We are a mission-driven organisation advancing research on high impact climate repair projects that can be rolled out at scale within the next 5-10 years.

Vision and Mission

Our vision is a pathway to a sustainable future for mankind in tackling the root causes of climate change and ensuring we limit the amount of overshoot.

Our mission is threefold: Reduce CO2 emissions, Remove excess CO2 from the atmosphere, and Refreeze the Arctic.

What We Do

The centre acts as a global coordinating hub for research projects into areas covered by: Reduce emissions, Remove greenhouse gases, and Refreeze the Arctic (the 3 Rs.) We build international consortiums and coordinate research to advance projects from basic research to full-scale deployment. The research projects we support are potential tools for repairing the climate system. Our objective is to advance research so the world has a clear idea of the costs, benefits, and risks of using each approach. As the climate continues to change due to human intervention, the techniques and approaches necessary to repair the climate may change as well. We work to establish a suite of well-researched, ready to use methods to repair the climate, that can be applied as needed.

High Impact

The projects we support are those that have the potential to remove at least 1 Gigaton of CO2 from the atmosphere per year, or have an equivalent impact on the climate.

Rolling out at scale

We envision each project to potentially be applied at such a scale to have a high impact. Applying climate repair at scale means working with affected communities, governments, and world leaders on policy and social acceptability. We require participation from industry to scale-up and permission from international bodies to deploy. Each research project considers these aspects as a critical component.


Advancing scientific research in a particular field takes time, often decades. With an ever changing climate caused by human intervention, and millions experiencing the negative effects such as floods and fires, we do not have the luxury to wait. By prioritising projects and coordinating efforts world-wide, we address the key issues for each research project and prepare for potential application within 5-10 years. 

The Action We Need

  • Time is running out: the level of atmospheric CO2 is now too high for safety.
  • CO2 takes hundreds of years to clear from the atmosphere, so it’s no longer enough just to stop emitting it, and action can’t wait until we reach zero emissions (which many nations have committed to do by 2050 or 2060).
  • We must urgently research ways to take CO2 out of the atmosphere safely.
  • We must also urgently research ways to repair damaged parts of the climate system – e.g., how do we refreeze the poles?

The regulatory, policy and fiscal frameworks needed

  • To facilitate the development of greenhouse gas removal and climate repair techniques, significant research funding is required.
  • Incentives such as carbon pricing are needed to make the development of such industries commercially attractive.
  • International targets for greenhouse gas removal are needed to drive rapid development and deployment of these techniques and technologies

Why the Centre for Climate Repair

  • The Centre for Climate Repair (CCR) is the only Cambridge centre focused on repair and removal, and acts as a hub to bring together academics, researchers and relevant businesses from around the world to collaborate on research and innovation.
  • The Centre for Climate Repair was founded and chaired by Sir David King in 2019 and was incubated at Downing College. In 2023 the Centre moved to the Department of Applied Mathematics and Theoretical Physics and the board is now chaired by Prof Nigel Peake.
