement permitting wider use of carbon credits for Scope 3 emissions provoked staff backlash and was substantially walked back later in 2024.
GRI and ISSB signed an interoperability memorandum in 2023 to reduce reporting burden.
United States Regulatory Developments
The SEC’s climate disclosure rule was proposed in March 2022 and adopted in scaled-back form in March 2024. The final rule required disclosure of material climate-related risks, Scope 1 and Scope 2 greenhouse gas emissions for large accelerated and accelerated filers (subject to materiality), and climate-related financial statement effects. Mandatory Scope 3 disclosure was dropped. The rule was stayed by the Fifth and Eighth Circuits, and the SEC issued a voluntary pause in April 2024. The Trump administration’s SEC under Chair Paul Atkins (confirmed 2025) declined to defend the rule.
California enacted a more aggressive trio: SB 253 (Climate Corporate Data Accountability Act) requires companies with USD 1 billion or more in revenue doing business in California to disclose Scope 1 and Scope 2 emissions starting in 2026, with Scope 3 in 2027. SB 261 (Climate-Related Financial Risk Act) requires companies with USD 500 million or more in revenue to publish biennial climate financial risk reports. AB 1305 (Voluntary Carbon Market Disclosures) imposes disclosure requirements on entities that purchase or sell carbon credits or make net-zero claims. The Chamber of Commerce filed legal challenges; the laws have largely survived early motions.
Anti-ESG state legislation accelerated from 2021. Texas SB 13 (2021) prohibits state pension funds from investing with firms that “boycott” energy companies; the Texas Comptroller publishes a list of restricted firms. Florida, West Virginia, Tennessee, Oklahoma, Kentucky, Indiana, and over 25 states have enacted variants. The Republican National Committee and state attorneys general pressured net-zero alliances throughout 2023-2025.
Major exits from voluntary net-zero alliances:
- Vanguard left the Net Zero Asset Managers initiative (NZAM) in December 2022.
- JPMorgan Asset Management, State Street, and PIMCO exited NZAM in early 2024.
- BlackRock departed NZAM in January 2025.
- The Net-Zero Banking Alliance (NZBA) lost JPMorgan Chase, Wells Fargo, Bank of America, Citigroup, Morgan Stanley, and Goldman Sachs in December 2024 through January 2025.
- The Net-Zero Insurance Alliance had earlier fragmented in 2023 after Munich Re, Hannover Re, and others withdrew citing antitrust risk.
ESG Fund Assets and Flows
Global ESG fund assets under management peaked above USD 3 trillion in 2022 and declined to roughly USD 2.5 trillion by end-2024, with persistent net outflows in the United States from 2023 onward according to Morningstar Direct data. Europe continues to dominate global ESG AUM at over 80 percent of the global total.
Major ESG ETFs:
- ESGU (iShares ESG Aware MSCI USA) at approximately USD 28 billion is the largest ESG ETF.
- ESGV (Vanguard ESG U.S. Stock).
- SUSL (iShares ESG MSCI USA Leaders) and USSG (Xtrackers MSCI USA ESG Leaders).
- DSI (iShares MSCI KLD 400 Social), the longest-running ESG index ETF, tracking the Domini 400 Social Index dating to 1990.
Active sustainable managers include Domini Impact Investments, Calvert Research and Management (now Morgan Stanley), Parnassus Investments, Pax World, Trillium Asset Management, and Green Century Capital.
Impact private funds:
- Bain Capital Double Impact raised approximately USD 800 million per fund.
- TPG Rise Climate closed Fund I at USD 7.3 billion in 2022; Fund II target USD 10 billion.
- KKR Global Impact Fund I and II.
- Brookfield Global Transition Fund I closed at USD 15 billion in 2022, the largest impact fund to date. Brookfield’s Catalytic Transition Fund closed in 2024 anchored by ALTERRA, the UAE-backed USD 30 billion climate platform announced at COP28.
Impact Investing
The Global Impact Investing Network (GIIN) defines impact investing as intentional, measurable social or environmental impact alongside financial return. The IRIS+ metrics system standardizes impact measurement. GIIN’s 2024 market sizing study estimated total impact AUM at approximately USD 1.5 trillion globally.
Green Bonds and Sustainability-Linked Debt
The first labeled green bond was issued by the European Investment Bank in 2007 (the Climate Awareness Bond). The International Capital Market Association (ICMA) Green Bond Principles, first published 2014 and updated regularly, define the use-of-proceeds standard. Annual green bond issuance exceeded USD 500 billion in 2023. The Climate Bonds Initiative (CBI) provides external certification.
