The article aims to determine the "portfolio" of financing ecosystem-based adaptation to climate change based on the analysis of traditional market instruments used to preserve, maintain and restore ecosystem services and biodiversity. The definition of ecosystem-based adaptation, its qualification criteria and elements of their application in contrast to traditional economic measures for biodiversity and nature conservation are revealed. The relevance of using ecosystem and nature-based approaches to adapt to climate change and reduce the risk of natural disasters given the increasing frequency of extreme weather events associated with climate change – severe droughts, floods, heatwaves, storms and other hazards are explored. Accordingly, the urgency of adaptation to climate-related risks and hazards in different economic sectors, e.g. agriculture, land use, fisheries, and natural components with a focus on the climate impacts prognosis for the European region, using effective and affordable measures with additional long term social and environmental benefits are explained. Trends and specific gaps in the international experience in financing climate adaptation measures are considered. The most common instruments for financing nature-based solutions and ecosystem-based adaptation to climate change, which are already used in world practice or have the potential of their practical implementation in various sectors, including environmental and carbon taxes, subsidies, tradable environmental permits, risk insurance, obligations, debt and equity instruments, as well as innovative forms of green loans, green bonds, and climate-related insurance types are systematized and represented. The specifics of financing such measures through international funds, development banks and European Union funds are considered. Possibilities of integrating financing of ecosystem-based adaptation to climate change to the current processes of climate change adaptation policy development of Ukraine, particularly in the context of performance of obligations under the Paris climate agreement, are considered.
