Environmental, Social, and Governance (ESG) Integration in Climate Finance

Overview

Environmental, Social, and Governance (ESG) integration represents the systematic incorporation of ESG factors into investment analysis, decision-making processes, and portfolio management with particular emphasis on climate-related risks and opportunities. This approach has transformed from a niche investment strategy to a mainstream requirement, with over $35 trillion in global assets under management applying ESG criteria as of 2023.

In climate finance specifically, ESG integration involves identifying material climate risks—including transition risks from policy changes and physical risks from extreme weather—and embedding them into governance structures, investment strategies, risk management frameworks, and performance metrics. This integration is crucial for investors to understand how climate change affects financial returns while also directing capital toward climate solutions and sustainable business practices.
