摘要: Given the increasing interest in keeping global warming below 1.5°C, a key question is what this would mean for China's emission pathway, energy restructuring, and decarbonization. By conducting multimodel study, we find that 1.5°C-consistent goal require China to reduce its carbon emissions consumption by more than 90 39%, respectively, compared with "no policy" case. Negative technologies play an important role achieving near-zero emissions, captured accounting on average 20% of total reductions 2050. Our comparisons reveal large differences necessary across sectors, whereas consistent power sector required achieve full decarbonization The cross-model averages indicate accumulated policy costs may amount 2.8 5.7% gross domestic product 2050, given 1.5°C limit.
