More than 190 governments at the United Nations climate conference approved an agreement Wednesday calling for the world to transition away from fossil fuels, sending an unprecedented signal to the global economy that governments are intent on cutting back on coal, oil and natural gas in the fight against global warming.

The deal, the result of all-night talks, calls for “transitioning away from fossil fuels in energy systems, in a just, orderly and equitable manner.” It says the shift to clean energy for the global economy should accelerate this decade with the aim of net-zero greenhouse gas emissions by 2050. Scientists say that is crucial to fulfilling the Paris accord, the landmark climate agreement that calls for governments to attempt to limit global warming to 1.5 degrees Celsius above preindustrial temperatures. 

“We should be proud of our historic achievement,” said Sultan Al Jaber, the chief executive of the United Arab Emirates’ national oil company who is running COP28, in a closing address that garnered a standing ovation from many delegates. “We have delivered a robust action plan to keep 1.5 within reach.”
