研究表明,碳的社会成本应该超过280美元,超过美国目前估计值的两倍以上。 Study suggests the social cost of carbon should be over $280, more than double current U.S. estimates.

加利福尼亚大学戴维斯的一项研究表明,目前对碳(SCC)社会成本的估计太低。 A study from the University of California, Davis, suggests that current estimates for the social cost of carbon (SCC) are too low. SCC衡量每排放一吨CO2造成的经济损害。 The SCC measures the economic damage caused by each ton of CO2 emitted. 该研究报告发表在PNAS中,它声称SCC应超过每吨二氧化碳280美元,比美国环保局目前估计的190美元高出一倍多。 The study, published in PNAS, claims the SCC should be over $280 per ton of CO2, more than double the current U.S. EPA estimate of $190. 这一更高的成本突出表明,需要采取更严格的政策,减少温室气体排放,减轻气候变化的影响。 This higher cost underscores the need for stricter policies to reduce greenhouse gas emissions and mitigate climate change impacts.
