Traditional carbon removal methods like planting trees and restoring wetlands are part of this mix, as are more novel options like biochar and technologies that directly capture and store carbon. For example, some carbon removal methods depend on significant energy consumption and require vast tracts of land. Caldecott added, 'The Carbon Removal Budget is the cumulative amount of carbon removal available to realise global temperature goals. Critically, how should we allocate the finite, even if growing, carbon removal supply between different countries, companies, and financial institutions? 'Embedding carbon removal budgets into decision-making is necessary for an effective response to climate change.
