What we do

Practical solutions for our changing planet

Humanity must reach net-zero greenhouse gas emissions by mid-century to avoid disastrous climate change. The earlier this is achieved, the greater our chance of limiting global temperature rise to near 1.5°C, helping prevent runaway climate change.

All emissions that can go to zero must go to zero – as rapidly as possible. Not just from electricity, but also from heat, transport, industry and land-use.

We have the tools to do it. CAT’s Zero Carbon Britain research clearly demonstrates that we already have all the technologies we need to achieve zero carbon emissions by 2050 – or even earlier.

“Every bit of extra warming makes a difference.” Hans-Otto Pörtner, Intergovernmental Panel on Climate Change (IPCC)

Action is required at all levels: individuals, communities, businesses and government. We need people with the skills, knowledge and understanding to make change happen.

And we must act now.

Inspire, inform, enable

CAT’s mission is to inspire, inform and enable humanity to respond to the climate and biodiversity emergency.

CAT is an educational charity dedicated to researching and communicating positive solutions for environmental change.

We speak to government and campaigners about policies that would help create a zero carbon Britain; we train students in all aspects of sustainability; we help schoolchildren to understand the importance of action on climate change; and we give advice to householders on what they can do in their own homes.

Will you help create change?

“The decisions we make today are critical in ensuring a safe and sustainable world for everyone, both now and in the future.” Debra Roberts, IPCC

We need people like you who care about the world and all those who share it to help make change happen.
