The Summit, which takes place on September 24 at the UN Headquarters, is designed as a launch platform for COP30, but, unlike the extensive negotiations of a UN climate conference, it is expected that this is a specific high level event where the heads of state, government leaders, companies and civil society present the specific promises and the new national climate plans.
‘Bold action for the next decade’
According to the organizers, the Summit has a clear mandate: the parts of the Paris Agreement, the 2015 historical commitment of the Climate Change Treaty, must present a new or updated NDC (certain contributions at the national level, or promises to take measures to address the climatic crisis) that reflect “bold action for the next decade.”
The UN Chief, António Guterres, has made it clear: existing promises are not enough, and only a fraction of the Member States has updated NDC by 2025. According to the UNCCC, only 2.6 percent in 2030 compared to the 2019 levels, a fraction of the 43 percent fraction that say that scientists are needed to keep the global temperatures no more. Celsius above preindustrial levels.
Therefore, the summit serves as a pressure point and an opportunity. The leaders are expected not only to reformulate the commitments, but to announce new NDC, show how they will be implemented and highlighted how they are aligned with the acceleration of the clean energy transition.

Why now?
The urgency of the summit is exacerbated by scientific and political realities. The UN World Meteorological Organization reported that 2024 was the hottest year registered, with average global temperatures of 1.6 degrees Celsius above preindustrial levels. Meanwhile, the international political landscape has fractured more.
The United States, which retired from the Paris Agreement in early 2025, remains one of the largest historical emitters. Its withdrawal of the commitments of climatic finance and clean energy has left the developing nations questioning whether the promised support flows will materialize.
At the same time, there is a real impulse. Clean energy investment exceeded $ 2 billion in 2024, exceeding fossil fuels for the first time, and initiatives such as the proposed non -proliferation of fossil fuel proliferation are gaining ground. The summit will prove if these positive trends can be used and climb.

Reading between the lines
The climatic summit is not a negotiation session, but its results will establish the tone for Cop30 in Belém. Brazil has promised to focus that conference on climate justice, forest protection and renewable energy. However, success in Belém will depend largely on what happens in New York this week.
The observers will observe three signals closely. First, will the main emitters bring plans that close the emission gap? Secondly, climatic finances are expanded beyond symbolic promises, especially for the loss and damage fund (which has attracted a little less than $ 789 million in promises so far, far from what is needed)? And finally, will leaders acknowledge that expanding coal, oil and gas are incompatible with the objectives of Paris?
Without progress on these fronts, Cop30 runs the risk of becoming another forum of unsatisfied expectations.
High stakes
For the UN Chief, the summit is more than the process. It is about reconstructing confidence in multilateralism at a time when global divisions are expanding and demonstrating that climate action can unlock economic and social benefits. “The opportunities of climatic action have never been clearer,” emphasized the UN, pointing out employment creation, health improvements and energy safety linked to the expansion of clean energy.
Even so, for communities in Pakistan and India displaced by destructive floods, or for farmers in the Africa horn that face drought, the summit has less opportunities than survival. The gap between climatic impacts and the political response has never felt broader.
From words to action
The September 2025 Climate Summit is not a COP30 substitute, but it can be equally decisive. It is the sand where leaders can restore ambition, inject credibility and generate impulse towards Brazil.
If you can deliver new bold promises, credible finances and a clear direction in fossil fuels, it could help save Paris’s promise.
