2015年12月达成的《巴黎协定》，是全球应对气候变化里程碑式的成果，将把21世纪内全球平均温升幅度控制在2℃以内设为全球减排目标。多数2℃目标下的减排模式需要从21世纪中叶开始大规模应用能带来“负排放”的BECCS技术。本文整理介绍了BECCS的技术概念，其进入气候变化综合评估模型（IAMS）和减排情景的历程及其全球示范项目的发展现状；探讨了BECCS技术所面临的主要挑战和不确定性；并指出若无革命性的技术突破、足够的政策和资金支持，在可预见的未来，BECCS技术几乎没有可能发展成为一种能帮助实现《巴黎协定》目标的关键技术。
The Paris Agreement，a landmark achievement of climate change negotiation，reached in December 2015，set 2℃ target of average global temperature increase control by the end this century. Most mitigation scenarios under 2℃ target require large-scale deployment of BECCS，a technology that is alleged to bring “negative emissions”，by 2050. By reviewing the inclusion of BECCS in IAMs and emission scenarios and current development status of BECCS demonstration projects，this paper discussed major challenges and contingencies of the development of BECCS，and pointed out that without major technological breakthrough or sufficient funding，the chance of developing BECCS into a key technology for realizing 2℃ target is slim.
