Mitigation and decarbonization efforts are falling short of the 1.5°C goal, making adaptation critical. Developing economies are affected the most, despite having contributed the least to the problem. Nearly 98 percent of adaptation finance comes from public actors, with highly fragmented flows from the private sector. As financing needs increase, bringing private sector finance becomes critical and requires reframing adaptation investments from being seen not just as a risk exposure but also as an investment opportunity. This requires addressing real and perceived investment barriers, public-private collaboration and risk sharing, as well as financial incentives and innovation to unlock scalable, inclusive solutions. Adaptation is more complex than mitigation, with challenges in defining, evaluating, pricing, and scaling investments. Progress on adaptation requires policy reforms, incentives, and partnerships between governments, businesses, and communities and public-private risk sharing.
