Stabilising the climate means rapidly slashing emissions. However, scientists say sucking historic emissions out of the air is also vital if we are to keep warming to internationally agreed levels.
A £30m project to do just that was announced in the UK this week. As part of the trial, scientists will test the most effective ways of drawing climate-heating carbon out of the air, including planting trees, re-wetting peatlands and spreading rock chips that absorb CO2 on farmland. It will be one of the world’s biggest carbon capture projects.
“Greenhouse gas removal is not only essential, it also has the potential to become big business,” said Prof Cameron Hepburn, from the University of Oxford, who is coordinating the trials. “As we rebuild societies and economies following Covid-19, we have an opportunity to orient ourselves towards the green jobs and industries of the future.”
