Belem, 14 November 2025 – Today, Climate Bonds Initiative and the Japan International Cooperation Agency (JICA) have signed a Memorandum of Understanding (MoU) to strengthen cooperation in mobilising private capital for climate-resilient and low-carbon development. The agreement was formalised during COP30 in Belem, Brazil, at the International Development Finance Club (IDFC) Pavilion, Blue Zone. 

Knowledge Sharing for Climate Resilience and Transition Finance 

Under this partnership, Climate Bonds and JICA will exchange knowledge and collaboration that enhance climate resilience and support credible transition finance in developing and emerging economies.  

Strengthening Japan’s Green Transformation (GX) 

Since 2024, the Japanese government has issued JPY 3.6 trillion USD 24 billion amount in Climate Transition Bonds 

The MoU builds on Japan’s momentum in accelerating its Green Transformation (GX) targets — from the launch of the Team Sapporo-Hokkaido's Framework to the issuance of the world’s first Resilience Bond from the Tokyo Metropolitan Government.With geopolitical challenges and high dependence on fossil-fuel imports, Japan is investing strategically in clean energy and regional revitalisation to enhance energy security while advancing net-zero by 2050. This partnership with JICA underscores Japan’s commitment to scaling transition finance that drives both economic competitiveness and climate resilience. 

Sean Kidney, CEO, Climate Bonds Initiative: 
 “Our collaboration with JICA is a critical step toward mainstreaming resilience and transition finance across ASEAN. Together we can mobilise private capital at scale to support countries that are building low-carbon economies while strengthening their adaptation to climate impacts.” 

Kyosuke Inada, Director General for Sustainability Management, JICA:  

"Through the enhanced partnership with Climate Bonds, which is renowned for its expertise to mobilise capital for climate action, we are looking forward to contributing to the resilience and GX in the world and Japan." 

Earlier this year, Climate Bonds Initiative delivered expert sessions on transition finance and taxonomy-interoperability in collaboration with JICA and regional governments, underlining Japan’s global leadership and deepening its role in enabling credible transition pathways.
