Caldecott & Johnstone (2024): The Carbon Removal Budget: theory and practice
Ben Caldecott, Injy Johnstone IN: Carbon Management, 15, https://doi.org/10.1080/17583004.2024.2374515
There are ongoing questions as to how we can increase the supply of quality CDR whilst at the same time ensure equitable distribution of that same CDR, both within and between countries and non-state actors. To explore these phenomena, the authors introduce and define the concept of a Carbon Removal Budget (CRB), illustrate how it can apply to different contexts and scales, and distinguish it from the related but distinct concept of the carbon budget. They further estimate the global CRB, review its constraints and quality considerations and outline potential utilisation pathways and principles. They then examine the potential application of the CRB as a tool on which both public and private decision-makers can use to assess the feasibility of their nationally determined contributions and/or net-zero transition plans.
