BELEM: COP30, held in the Brazilian city of Belem on the edge of the Amazon, concluded on Saturday a day later than scheduled, leaving delegates with mixed feelings. While some hailed the conference as a success, others expressed disappointment over inadequate climate finance and the failure to address fossil fuel phase-out.

A key achievement was the adoption of the just transition mechanism, aimed at enhancing international cooperation, technical assistance, capacity-building, and equitable transitions. Civil society groups celebrated the decision as a “historic victory for people power,” emphasizing that it was achieved through the persistent efforts of those living on the frontlines of climate breakdown.
However, adaptation finance for vulnerable communities fell short of expectations. The conference initially aimed to triple adaptation finance to $120 billion by 2030, but the final ‘mutirao’ decision deferred the target to 2035 without a clear baseline. Critics said this leaves the most vulnerable populations inadequately protected against climate impacts.

Fossil fuel phase-out, widely supported by over 80 countries, was omitted entirely from the COP30 agreement. Instead, a roadmap for phasing out fossil fuels and halting deforestation will be presented at COP31, with guidance from an April conference in Santa Marta co-hosted by Colombia and the Netherlands. Environmental groups described this omission as a severe failure.
Observers also highlighted the influence of fossil fuel lobbyists and weak leadership from developed nations, particularly the G20, in diluting outcomes. Calls for UNFCCC reforms, including conflict-of-interest rules and majority voting, were echoed by climate advocates.

The conference also launched the Declaration on Information Integrity on Climate Change, aimed at addressing climate disinformation and promoting evidence-based policies. Despite these steps, experts said COP30 fell short in delivering the necessary finance, ambition, and leadership to meet the world’s climate needs.
