Organizations, research institutions, NGOs, governments, and international consortia now have a unique opportunity to secure funding for high-impact initiatives designed to accelerate global climate action.

As one of the world’s leading climate finance mechanisms, IKI channels resources into cutting-edge solutions that combine environmental protection with social and economic benefits. These newly opened calls signal a strong commitment to advancing climate justice, protecting natural ecosystems, and empowering countries to meet their climate and biodiversity targets.

What Is IKI Looking For in 2025?

Each open call seeks well-designed, technically sound, and innovative project concepts that can deliver measurable climate and biodiversity outcomes. IKI prioritizes ideas that:

Strengthen climate mitigation and help reduce greenhouse gas emissions
Accelerate climate adaptation and resilience in vulnerable regions
Protect and restore biodiversity and natural ecosystems
Support transformative policy frameworks at local, national, and regional levels
Foster partnerships between public, private, and civil society actors
Contribute to global frameworks such as the Paris Agreement and Kunming-Montreal Global Biodiversity Framework

Projects should demonstrate long-term sustainability, strong stakeholder engagement, and a clear strategy for replicability or scaling.

Overview of the 3 New IKI Funding Calls

1. IKI Thematic Calls

This call invites comprehensive project proposals focused on major thematic areas such as climate mitigation, climate adaptation, REDD+, biodiversity protection, nature-based solutions, and sustainable land use. Ideal projects include multi-country partnerships, policy transformation, community-centered approaches, and large-scale environmental interventions.

Who should apply:
Consortia involving international organizations, research institutions, NGOs, governmental bodies, and private-sector actors with strong technical capacity.
