Jenkins, Stuart et al. (2021): Upstream decarbonization through a carbon takeback obligation: An affordable backstop climate policy

Stuart Jenkins, Eli Mitchell-Larson, Matthew C. Ives, Stuart Haszeldine, Myles Allen IN: Joule (2021),

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 CO2 generated by their activities and products, and use a novel integrated assessment model (IAM) emulator to compare this policy to conventional demand-site mitigation policy. A global CTBO is shown to be comparable in cost to similar ambition scenarios dominated by demand-side measures simulated by a global carbon price.
