Tracking adaptation finance requires defining what counts as adaptation. Different definitions can lead to large variations in the estimated amount of adaptation finance . A further challenge is how to account for adaptation that is mainstreamed, that is, where adaptation-specific investments form only part of a larger programme or budget line, or where actions contribute to adaptation without being labelled as adaptation. These challenges limit the direct comparability between adaptation and mitigation finance . In fact, tracking adaptation finance differs from tracking mitigation finance since activities cannot be a priori assumed to constitute adaptation but instead have to be assessed for their linkage to climate risks in a particular context . Methods for adaptation finance tracking continue to be further developed aiming at better comparability and completeness .
