Opinion | Cop30: the world’s moment of truth
As the world returns to Brazil to confront climate change, it must be clear that the era of declarations of good intentions has ended and the time for action plans has arrived

Today, in the Brazilian Amazon, the Belem Summit opens ahead of the 30th United Nations Climate Change Conference (Cop30). I have convened world leaders in the days leading up to the Cop30 so that we can all commit to acting with the urgency the climate crisis demands.
If we fail to move beyond speeches into real action, our societies will lose faith, not only in the Cops, but in multilateralism and international politics more broadly. That is why I have summoned leaders to the Amazon: to make this the Cop of Truth, the moment we demonstrate the seriousness of our shared commitment to the planet.
Humanity has shown its ability to overcome great challenges when it acts together and is guided by science. We protected the ozone layer. The global response to the Covid-19 pandemic proved that the world can act decisively when there is courage and political will.
Brazil hosted the Earth Summit in 1992. We approved the conventions on climate, biodiversity and desertification, and adopted principles that defined a new paradigm for preserving our planet and our humanity. Over the past 33 years, these gatherings have produced important agreements and targets for reducing greenhouse gas emissions – from ending deforestation by 2030 to tripling renewable energy use.
More than three decades later, the world returns to Brazil to confront climate change. It is no coincidence that Cop30 takes place in the heart of the Amazon rainforest. This is an opportunity for politicians, diplomats, scientists, activists and journalists to witness the reality of the Amazon.
We want the world to see the true state of the forests, the planet’s largest river basin, and the millions of people who live in the region. Cops cannot be mere showcases of good ideas or annual gatherings for negotiators. They must be moments of contact with reality and of effective action to tackle climate change.
