About climate change

Climate change is the greatest environmental threat humanity has ever faced and the biggest challenge. Climate change is caused by the build up of greenhouse gases - from burning fossil fuels and the destruction of areas that store massive amounts of carbon like the world's rainforests. No one knows how much warming is “safe” but we know that climate change is already harming people and ecosystems around the globe.

We're campaigning for climate solutions that still allow people to prosper without damaging the planet including increasing energy efficiency, clean energy and protecting the world's rainforests.

The causes


What you can do about climate change

We can stop catastrophic climate change. We know what causes it, we have the technologies to prevent it, and there's a rapidly growing understanding of just how urgent the need for action is.

All that's missing is the action itself.

The government needs to put in place meaningful policies to urgently reduce emissions - and to act on them immediately. We need your help to persuade them. Together, we can stop climate chaos.
