The International Climate Initiative (IKI) supports large-scale climate and biodiversity projects in developing and emerging countries, aiming to limit global warming to 1.5°C and halt biodiversity loss. IKI Large Grants fund ambitious interventions that strengthen legal frameworks, advance NDCs and NBSAPs, and mobilize communities and resources for sustainable, low-emission development.
Overview of the IKI Large Grants
The IKI, funded by the German Federal Government, is a flagship initiative for international climate and biodiversity action. It assists developing and emerging countries in adapting to climate change, mitigating greenhouse gas emissions, and conserving ecosystems. The Large Grants instrument specifically targets ambitious, high-impact projects that drive systemic and sustainable transformations.
