Belém, Brazil — The world’s climate negotiators have arrived in the Amazonian city of Belém as COP30 — the 30th United Nations Climate Change Conference — officially begins. Running from 10 to 21 November 2025, the summit is being billed as one of the most consequential climate gatherings in years, as countries confront the widening gap between climate promises and real-world progress.
A Summit Returning to Its Roots
This year’s COP carries strong symbolism. Brazil, the host nation, is the same country that staged the landmark 1992 Earth Summit in Rio — the birthplace of global climate diplomacy. More than three decades later, leaders are returning to South America to reassess commitments under increasing pressure from extreme weather, rising emissions, and the irreversible loss of natural ecosystems.
Belém, located in the Amazon rainforest, places the world’s largest tropical forest — and the communities protecting it — at the centre of global negotiations. Brazil has framed this COP as an opportunity to elevate Indigenous voices and highlight the inseparable link between climate stability, biodiversity and forest conservation.
Why COP30 Matters Now More Than Ever
The summit comes at a critical juncture. It marks the first major climate gathering where nations openly acknowledge that the world is no longer on track to limit global warming to 1.5°C — the key threshold set by the 2015 Paris Agreement. With emissions still rising and climate impacts accelerating, negotiators face intensifying pressure to deliver stronger, more concrete outcomes.
For many vulnerable nations — especially small island states and African countries — COP30 is seen not as a diplomatic ritual, but as a lifeline.
COP30 has brought together a diverse mix of governments, scientists, civil society groups, Indigenous communities, industry representatives and global financiers. Within this vast gathering, several powerful blocs are shaping the direction of negotiations: Small Island Developing States are demanding urgent financial support to adapt to rising seas and worsening climate impacts; the G77 + China bloc is calling for fairer and more consistent climate funding; the BASIC nations — Brazil, South Africa, India and China — are pushing to balance climate ambition with their developmental priorities; and advanced economies are under pressure for slow progress and insufficient financing commitments. As summit host and COP30 president, Brazil wields substantial influence, yet the talks are already clouded by geopolitical tensions, absentee leaders and delayed submission of national climate plans.
Central to the negotiations are three major issues. First, countries are expected to present updated Nationally Determined Contributions, and their ambition levels will determine how close the world stays to the temperature limits set under the Paris Agreement. Second, climate finance remains a critical and contentious topic, with developing nations requiring billions to shift towards clean energy and protect vulnerable communities, while wealthier countries face mounting criticism for not providing adequate funds. Third, the Amazon setting has placed forests, Indigenous rights and biodiversity at the heart of global climate debate, with Brazil seeking stronger international agreements to protect major forests and carbon-rich ecosystems from deforestation, mining and land degradation.
As discussions unfold, COP30 is emerging as a key test of global unity. Despite the familiar scenes of late-night bargaining, shifting alliances and political friction, the stakes are higher than ever. Negotiators must navigate the difficult balance between national priorities and the shared responsibility of addressing a climate emergency that transcends borders. Over Belém’s humid skyline hangs a defining question: can the world finally take the decisive action that science demands, before time runs out?
