Abstract

As per the Paris Accord, India committed to reduce carbon emissions' intensity by 33–35 percent of its economy by 2030 compared to 2005 levels. A variety of sectors emit different intensities of Greenhouse Gases and air pollutants and it is not clear whether Greenhouse Gas reductions may automatically lead to reduced air pollution or the other way round. There are huge health hazards associated with air pollution. In India with its vast population base, it is more important to curb air pollution than to focus more on Greenhouse Gas emissions policies. In our study, we model the impact of the reduction of Greenhouse Gases based on Paris Accord commitments as well as air pollutants in India. From this analysis, we infer the economic mechanisms that determine the potential complementarities and conflicts involved in reducing Greenhouse Gases and air pollutants, and thereby arrive at nuanced policy implications for the environment in India.

摘要

根据《巴黎协定》，印度承诺到 2030 年将其经济的碳排放强度与 2005 年的水平相比降低 33-35%。不同部门排放的温室气体和空气污染物的强度不同，目前尚不清楚温室气体减排是否会自动导致空气污染减少或反之亦然。空气污染会带来巨大的健康危害。在人口众多的印度，控制空气污染比更多地关注温室气体排放政策更重要。在我们的研究中，我们根据巴黎协议承诺以及印度的空气污染物对减少温室气体的影响进行了建模。从这个分析来看，
