The carbon intensity of human well-being (CIWB) is an effective indicator for measuring the progress of the UN Sustainable Development Goals. Compared with production-based accounting, consumption-based CIWB is more useful for the dual tasks of improving cost-effectiveness and increasing equity. Therefore, this study for the first time estimated consumption-based CIWB in 176 countries from 1990 to 2015 by a multi-region input-output model and explored its spatiotemporal patterns. A panel regression technique was adopted to test the impact of the potential socio-economic determinants, with consideration given to the income levels of global countries. We found that global consumption-based CIWB improved annually between 1990 and 2015, and the gap between countries has also gradually decreased since 1995. Apparent differences in consumption-based CIWB and its changes were observed in the four income groups. The lower the income, the more pronounced the trend of consumption-based CIWB reductions was. Economic growth, energy intensity, and exports of goods and services all have a negative impact on the consumption-based CIWB, i.e., elevated CIWB values, while population density, urbanization, renewable energy consumption, and imports of goods and services all lower CIWB values. The effect of socioeconomic factors on consumption-based CIWB also presented different changes depending on income levels. The results of the study provide an important reference for improving the environment while enhancing human well-being.

全球各国基于消费的人类福祉碳强度及其社会经济驱动因素

人类福祉的碳强度(CIWB)是衡量联合国可持续发展目标进展情况的有效指标。与基于生产的会计相比,基于消费的CIWB对于提高成本效益和增加公平的双重任务更有用。因此,本研究首次通过多区域投入产出模型估算了 176 个国家 1990 年至 2015 年基于消费的 CIWB,并探讨了其时空格局。面板回归技术被采用来测试潜在的社会经济决定因素的影响,同时考虑到全球国家的收入水平。我们发现,1990年至2015年间,全球以消费为基础的CIWB逐年提高,自1995年以来,各国之间的差距也逐渐缩小。在四个收入组中,以消费为基础的CIWB及其变化存在明显差异。收入越低,基于消费的CIWB减少趋势越明显。经济增长、能源强度、商品和服务出口都对基于消费的CIWB产生负面影响,即CIWB值升高,而人口密度、城市化、可再生能源消费和商品和服务进口均降低CIWB值. 社会经济因素对基于消费的CIWB的影响也随着收入水平的不同而呈现出不同的变化。研究结果为改善环境、增进人类福祉提供了重要参考。
