碳的社会成本(SCC)是理解和实施气候变化政策的核心概念。这个术语表示额外排放一吨二氧化碳或其等价物所造成的经济成本。本研究提出了基于修订的DICE模型(气候与经济动态综合模型)的最新估计。该研究估计,2010年每吨二氧化碳的SCC为31美元,按当期(2015年)计算。对于中心案例,到2050年,实际SCC以每年3%的速度增长。论文还将这些估计与其他来源的估计进行了比较。
The social cost of carbon (SCC) is a central concept for understanding and implementing climate change policies. This term represents the economic cost caused by an additional ton of carbon dioxide emissions or its equivalent. The present study presents updated estimates based on a revised DICE model (Dynamic Integrated model of Climate and the Economy). The study estimates that the SCC is $31 per ton of CO2 in 2010 US$ for the current period (2015). For the central case, the real SCC grows at 3% per year over the period to 2050. The paper also compares the estimates with those from other sources.
