The controversy of carbon geoengineering

Supporters insist removing carbon from the atmosphere is necessary to reach net zero, but critics call it a ‘dirty trick’ from fossil fuel producers

Carbon geoengineering is the removal and durable storage of carbon emissions from the atmosphere aimed at helping to limit the global temperature rise. While carbon dioxide removal technologies could support efforts to reach net zero emissions by 2050, they remain controversial and critics warn that fossil fuel producers could use them to justify business as usual.
