印度是世界上大气汞排放量最大的国家之一。印度的生产活动与汞排放有关，汞排放可归因于最终需求（例如，家庭、政府和私人投资的购买）从需求角度推动上游生产的国家，或主要投入（例如，劳动力和资本供应）的国家，使下游生产从供应的角度来看。本研究从需求和供应两个角度确定了2004-2014年期间直接和间接推动印度汞排放的主要国家和部门。虽然从需求角度来看，国内最终需求是主要驱动力（占总量的80-85%），但美国，中国和阿联酋是重要的外国驱动力。同样，从供应角度看，国内初级投入是主要驱动力。然而，在这十年中，导致汞排放的外国投入所占份额从16%增加到23%。沙特阿拉伯、印度尼西亚、澳大利亚和中国是最大的外国供应方驱动力。建筑部门是重要的需求方驱动力，而化石燃料部门是重要的供应方驱动力。这些研究结果可以指导印度汞排放需求和供应方管理的全球和国家政策，并有助于成功实施《关于汞的水俣公约》。
India is among the largest emitters of atmospheric mercury (Hg) in the world. India's production activities have associated Hg emissions which can be attributed to final demands (e.g., purchases by households, governments, and private investments) of nations driving upstream production from the demand perspective, or primary inputs (e.g., labor and capital supply) of nations enabling downstream production from the supply perspective. This study identifies key nations and sectors that directly and indirectly drove India's Hg emissions from both the demand and supply perspectives during 2004-2014. While domestic final demand was the dominant driver from the demand perspective (driving about 80-85% of the total), USA, China, and UAE are important foreign drivers. Similarly, from the supply perspective, domestic primary inputs were the dominant drivers. However, the share of foreign inputs enabling Hg emissions increased from 16 to 23% during the decade. Saudi Arabia, Indonesia, Australia, and China are the top foreign supply-side drivers. The Construction sector is an important demand-side driver, whereas fossil fuel sectors are important supply-side drivers. These findings can guide global and national policies for demand- and supply-side management of Hg emissions in India and assist in the successful implementation of the Minamata Convention on Mercury.
