🌍 Introduction: Accelerating Global Climate Solutions Through IKI
The International Climate Initiative (IKI) continues to stand at the forefront of global climate and biodiversity financing. Known for its robust, multi-tiered funding ecosystem, IKI provides organisations with opportunities to deliver transformative, sustainable action in developing and emerging economies.
As of late 2025, three major competitive calls are open, offering funding windows for large-scale, mid-sized, and community-level climate and biodiversity projects. These opportunities reflect IKI’s commitment to innovation, global cooperation, and the urgent need for comprehensive climate solutions.
🏛 IKI’s Funding Philosophy: A Balanced, Strategic Approach
IKI operates under a dual funding philosophy that integrates competitive and non-competitive funding streams. This approach ensures that both groundbreaking innovation and strategically aligned climate priorities receive support.
Competitive Selection: Encouraging Innovation
Competitive funding streams—Large, Medium, and Small Grants—serve as IKI’s core mechanisms for identifying high-quality, scalable projects. These selection processes attract experienced implementers capable of driving meaningful climate mitigation, adaptation, and biodiversity conservation.
Non-Competitive Processes: Targeted Impact
In parallel, IKI utilises non-competitive funding to:
- Support multilateral climate initiatives
- Increase climate finance mobilisation
- Establish IKI interface offices in priority partner countries
This mixed model empowers IKI to respond dynamically to global climate needs while maintaining alignment with the IKI Strategy 2030, which guides thematic and strategic priorities.