Sustainability-linked bonds (SLBs) shifted the model from use of proceeds to general corporate purposes with coupons stepping up if key performance indicators are missed. Enel was the pioneer with a USD 1.5 billion SLB in 2019 tied to renewable capacity targets. Transition bonds (for hard-to-abate sectors) and social bonds (which scaled during COVID) round out the labeled bond market.
Carbon Credits
Cross-reference EnergyMarkets/carbon-markets-and-compliance for the full treatment of compliance carbon markets (EU ETS, California CCA, RGGI, China national ETS, UK ETS) and voluntary carbon markets.
Major Asset Owners
Public pension funds: CalPERS (USD 500 billion), CalSTRS (USD 350 billion), New York State Common Retirement Fund, and New York City Retirement Systems are influential through both engagement and litigation. Norway’s Government Pension Fund Global, managed by NBIM (Norges Bank Investment Management), held over USD 1.7 trillion in 2024 and is the world’s largest sovereign wealth fund; its Council on Ethics excludes companies violating specific ethical criteria (tobacco, controversial weapons, severe environmental damage, serious human rights violations).
GPIF (Japan’s Government Pension Investment Fund) at USD 1.5 trillion incorporates ESG indices for passive allocation. ABP (the Dutch civil service pension), PFA (Denmark’s largest commercial pension), and AustralianSuper are major European and Asia-Pacific players.
Sovereign wealth funds: Abu Dhabi Investment Authority (ADIA), Mubadala, ADQ, Qatar Investment Authority, Saudi Arabia’s Public Investment Fund, Singapore’s Temasek and GIC. Climate Action 100+ coordinates engagement by over 700 institutional investors with USD 68 trillion in assets across the highest-emitting issuers.
Stewardship and Voting
Proxy advisory services Institutional Shareholder Services (ISS) and Glass Lewis advise institutional voters on every contested proxy item. Their influence has been the subject of regulatory debate including the SEC’s 2020 rule (later rescinded in 2022) requiring proxy advisors to provide companies a copy of their reports before issuing them.
The “Big Three” passive managers (BlackRock, Vanguard, State Street Global Advisors) control over 20 percent of S and P 500 voting power. Lucian Bebchuk and Scott Hirst’s 2019 paper “Index Funds and the Future of Corporate Governance” detailed the agency conflict between passive managers and their beneficiaries.
Engine No. 1’s 2021 campaign at ExxonMobil with USD 12.5 million invested won three board seats against management opposition, the most consequential climate-related proxy fight in United States history. Subsequent activist climate engagements have been mixed; the 2023-2024 proxy seasons saw fewer ESG-themed proposals and lower support rates.
Greenwashing Enforcement
The SEC has brought several enforcement actions for misleading ESG marketing:
- BNY Mellon Investment Adviser USD 1.5 million (2022): the first SEC ESG enforcement action, for misstatements about ESG quality reviews.
- Goldman Sachs Asset Management USD 4 million (2022): for failures in ESG investment process oversight.
- DWS Investment Management Americas USD 19 million (2023): related to greenwashing allegations originating from former sustainability head Desiree Fixler’s 2021 whistleblower complaint; a separate DOJ criminal investigation and German BaFin action also concluded.
In Europe, the EU Green Claims Directive (provisionally agreed 2024) requires substantiation of voluntary environmental claims. The UK Financial Conduct Authority’s Sustainability Disclosure Requirements (SDR) and investment labels regime came into force November 2023; the four labels (Sustainability Focus, Sustainability Improvers, Sustainability Impact, Sustainability Mixed Goals) require qualifying funds to have at least 70 percent assets aligned with the label.
Critiques and Academic Debate
Aswath Damodaran’s “ESG is a mistake” essays argue that ESG is too vague to operate as a discipline and that it conflates value, values, and risk in ways that obscure each. Tariq Fancy, former chief investment officer for sustainable investing at BlackRock, published “The Secret Diary of a Sustainable Investor” essays in 2021 calling much sustainable investing a “dangerous placebo.”
Academic findings are mixed. Hartzmark and Sussman’s 2019 Journal of Finance paper “Do Investors Value Sustainability?” found that high-sustainability funds did not outperform. Pastor, Stambaugh, and Taylor’s 2022 paper “Dissecting Green Returns” distinguished realized from expected returns: green stocks outperformed unexpectedly during the 2010s green-preference shift but had lower expected returns going forward.
Bansal, Wu, and Yaron 2021 found ESG outperformance concentrated in good economic times. The “ESG momentum” effect (improving ESG ratings, not just high static ratings) has shown more robust returns in several studies. Berg, Heeb, and Koelbel 2022 documented that ESG ratings respond more to disclosure than to underlying performance, complicating their use as performance predictors.
