  • Countries adopted the first-ever climate deal that calls for a transition away from fossil fuels.
  • The deal also calls for the world to triple renewable energy by 2030.
  • The deal caps another UN climate summit in Dubai with big promises that have yet to be delivered.

Nearly 200 countries on Wednesday reached a historic climate deal calling for the transition away from fossil fuels starting this decade and the tripling of renewable energy by 2030.

The deal marks the first time that countries addressed the leading cause of the climate crisis – burning coal, oil, and gas – and set a global target for boosting renewables like solar and wind power. Past UN climate agreements have mostly avoided fossil fuels.
