Natural carbon uptake by ocean biology will not deliver credible carbon credits

by Emily Cracknell | Nov 5, 2025

Natural CO2 removal is increasingly being claimed as anthropogenic climate mitigation. This misrepresentation is already prevalent for forests and coastal ecosystems; there is now the risk of the error reoccurring for open-ocean CO2 uptake via the biological carbon...

Countries need to provide clarity on the role of carbon dioxide removal in their climate pledges

by Helen Bunting | Nov 22, 2024

Carbon dioxide removal (CDR) involves capturing CO2 from the atmosphere and storing it for decades to millennia. Alongside deep emissions reductions, CDR is required for meeting the temperature goal of the Paris Agreement (IPCC 2022). However, parties to the agreement...

Public attitudes and emotions toward novel carbon removal methods in alternative sociotechnical scenarios

by Helen Bunting | Jul 16, 2024

Despite high expectations about the role of carbon removal in meeting global climate targets, many of the proposed techniques remain nascent. This is especially so for techniques with potential for large-scale, permanent removal of CO2, such as direct air carbon...

Editorial: Decision making for net zero transformation considerations and new methodological approaches

by Emily Cracknell | Jan 22, 2024

Members of the editorial team for this special edition have been engaging in an ongoing dialogue with the Clean Air Task Force (CATF) around the dominant decision support and decision-making orthodoxy for the net zero transformation since 2020. It was and has become...

Comparing approaches for carbon dioxide removal

by Emily Cracknell | Sep 28, 2022

Alternatively known as greenhouse gas removal (GGR), carbon dioxide removal (CDR), or negative emissions technology (NET), the concept of removing greenhouse gases (GHGs)—primarily CO2—from the atmosphere has been gaining increasing academic, industrial, financial,...
