Abstract< /p>

The international co mmunity aims to limit global warming to "\;well-below"\; 2°C and possibly to 1.5°C\, but little progress has been made towards a global\, cost-efficient\, and fair climate action plan to deploy the carbon dioxide removal (CDR) required to reach these objectives. Here\, we investigate h ow a portfolio of CDR solutions —\; afforestation/reforestation (AR)\ , bioenergy with CCS (BECCS)\, and direct air carbon capture and storage ( DACCS) —\; might be deployed to meet the Paris Agreement’\;s CDR objectives. We find that international cooperation is key for deploying t he most cost-efficient CDR pathway —\; comprised primarily of BECCS ( 78%) and AR (22%) —\;\, as it allows to take the most advantage of lo cation/national context and time variations\, and thus minimise costs. Importantly\, the spatio- temporal evolution of this CDR pathway differs greatly from the regional a llocation of these CDR objectives —\; resulting from the responsibili ty-based burdensharing principle\, used here as a proxy for their fair distribution. With limited\, or no international co operation\, we find that delivering these CDR objectives proves to be sign ificantly more challenging. Key domestic bio-geophysical resources include geological CO2 sinks\, of which the absence\, or lack of identification\, undermines the feasibility of these CDR objectives\, and land and biomass supply\, of which the limited availability makes them more costly —\ ; specifically when leading to the deployment of DACCS. Moreover\, we show that establishing a market for the international trade of negative emissi ons (NE) achieve simultaneously cost-efficiency and equity in delivering C DR at the Paris Agreement’\;s scale\, by incentivi sing all nations to meet their share of the Paris Agreement’\; s CDR objectives whilst making up for the uneven distribution of bio-geoph ysical resources across the world. Crucially\, we argue that there is limi ted time left to develop a global geopolitical and economic framework\, in cluding not only such international NE trading market but also robust inst itutions to monitor\, verify and accredit its efficiency and equity. We co nclude that international cooperation in the very near-term is imperative to ensure that the feasibility and sustainability of CDR pathways are not compromised\, and that future generations do not bear the increasingly mor e costly burden of climate mitigation inaction.
