This document discusses results-based finance (RBF) and how it can support short-term climate impact. RBF ties finance to the achievement of predefined results rather than to inputs or processes. It has been used in development finance and is inherent in climate mechanisms like the CDM, REDD+, and NAMAs. RBF comes in various forms from upfront payments to payments for emissions reductions or ecosystem services. Lessons from the CDM show that ex-post finance requires pre-financing, enabling measures are key, and recurring payments can help ensure long-term success of interventions. RBF may help link carbon markets and climate finance by supporting short-term emissions reductions while piloting new approaches.
