| 英文摘要: | Modelling of the power system on the west coast of North America shows that including bioenergy with carbon capture and sequestration technologies could enable the region to be carbon negative by 2050. Investigating decarbonization pathways is a key component of informing policymakers and society about the potential for mitigating climate change. Several model-based studies have explored decarbonization scenarios for national, regional and global power sectors1, 2. However, although the need to include negative CO2 emissions in such analyses has been recognized in global energy sector studies, few national or regional models have included negative-emission technologies3, 4. Writing in Nature Climate Change, Daniel Sanchez and colleagues present findings that are of interest far beyond the boundaries of the power sector in the west coast region of North America that they studied5. The authors map out the potential for the area's CO2 emissions to be reduced by 2050, including what would be required to achieve net negative levels.

Agricultural biomass residues make the west coast of North America a prime candidate region for using bioenergy use with carbon capture and storage (BECCS) to reduce CO2 emissions.
