Research
The Centre for Climate Repair works across disciplines at the University of Cambridge and in collaboration with organisations all over the world. We are investigating potential approaches to complement emissions reduction that could be scalable and effective in the next few decades. Each of our themes is undergoing rigorous scientific testing to help us better understand its feasibility and risks.
Removing greenhouse gases
Kelp
Our researchers are studying the rate of biomass growth and carbon export to better understand kelp's potential to sequester carbon dioxide.
Marine biomass regeneration
We’re exploring a novel approach to add nutrients to the ocean to stimulate phytoplankton, which naturally sinks into the deep ocean and carries carbon away from the climate system.
Direct air capture
Researchers are developing low-cost sorbents that could help address the financial and energy costs of direct air capture (DAC).
Methane oxidation
Our researchers are developing photochemical filter systems designed for integration into HVAC units, offering a dual benefit: improving indoor air quality and enabling the removal of atmospheric methane.
SEAO2-CDR
SEAO2-CDR is a collaboration funded by the EU's Horizon Europe research and innovation programme. It aims to establish and evaluate the mechanisms and processes required to ensure the environmentally safe, socially acceptable and economically viable implementation of appropriate ocean-based CDR approaches in support of global climate policies.
Refreezing the Arctic
Sea ice thickening
Field trials and modelling of approaches to thicken Arctic sea ice - to potentially slow summer melt, reduce Arctic warming, and mitigate further ice loss.
Marine cloud brightening
Brightening marine clouds using seawater to enhance their reflectivity and reduce sunlight warming the oceans.
Stratospheric aerosol injection
Testing materials and technology that could be used in the stratosphere to reflect sunlight back into space.
Public perceptions
Using big data, researchers are studying public perceptions of solar geoengineering and mapping connections to related issues and ideologies. Topics include conspiracy spillovers, political ideology, and attention.
Participatory governance
This research looks at participatory mechanisms and the role they play in the construction of a fair governance framework for solar geoengineering technologies.
