CLIMATE SUMMIT 2025: The path to COP30

The summit, which takes place on September 24 at the UN headquarters, is designed as a launch of COP30, but, unlike the tentacular negotiations of a conference on the United Nations climate, it is a high -level targeted event where heads of state, government leaders, businesses and civil society are supposed to present concrete producers and new national climate plans.

According to the organizers, the summit has a clear mandate: the parties to the Paris Agreement – The 2015 historical commitment to a Treatise on Climate Change – must present new NDCs or updated (contributions determined at the national level or promises to take measures to fight against the climate crisis) which reflect “daring action for the next decade”.

The head of the UN António Guterres made it simple: the existing commitments are far from sufficient, and only a fraction of the Member States has updated NDC for 2025. Current national plans, according to the UNCCCCReduced only 2.6% of global emissions by 2030 compared to the levels of 2019, a tiny fraction of the reduction of 43% which, according to scientists, is necessary to maintain global temperatures at no more than 1.5 degrees Celsius above pre-industrial levels.

The summit therefore serves both as a point of pressure and an opportunity. We expect the leaders not only to remain commitments, but to announce new NDCs, show how they will be implemented and underline how they align themselves with the acceleration of the transition of clean energy.

Why now?

The urgency of the summit is sharpened by scientific and political realities. The United Nations World Meteorological Organization reported that 2024 was the hottest year recorded, with global temperatures of 1.6 degrees Celsius above pre-industrial levels. Meanwhile, the international political landscape has developed more fractured.

The United States, which withdrew from the Paris Agreement at the beginning of 2025, remain one of the largest historical issuers. His retirement from climate finance and proper energy commitments left the developing countries wondering if the promised support flows will materialize.

At the same time, a real momentum exists. The clean energy investment exceeded 2 dollars of dollars in 2024, exceeding fossil fuels for the first time, and initiatives such as the non-proliferation treaty for fossil fuels offered are gaining ground. The summit will test if these positive trends can be exploited and set up.

Read between the lines

The climate summit is not a negotiation session, but its results will set the tone for COP30 in Belém. Brazil has promised to focus this conference on climate justice, forest protection and renewable energies. However, success in Belém will strongly depend on what is going on in New York this week.

Observers will closely monitor three signals. First, will the major issuers bring plans that make up for the gap in shows? Secondly, is climate financing extended beyond symbolic commitments, in particular for the loss and damage fund (which has attracted a little less than $ 789 million, far from what is necessary)? And finally, will leaders recognize that the expansion of coal, oil and gas is incompatible with Parisian targets?

Without progress on these fronts, COP30 risks becoming another forum of unsatisfied expectations.

For the UN chief, the summit is more than the process. It is a question of rebuilding confidence in multilateralism at a time when global divisions widen and demonstrate that climate action can unlock economic and social advantages. “The opportunities for climate action have never been clearer,” said the UN, stressing job creation, health and energy safety improvements related to clean energy expansion.

However, for the communities of Pakistan and India moved by destructive floods, or for farmers of the Horn of Africa faced with drought, the summit is less a matter of opportunity than survival. The gap between the climatic impacts and the political response has never felt wider.

The United Nations Climate Summit of September 2025 does not replace COP30, but it can be just as decisive. It is the arena where managers can reset ambition, inject credibility and gain momentum to Brazil.

If he can offer new bold promises, credible finances and a clear direction on fossil fuels, he could help save the promise of Paris.