Scope 1 / 2 / 3 Greenhouse Gas Accounting
The Greenhouse Gas Protocol (WRI and WBCSD) defines the three scope categories. Scope 1: direct emissions from owned or controlled sources (combustion in boilers, vehicles, process emissions). Scope 2: indirect emissions from purchased electricity, steam, heating, and cooling. Two Scope 2 methods are recognized: location-based (using grid average emission factors) and market-based (reflecting contractual instruments like power purchase agreements and renewable energy certificates). Scope 3: all other indirect emissions in the value chain, broken into 15 categories. Category 1 purchased goods and services and Category 11 use of sold products dominate for most consumer-product companies. Category 15 investments dominates for financial institutions. The Partnership for Carbon Accounting Financials (PCAF) provides financed emissions methodology. PCAF Standard was first published 2020 with version updates through 2024.
EU Taxonomy Technical Screening Criteria
The EU Taxonomy Regulation 2020/852 establishes six environmental objectives. Climate change mitigation and adaptation criteria entered force 2022. Water, circular economy, pollution, and biodiversity criteria entered force 2024. Activities must substantially contribute to one objective, do no significant harm (DNSH) to the others, and meet minimum social safeguards (OECD Guidelines, UN Guiding Principles). Reporting requirements apply to companies subject to CSRD and to financial market participants. The 2022 Complementary Climate Delegated Act controversially included some natural gas and nuclear activities under transitional criteria. European Parliament voted to retain the inclusion in July 2022.
Net Zero Commitments
Roughly 140 jurisdictions have announced net-zero targets covering approximately 90 percent of global GDP. The European Union targets climate neutrality by 2050, with the Fit for 55 package and the European Climate Law making the target binding. The United Kingdom set a legally binding 2050 net-zero target via amendment to the Climate Change Act 2008 in June 2019. The United States rejoined the Paris Agreement under Biden 2021 with a 50 to 52 percent reduction by 2030 from 2005 levels; the Trump administration withdrew again January 2025. China pledged carbon neutrality before 2060 and peak emissions before 2030. India pledged net zero by 2070 at COP26 Glasgow.

Voluntary Carbon Market Detail
The voluntary carbon market grew from approximately USD 500 million in 2020 to USD 2 billion in 2022 before contracting in 2023-2024 amid quality concerns. The Integrity Council for the Voluntary Carbon Market (ICVCM) published Core Carbon Principles in 2023. The Voluntary Carbon Markets Integrity Initiative (VCMI) Claims Code of Practice (2023, updated 2024) governs corporate carbon credit claims. Major standards: Verra Verified Carbon Standard (VCS), Gold Standard, American Carbon Registry (ACR), Climate Action Reserve (CAR), Plan Vivo, and ART TREES (jurisdictional REDD+). Project types: avoided deforestation REDD+, afforestation/reforestation/revegetation (ARR), improved forest management (IFM), agricultural soil carbon, biochar, direct air capture and storage, cookstoves, methane capture, ocean-based.
Article 9 Fund Reclassifications
Article 9 SFDR fund AUM exceeded EUR 500 billion at end-2022 before extensive reclassifications. Roughly EUR 175 billion was reclassified to Article 8 in Q4 2022 and Q1 2023 following ESMA guidance clarifying that Article 9 funds must invest “sustainable investments” only (excluding cash and hedging). Major reclassifiers included BlackRock, Pictet, Axa IM, Amundi, and DWS. The downgrades reduced reputational risk under heightened greenwashing scrutiny.
Diversity and Inclusion Reporting
EEOC EEO-1 component 1 data is required from US private employers with 100+ employees. The SEC Human Capital Disclosure rule (effective November 2020) requires Regulation S-K Item 101(c) human capital description in 10-K. Nasdaq Board Diversity Rule (approved August 2021) required listed companies to disclose board demographic data and either have at least two diverse directors or explain why not. The Fifth Circuit struck down the Nasdaq rule in December 2024 (Alliance for Fair Board Recruitment v SEC). California SB 826 (women on boards) and AB 979 (underrepresented communities) were both struck down by California state courts in 2022.

Climate-Adjusted Returns
Climate factor decompositions in Pastor, Stambaugh, and Taylor 2021 introduce ESG taste shifts. Bolton and Kacperczyk 2021 carbon emissions and stock returns: stocks of high-emission firms earn higher returns (carbon premium). Subsequent literature (Aswani, Raghunandan, Rajgopal 2024) disputes the carbon premium robustness to data corrections.
