Around the world, Practical Action is working with people to help them adapt to the effects of climate change. We are also helping people to escape poverty by using clean, renewable energy.

And our Stop Climate Injustice campaign calls for urgent UK and international policy to tackle climate change. Find out how you can get involved, and how to make changes in your own lives to reduce our impact on climate change.
