Over-reliance on land for carbon dioxide removal in net-zero climate pledges

K. Dooley, K. L. Christiansen, et al.

This research reveals that approximately 1 billion hectares of land are needed for carbon dioxide removal as part of national climate pledges, with a significant portion involving land-use change. Conducted by Kate Dooley, Kirstine Lund Christiansen, Jens Friis Lund, Wim Carton, and Alister Self, the findings emphasize the critical need for transparency in climate commitments.

Abstract
This paper examines the land requirements for carbon dioxide removal (CDR) implied in national climate pledges. The authors find that pledges require approximately 1 billion hectares of land for removals, with over 40% involving land-use change. This highlights a significant gap between expected reliance on land-based CDR and its realistic potential, underscoring shortcomings in national climate pledges and the need for greater transparency.
