The global Environmental, Social, and Governance (ESG) investing market exceeded $30 trillion in 2023, a 50% increase compared to 2016. ESG stands as a vital driver shaping the process of capital allocation. Institutional investors have started incorporating ESG criteria into their portfolio design processes, credit model assessments, and regulatory systems. The financial industry has identified that ESG metrics directly influence investment results.

ESG data use is moving beyond purely ethical investing to enabling risk pricing strategies and long-term return assurance in financial markets. Financial institutions must perform ESG exposure evaluations for all their activities, including lending operations and both underwriting and asset management services. Regulators are also following suit. The climate disclosure rule from the Securities and Exchange Commission (SEC), together with European rules such as the Corporate Sustainability Reporting Directive (CSRD) and the Sustainable Finance Disclosure Regulation (SFDR), and mandatory ESG reporting requirements from Hong Kong and the U.K., have transformed fiduciary responsibilities.

However, market participants struggle with multiple standards guiding their operations despite the existence of the International Sustainability Standards Board (ISSB), the Task Force on Climate-related Financial Disclosures (TCFD), the Sustainability Accounting Standards Board (SASB), and the Global Reporting Initiative (GRI), as well as local and regional requirements. The collection of these ESG frameworks provides guidelines about how institutions should manage their reporting activities, disclosure operations, and risk management procedures. These fragmented ESG information standards work together to achieve their shared objective of delivering usable and comparable ESG information to investors and regulatory bodies across the globe.

The GRI, together with the SASB and the TCFD, has established voluntary frameworks for sustainability disclosure as companies freely decide what to report about their ESG activities.

The ESG reporting environment is undergoing rapid changes. Growth in ESG investing has led to stakeholders requiring standardized reporting that meets reliability standards, along with full accountability measures. The result—a global move from voluntary to mandatory ESG reporting. The European Union (EU), through its CSRD, demands that companies provide extensive ESG information following European Sustainability Reporting Standards (ESRS). The U.S. SEC, through its climate disclosure rule, is anticipated to make listed firms reveal Scope 1 and 2, and maybe even Scope 3 emissions reporting.

The changes go beyond government orders since they represent a strategic business move. Financial institutions must prove the authenticity of their ESG statements through valid verification, also preventing false green-marketing practices, while maintaining sustainable asset values that deliver appropriate risk-based returns. To gain credibility and access to capital markets, organizations need to fulfill the baseline requirements of evolving ESG rules.

Organizations need ESG factors as direct inputs for credit ratings evaluation, as well as risk assessments and capital allocation processes. Credit rating agencies have introduced ESG analysis into their rating systems as climate transition and physical exposure play vital roles in credit quality assessments. Asset managers and banks must have thorough knowledge of these frameworks to assess finance partners and determine loan value and green bond framework, as well as monitor their portfolio’s’ ecological vulnerabilities.

Organizations that do not implement ESG standards must consider this absence more than a missed opportunity as it represents actual legal responsibility. Failure to comply with regulatory requirements under the EU SFDR may lead to penalties. Institutional investors tend to exclude companies with weak ESG scores from their sustainable finance portfolios. The increasing demand from institutions to assess ESG transparency has intensified capital flight and elevated scrutiny for companies operating without proper transparency.

The GRI stands as the worldwide standard framework that companies rely on for their sustainability reporting activities. The GRI demands that businesses reveal the influences their activities have on environmental, societal, and economic elements.

Over 10,000 companies across 100 different countries use GRI standards, which have been established as the primary diagnostic tool for sustainable performance disclosure. GRI reports serve financial institutions by supplying baseline ESG metrics that help them monitor reputational risks and sustainably align with emerging markets, particularly when countries do not provide consistent reporting.

SASB standards assist investors in measuring ESG risks and financial performance opportunities as they help evaluate material impacts on fiscal outcomes. Industrial metrics are also part of this framework; hence, oil & gas companies and banks must measure different factors.

The SASB has transitioned to become a part of the ISSB under the International Financial Reporting Standards (IFRS) Foundation to provide international standards for investor-focused ESG disclosure, globally. Financial institutions can compare portfolios and implement ESG-based equity and credit research through SASB standards.

The TCFD operating framework addresses only financial risks associated with climate change. Organizations must reveal their climate change management procedures through governance disclosure, along with strategy outlines, risk management plans, and metrics including transition and physical risk scenario analyses.

The TCFD receives support from over 3,400 organizations globally, including prominent asset managers and central banks. Large institutions operating in the U.K., as well as in Japan and New Zealand, must now report information following TCFD alignment. The climate disclosure rule proposed by the SEC closely aligns with TCFD requirements; hence, companies pursuing U.S. regulatory compliance need to focus on TCFD standards.

