The world has delayed reducing carbon emissions for so long that humanity will need to suck enormous amounts of carbon dioxide back out from the air to avoid catastrophic global warming. That’s one of the conclusions of a new report published by the Intergovernmental Panel on Climate Change.
Earlier this year, Environmental Research Letters published three studies reviewing the need for negative emissions and laying out the state of development for the technologies that can help us achieve them. Quartz has synthesized those reports to help you understand the technologies that may be required to capture as much as 20 billion metric tons each year to prevent catastrophic climate change.
The deployment of negative-emissions technologies has to be alongside zero-carbon technologies that displace the use of fossil fuels or abate their emissions. In other words, we will also need more solar, more wind, more nuclear, along with the deployment of more batteries, electric cars, and carbon capture and storage for industries, such as cement, steel, and ethanol.
