Brazil has issued a final appeal for countries to submit updated climate action plans before a crucial September deadline, warning that failure to do so could undermine efforts to keep global warming within 1.5°C.
So far, only 28 nations have submitted their nationally determined contributions (NDCs), leaving some of the world’s largest emitters yet to act. Brazil, host of the upcoming Cop30 climate summit, has called for governments to deliver their proposals by September 25, when a key meeting will take place in New York. The submissions will be used to compile a global progress report ahead of the summit in November.
André Corrêa do Lago, the Brazilian diplomat presiding over Cop30, stressed that these plans are not just long-term targets but represent a collective vision for a sustainable future. He warned that if pledges fall short, stronger measures may be required during the summit.
Concerns remain over logistical challenges in Belém, the host city, where limited accommodation and high costs have raised doubts about accessibility for smaller nations and civil society groups. Organizers have sought to ease these issues by expanding lodging options and promising greater transparency in preparations.
As the deadline approaches, Brazil continues to push for ambitious commitments, framing the success of Cop30 as vital to global climate trust and cooperation.
