The deployment of carbon dioxide removal (CDR) needs to be scaled up to achieve net zero emission pledges. In this paper we survey the policy mechanisms currently in place globally to incentivise CDR, together with an estimate of what different mechanisms are paying...
The concept of net-zero carbon emissions has emerged from physical climate science. However, it is operationalized through social, political and economic systems. We identify seven attributes of net zero, which are important to make it a successful framework for...
The European Union is debating whether to include carbon dioxide removal (CDR) as part of its 2030 targets on the road to climate neutrality by 2050. In our view, creating sustainable CDR could allow delivery of negative emissions at scale after 2030.
We introduce the carbon takeback obligation (CTBO), a supply-side mitigation policy requiring extractors and importers of fossil fuels to recapture and store a progressively increasing fraction of the CO2generated by their activities and products, and use a novel...
