United Nations climate chief Simon Stiell has called for stronger political commitment and a major increase in climate ?nancing, saying investments made over the next decade will determine whether the world can successfully transition to a low-carbon future and protect billions of people from worsening climate impacts. Speaking at a joint COP29-COP30 Presidency event during the UN June Climate Meetings in Bonn recently, Stiell said climate ?nance has become the driving force behind the global implementation phase of climate action. ‘This is an era of implementation in climate action, and ?nance will drive it forward,’ said Stiell, Executive Secretary of UN Climate Change (UNFCCC). ‘It is essential for a truly global transition, for turning plans into projects, bringing the bene?ts of climate action to billions of people, and laying the groundwork for more ambitious commitments that science demands.’ Stiell highlighted the commitment made by countries at COP29 to mobilize $1.3 trillion annually in climate ?nance by 2035 and described the Baku-to-Belém Roadmap as a critical strategy to achieve that target. He said the roadmap sends a strong signal that raising $1.3 trillion is both necessary and achievable.
although it is not a negotiated agreement, the plan re?ects an unprecedented level of engagement, incorporating hundreds of proposals and record submissions from governments, ?nancial institutions, and climate stakeholders. ‘It may not be everything that every party would want, but it is a plan we can and must rally behind,’ he said.
the UN climate chief acknowledged the signi?cant economic challenges facing many developing countries, warning that ?nancial constraints are limiting their ability to invest in climate adaptation and clean energy projects at a critical moment. He stressed that stronger political support across international forums is needed to sustain momentum and ensure the roadmap translates into concrete action. Stiell outlined several immediate priorities, including maximizing the impact of existing climate ?nance, leveraging public funds to attract signi?cantly larger volumes of private investment, and expanding access to affordable capital. He also emphasized the need to improve coordination within the fragmented climate and development ?nance landscape, address debt distress in developing countries, and reshape perceptions of investment risk that often discourage funding in vulnerable nations.
other priorities include aligning investment frameworks with global climate goals and identifying innovative sources of climate ?nance to support long-term implementation efforts. Stiell said collaboration with successive COP presidencies would be essential to maintain progress and strengthen international partnerships ahead of the second Global Stocktake at COP33. By then, he said, countries must be able to demonstrate measurable progress in scaling up climate ?nance and delivering tangible outcomes. ‘We have a plan,’ Stiell said in closing. ‘Let’s put it to work.’ Climate ?nance is increasingly viewed as a cornerstone of global efforts to limit temperature rise, strengthen resilience in vulnerable communities, and accelerate the transition toward cleaner and more sustainable economies.
