An Overview of Environmental and Social Due Diligence in the Financial and Banking Sector
The environmental and social due diligence in the financial and banking sector is a systematic framework. It helps the financial institutions to identify, evaluate, and monitor risks embedded in the lending portfolios, operational activities, and investment decisions.
Unlike the project-level assessments, ESDD operates at institutional, portfolio, and transaction levels. It ensures that risks are comprehensively addressed across the financial ecosystem.
The environmental and social due diligence in the financial and banking sector comprises portfolio-level screening, transaction-specific due diligence for high-value exposures, climate stress testing, regulatory compliance checks, and social risk evaluation.
With increasing oversight from RBI, SEBI, and the global framework, the ESDD is more necessary to ensure compliance, transparency, and informed decision-making. It helps financial institutions reduce risk exposure, strengthen portfolio resilience, and align with sustainable financing practices.
Overall, the environmental and social due diligence in the financial and banking sector is a crucial tool for balancing compliance, risk management, and sustainable growth.

Schedule a MeetingWhy is ESDD in the Financial and Banking Sector needed?
The need for ESDD in the financial and banking sector is due to several reasons, given below:
Regulatory Mandates Environmental Risk Assessment:
The Reserve Bank of India sets directions on ESG Risk Management in 2023. It makes environmental risk assessment mandatory for commercial banks.
- In December 2024, the RBI mandates climate scenario analysis for every Scheduled Commercial Bank with assets of Rs. 5000+ crore.
- In January 2025, RBI stressed the need for manual testing that requires quarterly assessment of 15 climatic factors.
- Between 2024 and 2026, the RBI imposed a heavy penalty worth Rs. 486 crores on 23 banks for non-compliance in ESG monitoring.
Financial Risk from Environmental Non-Compliance:
Failure in environmental compliance causes heavy financial risk. It accounts for approximately 4.2% of identified NPAs directly linked to environmental violations or uncertain climatic events in 2025, causing Rs. 1.8 trillion additional portfolio stress.
Water scarcity solely accounts for 2.1 trillion, which is 8% of agricultural loan defaults. An inadequately assessed project loan can become a non-performing asset overnight when regulatory issue closure in order for environmental violations.
International Market Access for Indian Banks:
Many financial institutions in India are willing to raise capital through the international market. It is possible that issuing green bonds or participation in syndicate lending shows ESDD capabilities to align with the IFC Performance Standards and the Equator Principles.
There is a total of 12 financial institutions in India, considered as Equator Principles, and collectively manage Rs. 28 trillion in project finance portfolios.
Reputational Risk from ESG Non-Compliance:
In the era of ESG-compliant investors, offering funding to projects with high environmental risk results in severe reputational damage. A bank might face heavy penalties with portfolio review for funding a project that violates the Equator Principles.
Competitive Benefit for ESDD-Compliance Banks:
Financial institutions with a strong ESDD framework obtain benefits as follows:
- Green-classified assets 25% risk-weighted asset discount under Basel III.
- Translate to lower capital requirements and high returns on equity.
ESG-aligned portfolios attract potential investors, sovereign wealth funds, and climate finance allocations. Financial institutions are shifting early in ESGG in the financial and banking sector to build a competitive reputation. But, in cases of inadequate ESDD, financial institutions expose themselves to regulatory penalties and fraud risk.
Who Needs Environmental and Social Due Diligence in the Financial and Banking Sector?
Most financial institutions in India are classified within the ESDD requirement. Here is a list of key institutions that require environmental and social due diligence in the financial and banking sectors. Have a quick look below:
- Public sector banks
- Private sector banks
- Foreign Banks in India
- NBFCs and HFCs
- Microfinance Institutions
- Asset Management Companies
- Development Finance Institutions

Book a 1:1 Virtual MeetingThe ESDD Process: Step-by-Step Environmental and Social Due Diligence in the Financial and Banking Sector
You are required to follow the step-by-step process of environmental and social due diligence in the financial and banking sector. Look at the given process for a successful ESDD in the financial and banking sector.
Step 1: Assess the Institution:
You must evaluate the institution’s current ESG governance norms, policies, data infrastructure, risk management framework, and staff capability against RBI, SEBI, and the international standards. It is necessary to find out the gaps or key challenges that the board oversees, CRO accountability, ESG risk committee functioning, and disclosure process.
Step 2: ESG Policy and Governance Framework Development:
You must draft and secure the approval of the board for the ESG risk management policy. Either establish or strengthen the ESG risk committee and define the CRO’s responsibilities for environmental risk. It is essential to integrate the ESG metrics into the management of KPIs and incentive structures.
Step 3: Portfolio Level Risk Mapping:
You must conduct a comprehensive sector-based environmental risk assessment of the entire lending portfolio. Also, you must classify environmental risk, from high (fossils, chemicals), medium (manufacturing, real estate), to low risk (service, technology).
Step 4: ESG Rating Integration:
You need to develop or adopt an ESG framework for the borrower's assessment. Integrate ESG scores into the existing credit rating models. This will directly influence the lending decisions, pricing, and provisioning under the social and environmental risk.
Step 5: Climate Stress Testing:
You need to implement the RBI-mandated quarterly climate stress testing methodology. The model portfolio impacts different conditions, and it is essential to find out the concentration risk in the carbon-intensive sectors. You must not forget the capital adequacy under the adverse climate scenarios.
Step 6: Transaction Level ESDD Operationalization:
You must establish pre-sanction environmental screening processes for all new loans. For project funds between Rs. 50 crores to Rs.100 crore; it is needed to implement the full ESDD aligned with IFC performance standards.
Step 7: Green Taxonomy Classification:
You must classify the entire loan portfolio against the RBI’s Green Taxonomy framework. It is required to identify the green transition and brown assets. This classification directly impacts the RWA calculations and capital requirements.
Step 8: Disclosure and Reporting:
You must prepare the BRSR reports, TCFD-aligned climate reports, and RBI-mandated quarterly ESG risk reports. It is necessary to ensure 2 independent assurances for large institutions.
Step 9: Training and Capacity Building:
It covers training the credit officers, risk managers, board members, and branch staff on ESG risk assessment. It also covers ESDD procedures and climate risk fundamentals.
Step 10: Ongoing Monitoring and Continuous Improvement:
It is necessary to implement post-disbursement environmental monitoring for high-risk loans. Conduct the annual ESAP progress reviews and update the climate stress test models with the latest data. It is needed to track regulatory developments and adjust the framework proactively.
