At the COP28 climate meeting, nearly 200 countries agreed to reduce fossil fuel consumption to mitigate climate change, signaling the end of the oil age.

The accord, reached after two weeks of intense discussions, was intended to show investors and policymakers that the world is united in its determination to abandon fossil fuels, which scientists say is the last chance to prevent climate catastrophe.

COP28 President Sultan al-Jaber termed the pact “historic” but said its implementation will determine its success.

Countries applauded the pact for achieving what decades of climate discussions had failed to do.

However, OPEC, led by Saudi Arabia, insisted the world can cut emissions without banning specific fuels, extending the summit to Wednesday and raising concerns that negotiations might stall.

The accord requires governments to triple renewable energy capacity worldwide by 2030, expedite coal reduction, and accelerate carbon capture and storage to clean up hard-to-decarbonize industries.
