BERLIN: Researchers say efforts to remove carbon dioxide from the atmosphere are not being scaled up fast enough and cannot be relied on to meet crucial climate goals.
New carbon removal technologies include so-called direct air capture, where CO2 is sucked from the atmosphere and stored underground. Another method known as biochar involves burning plant matter and then burying the carbon-heavy waste. Achieving ‘net zero’ emissions by mid-century — a goal many countries are aiming for and experts say is necessary to meet the targets agreed in the 2015 Paris climate accord — would require an increase in carbon dioxide removal by a factor of 1,300 and few countries have realistic plans for doing so, the authors said.
Oliver Geden of the German Institute for International and Security Affairs, who also contributed to the report, said natural means of carbon removal, such as reforestation, are currently more cost-effective than artificial methods.
