Macroeconomic costs of climate change and the impact of adaptation

OnlineNov 5, 2025 | 10:30 AM - 12:00 PM

Finance and investment Adaptation and resilience

Description

As the impacts of climate change intensify, the need to understand and quantify the economic costs becomes increasingly urgent. Accurate data and metrics are essential for governments, businesses and communities to make informed decisions about where and how to invest in climate adaptation, and how it is interlinked with mitigation efforts. This session will explore the importance of quantifying country-specific climate costs, the value of investing in both public and private adaptation efforts, and the critical need to measure the effectiveness of different policies and investments. By grounding adaptation strategies in evidence and evaluation, countries can better prioritise and sequence policy actions, allocate resources, and build resilience across sectors and geographies.
