牛津大学：2026年二氧化碳去除现状：全球独立的二氧化碳去除科学评估报告（第三版）（英文版）

Both carbon dioxide removal (CDR) and emissions reductions are needed to reach the Paris temperature goal. CDR consists of human activities capturing CO2 from the atmosphere and storing it durably in geological, terrestrial or ocean reservoirs, or in products. For as long as any emissions continue, CDR will be needed to halt the rise in global temperature. All scenarios that reach net zero and halt the rise in global temperature deploy additional CDR at gigatonne scale. Across costeffective s
