The UN climate talks at COP30 once again brought the critical issue of climate finance to the forefront of global discussions.
However, while much of the debate revolved around traditional forms of aid directed at developing countries most vulnerable to the impacts of climate change, a faster, more
transformative approach lies in expanding access to carbon markets.
When the world gathered in Glasgow for COP26, the mantra was “building back better.” Two years later, in Sharm El Sheikh, COP27 promised “implementation.” This year, in Belém, Brazil, COP30 arrived with a heavier burden: to finally bridge the chasm between lofty rhetoric and the urgent, measurable steps needed to keep 1.5 °C alive.
On a warm morning at Matemwe, a small crowd gathers behind a rope barrier as the sand begins to tremble. A tiny head pushes through a soft mound of earth, then another, and another. Within minutes, the shallow nest—protected for weeks by a ring of wooden stakes and mesh—comes alive with the rustle of dozens of hatchlings. Volunteers crouch nearby, recording the emergence time and shading the small creatures with their hands to protect them from swooping gulls.
COP30 in Belém is not just another annual climate meeting; it is the 32-year report card of the world governance architecture that was conceived at the Rio Earth Summit of 1992. And that is what report card says: delivery has been sporadic, cosmetic and perilously disconnected with the physics of climatic breakdown.
Belém, at the mouth of the Amazon River, was always going to be a symbolic host for the UN COP30 climate summit, but the mood here has gone far beyond symbolism.
Just 30 minutes from where the UN climate negotiations are unfolding in the port city of Belém, Afro-descendant communities are engaged in a fierce struggle for the full recognition and legal titling of their ancestral territories—critical as their security and livelihoods are compromised by businesses wanting to set up contaminating landfill sites and drug cartels.
The heat in the Hangar Convention Center of the Amazonia, in the northeastern Brazilian city of Belém, has reached the negotiation rooms of the climate summit. Over the past 72 hours, one of the most delicate and significant discussions of this climate meeting has been taking place: the path to progressively abandon the production and use of coal, gas, and oil.
Immaculata Casimero, a leader of the Wapichan Women’s Movement, remembers the beauty of the mountains that are cultural sites to her indigenous community in Guyana.
Mutirão first entered the global climate discourse in Ambassador André Corrêa do Lago’s first letter to the world, which was sent in March 2025 as part of his COP30 presidency.
As the world gathers in Brazil for the UN climate talks, the country’s livestock sector - one of the largest in the world - is understandably in the spotlight.
The urgency of linking climate action with social and wider environmental priorities is clear. Climate change, environmental degradation and violent conflict are often deeply connected and even mutually reinforcing. At the same time, climate action can either support or undermine efforts to improve social justice and halt environmental degradation.
COP30 Brazil, though shadowed by the absence of many world leaders, remains a pivotal milestone in the global fight against climate change, tasked with building on the Paris Agreement’s momentum. Yet the glaring lack of commitment, coupled with withdrawals from the accord, casts a grim shadow over the future. The planet continues to warm, and scientists warn that current targets may not prevent a catastrophic temperature spike. While the summit’s focus on implementation not just new promises—is a welcome shift, it’s clear: words alone won’t cool the Earth.
The climate crisis is getting worse and requires fundamental changes to societies, economies, and our global financial architecture in response. While extreme economic inequality is on the rise – the world's billionaires now hold
more wealth in the world than every country except the U.S. and China – the impacts of climate change are also unequally felt, with the poor in the Global South and North most at risk.
When world leaders now gather in Belém, Brazil for the UN climate conference, expectations will be modest. Few believe the meeting will produce any breakthroughs. The United States is retreating from climate engagement. Europe is distracted. The UN is struggling to keep relevant in the 21st century.
I have been working on climate policy since the late 1990s. I was in the room when Europe’s early carbon market discussions were shaping the architecture that would eventually underpin the Kyoto Protocol.
My recent visit to Brazil coincided partly with the Conference of the Parties (COP) 30, the 30th United Nations Climate Conference in Belém. Although I did not attend COP 30, I was very fortunate to visit the Amazon.
A report by the Global Alliance of Territorial Communities (GATC) and Earth Insight paints a stark picture of how extractive industries, deforestation, and climate change are converging to endanger the world’s last intact tropical forests and the Indigenous Peoples who protect them.
President Prabowo Subianto welcomed his counterpart Luiz Inacio Lula da Silva of Brazil to Jakarta recently to strengthen ties between the fast-growing economies.
“Has the world given up fighting climate change?” was a rhetorical question posed recently by the New York Times, perhaps with a degree of sarcasm.
It might look that way, says Christiana Figueres, a founding partner of the nongovernmental organization Global Optimism, “as US president Donald Trump blusters about fossil fuel, Bill Gates prioritizes children’s health over climate protection, and oil and gas companies plan decades of higher production.”
As world leaders prepare to gather in Brazil for COP30 next week, they will convene in the heart of the Amazon -- a fitting location for what must become a turning point in how the world addresses the intertwined crises of climate change and biodiversity loss.
Three decades after the first Climate COP, the multilateral climate process – which was intended to serve as an instrument of justice and a guardian of the planet’s atmosphere – has fallen far short of its goals.
