The transition to natural refrigerants offers a viable way forward, but there is an urgent need for legislative action and improved regulations to accelerate it. This would help reduce dangerous PFAS pollution, and reduce emissions at the same time, a win for both health and the environment.
The sad truth is that the refrigerant gases helping us adapt to climate change are themselves a leading driver of the crisis. Effective rules and enforcement is needed to keep this sleeping giant of a climate threat on ice.
