Paris Agreement: a Decade Later

Paris Agreement: a Decade Later
The Paris Agreement, a 2015 accord that altered the trajectory of climate politics, crosses its 10th anniversary with notable strides in clean energy, policy, and emissions. A decade ago, the forecast was dire, projecting a rise to 4°C by 2100, but today we're on a path closer to 2.6°C, thanks to a surge in clean energy deployment and stronger policies. The world has seen solar and wind energy smash expectations, and electric vehicles are now ahead of past forecasts. If there’s one lesson here, it’s that with collaboration, determination, so much is possible. As the 30th UN climate meeting, COP30, approaches, the challenge remains to consolidate this momentum, ensuring benefits reach communities worldwide. While there is still much more work to be done, it's important to acknowledge and celebrate that the clean-energy transition is currently more advanced than analysts projected a decade ago.

Be the Change

Support local clean energy initiatives, or do one small act today that reduces your energy use, such as opting to bike, walk or bus instead of drive.