The European Union has adopted the CSRD as a new legislation representing a fundamental progression toward enforced ESG disclosure requirements. The regulations extend to 50,000 companies, together with non-EU businesses with substantial operations or having EU stock listings.

The directive requires detailed, double materiality disclosures under the new ESRS. Financial institutions need CSRD for analyzing ESG data at the portfolio level, as well as controlling supply chain risks and validating the EU market compliance of their clients.

The EU sustainable finance initiative fundamentally depends on the SFDR. The policy introduces mandatory ESG reporting obligations for EU financial product marketing entities, including asset managers, financial advisors, and pension funds.

The SFDR features three types of funds called Article 6, 8, and 9 functions based on how ESG sustainability applies to investment determination. A fund is subject to severe penalties as well as reputational damage when it falsely markets its ESG orientation to financial customers. The key role of the SFDR is the correct classification of funds, the evaluation of ESG product designs, and the validation of green claims made by financial organizations.

The U.S. SEC seeks to establish mandatory climate risk disclosure standards that follow the TCFD. The proposed regulation sets requirements for public corporations for reporting their Scope 1 and Scope 2 emissions, whereas the disclosure of Scope 3 emissions depends on specific circumstances.

This regulatory measure represents a major transformation of ESG monitoring standards within U.S. financial institutions, while it remains in the examination process. U.S. stakeholders actively support the ISSB initiative as it focuses on establishing universal sustainability disclosure standards. Asset managers and institutional investors must align with SEC and ISSB requirements to ensure accurate reporting, properly assess climate risks, and maintain regulatory compliance.

With its leadership in ESG regulation, the EU launched the ESRS through the CSRD. The standards apply to over 50,000 EU-active businesses, and entities connected to EU businesses, through extensive double materiality-based reporting requirements.

The EU Taxonomy merges sustainable enterprise classification and specific guidelines for investment sustainability. These frameworks directly influence how ESG funds are labeled and financial capital distribution and assessment procedures are performed by investors. Financial institutions, both raising funding and investing within the EU, need to follow these definitions for their portfolios or risk fund restrictions and negative reputational impacts.

Asian-Pacific regulatory frameworks for ESG policies show limited unification, but major markets are accelerating their rulemaking.

• All main board issuers in Singapore must report climate-related information using TCFD guidelines starting FY2023.
• The Financial Services Agency of Japan established April 2022 as the start date for required climate disclosure among listed firms following TCFD guidelines.
• Starting from the fiscal year 2023–24, the Securities and Exchange Board of India (SEBI) requires the top 1,000 listed companies registered with the authority to submit Business Responsibility and Sustainability Reports (BRSR).

Financial institutions now view ESG implementation as mandatory due to rising risks. Several aspects of creditworthiness and financing costs, together with portfolio performance duration, now depend heavily on ESG factors. As reported by Moody’s, ESG criteria integration exists in over 30% of its credit rating processes.

Institutional investors now factually evaluate climate and governance risks through measures such as the BlackRock policy of voting against boards without climate disclosure. The financial risk management process must focus on ESG as poor ESG performance alongside inadequate transparency leads to rating downgrades and financial cost increases and attracts investment exits.

The ESG-integration process has progressed; however, data fragmentation still hinders integration efforts. Institutions find it difficult to assess ESG performance with voluntary and mandatory frameworks using different metrics. The world is witnessing active initiatives for achieving global consistency.

The ISSB is developing a single global baseline standard for sustainability reporting that will unite the requirements of IFRS and CSRD/ESRS established by the EU. The implementation of ISSB-aligned frameworks by financial institutions brings benefits including standardizing data comparisons and building investor trust with additional regulatory preparation capabilities, especially across different jurisdictions.

ESG regulatory frameworks across the world have started changing swiftly with investors having increased oversight, governments setting directives, and stakeholders demanding reliable sustainability information. Financial institutions are facing a global capital market transformation due to new EU requirements, including the CSRD and the SFDR, as well as upcoming SEC regulations and similar standards from the ISSB.

Organizations that implement ESG standards lower their risk of greenwashing accusations while increasing their credibility, gaining access to environmentally focused capital, and strengthening their investment diversity.

The current scenario demands that all financial institutions build facilities to accommodate ESG initiatives, alongside the development of exclusive ESG competence and the inclusion of ESG information into traditional financial statements. Sustainability-driven finance has now shifted from being a niche to becoming a requirement, which is enabling organizations to maintain investor trust and ensure lasting performance excellence.
