As the world faces severe climate challenges like heatwaves, floods, and food shortages, global leaders gathered for the 30th Conference of the Parties (COP30) in Belém, Brazil, from November 10 to 21, 2025.
The main goal of COP30 was to ramp up climate action and ensure that countries deliver on the Paris Agreement. This agreement aims to keep global temperature rise well below 2°C and ideally limit it to 1.5°C. Each nation must submit a plan called a Nationally Determined Contribution (NDC) to show how it will cut greenhouse gas emissions and adapt to climate impacts.
Despite recent slowdowns in emissions growth, COP30 was a crucial moment to tackle the gap between what countries promised and what they actually do. By the conference’s end, countries committed to significantly increase climate finance for developing nations, focusing on tripling support for projects that help both mitigate and adapt to climate change.
At the opening, UN Climate Change Executive Secretary Simon Stiell pointed out the enormous risks of delays in climate action. “We need solutions,” he said. Stiell highlighted that although there are signs of progress, like slowing emissions growth, we still need to do more to meet the 1.5°C target.
He compared effective climate action to a river system, saying, “We must have many streams of cooperation. Individual national commitments alone aren’t cutting emissions fast enough.” Some regions are experiencing economic losses due to climate-related disasters, which affect GDPs, agriculture, and poverty.
Transitioning to renewable energy is now economically logical. Solar and wind energy have become the cheapest sources of electricity in 90% of the world. By the end of 2025, investments in clean energy are expected to surpass those in fossil fuels twofold. COP30 aims to operationalize agreements to boost renewable energy capacity and efficiency while delivering at least $300 billion in climate finance, led by developed countries.
Nigeria reaffirmed its commitment to climate action. At COP30, they emphasized their green transition, focusing on renewable energy, sustainable agriculture, and better waste management. Nigeria aims to cut emissions by 32% by 2035 and is implementing frameworks to support this transition.
Prof. Magnus Onuoha from the West Africa Green Economic Development Institute noted that Nigeria’s policies are well-structured for scaling up wind energy. The country’s Electric Power Sector Reform Act set the stage for private sector involvement, and laws like the Renewable Energy Master Plan and the Climate Change Act have ramped up the adoption of renewables.
At COP30’s conclusion, UNEP Executive Director Inger Andersen announced the launch of the Tropical Forest Forever Facility, valued at $6.7 billion, to support significant actions for cutting methane emissions and protecting forests.
Unprecedented participation from Indigenous Peoples and various organizations showed that momentum for climate action goes beyond formal negotiations. According to Andersen, COP30 reinforced the idea that the Paris Agreement is achieving results, with calls to triple adaptation finance by 2035 and create just transition mechanisms for inclusive growth.
As the world moves forward, the focus shifts from pledges to actual performance. The new commitments from Belém set ambitious benchmarks for finance, energy transitions, and forest protection. However, the real test will be whether these plans turn into measurable actions that have a real impact on climate change.
