As the UN Climate Change Conference was happening in Brazil, the Trump administration released proposals to open up offshore drilling and roll back protections for wetlands and endangered animals.

By Kate Abnett, Lisandra Paraguassu, William James and Sudarshan Varadhan BELEM, Brazil (Reuters) -The outcome of Brazil's COP30 climate summit was left hanging in the balance, with the European Union refusing to accept a draft deal it said would fail to advance global efforts to curb greenhouse gas emissions driving climate change.

The U.S. is maintaining a presence at COP30, despite the Trump administration declining to send an official delegation to this year's climate conference in Brazil.

While delegates at a U.N. conference discussed how to fulfill past promises on fighting climate change, a boisterous gathering focused on the same topic from a very different perspective was taking shape.

The Trump administration sent nobody to the U.N. global climate summit, leaving California Governor Gavin Newsom to ask, "What the hell is going on here?"

The conference is being led by COP30 president André Corrêa do Lago, Brazil’s vice minister for climate, energy and environment at the Ministry of Foreign Affairs. Among those scheduled to attend are government leaders and ministers, diplomats, U.N. representatives, scientists, business leaders and non-governmental organizations across the globe.

As leaders meet in Belém, see what Iran, one of the world’s top ten carbon emitters, said about its plans to tackle climate change at COP30.

This year's COP30 summit in Belem, Brazil, highlighted food, forests and land as key topics to be addressed. One sector that crosses across all these is agriculture, which is responsible for about one-third of global carbon emissions.
