At the climate COP31 discussions, a major goal carried over from previous UN climate negotiations is the mobilization of $1.3 trillion per year in climate finance to support developing countries’ climate mitigation and adaptation efforts by 2035. This figure represents the scale of investment that negotiators and climate finance experts argue is needed — from both public and private sources — to help poorer nations build resilience against climate impacts, transition to low‑carbon economies, and meet their Paris Agreement commitments. The figure was highlighted as part of the roadmap discussions on how to significantly scale up finance beyond earlier targets.
This $1.3 trillion goal is not about a military or space budget, but specifically about ensuring that adequate funds flow into climate action in developing economies, where impacts are often the most severe and financial capacity is the weakest. While developed countries had previously agreed to provide at least $300 billion per year by 2035, the broader objective of mobilizing $1.3 trillion reflects the full scale of investment needed — including substantial private sector contributions — to address climate challenges effectively.
