Asia Faces $200 Billion Annual Climate Change Adaptation Financing: Report

Asia faces a widening climate adaptation and resilience (CA&R) financing gap that could exceed 75% of the global deficit by 2030, according to a new report.

More than $200 billion is needed annually for climate adaptation and resilience across the region, but current financial flows amount to only about $19 billion per year, according to the report.

message, “Climate Adaptation and Resilience in Asia: Pricing Risk, Sizing Opportunities, Financing Solutions”issued by the Center for Impact Investing and Practices in collaboration with Temasek, Invesco and ImpactSF (CGIAR Hub for Sustainable Finance) at the Philanthropy Asia Summit (PAS) which started here on 18 May.

The study identified more than 250 priority climate adaptation and resilience (CA&R) solutions across Asia, based on an analysis of financial flows worth more than US$100 billion between 2021 and 2025.

It warned that while Asia is warming at nearly twice the global average, funding for climate change adaptation remains far below what is needed.

The report says 3.7 billion people in Asia have been affected by climate-related disasters since 2000, more than three times the number affected in the rest of the world combined.

Asian societies are projected to face annual climate-related costs of approximately US$336 billion by 2030, underscoring the economic risks of delayed adaptation action.

The researchers categorized 250 climate solutions into three tiers based on commercial viability: 94 solutions with little or no commercial viability but critical to building resilience, 93 new opportunities requiring catalytic capital, and 65 commercially viable solutions with proven market outcomes.

The report also launched a regional finance panel tracking public, private and philanthropic capital flows across China, India and Southeast Asia, along with a case study library of 50 examples of climate adaptation initiatives.

Agriculture has emerged as one of the sectors most at risk from climate change, particularly in Southeast Asia.

The report warned that climate stress could reduce crop yields in the region by up to 41%, threatening the livelihoods of some 100 million smallholder farmers, many of whom survive on less than $2 a day.

While agriculture contributes nearly 10% to Southeast Asia’s GDP, growth in production of key staple foods has remained below 1.3% per year over the past decade, the report said.

Researchers have identified several barriers that limit investment in climate change adaptation projects, including weak policy frameworks, a lack of reliable data on climate risks, fragmented funding structures and difficulties in scaling localized solutions.

Despite the challenges, investor interest in financing climate change adaptation is growing. Among the 165 Asian funders surveyed for the study, nearly half said they were already investing in climate adaptation and resilience, while another 28% were exploring investments in the sector. Together, these donors manage more than $1 trillion in assets.

“Financing climate adaptation and resilience in Asia remains constrained by limited data, fragmented approaches and uncertainty about where capital can be most effective,” said Dawn Chan, CEO of the Center for Impact Investing and Practices.

“As climate risks intensify, stronger coordination between public, private and philanthropic capital will be necessary to accelerate action,” she added.

The report called for coordinated reforms, including better valuation of climate risks, stronger financial systems, better infrastructure for data sharing and closer cooperation between governments, investors and philanthropic organizations to scale up adaptation finance across Asia.
