We develop an alternative input–output approach and apply it to the determination of key sectors in emissions. This methodology allows us to assess and classify the different productive sectors according to their greenhouse gas emissions and the role that they play in the productive structure, as well as the participation of their output in the total volume of production. In contrast with previous approaches, we do not focus on the responsibility of final demand, but on the responsibility of the total production of each sector. We apply our methodology to the 2014 input–output table for Spain provided by the World Input–Output Database (2016). The results show that the sectors that induce more emissions from other sectors are manufacture of food products, wholesale and retail trade, and construction. Those that are pulled to emit coincide with those that are relevant for their own final demand, being the most important electricity and gas provision, agriculture, and transportation. The classification obtained allows to orient the design of greenhouse gas emission mitigation policies for the different sectors.

西班牙温室气体排放的关键部门：替代性投入产出分析

我们开发了一种替代性的投入产出方法，并将其应用于确定排放中的关键部门。这种方法使我们能够根据不同的生产部门的温室气体排放及其在生产结构中的作用以及它们的产出在总生产量中的参与度来对不同的生产部门进行评估和分类。与以前的方法相反，我们不关注最终需求的责任，而是关注每个部门的总产量的责任。我们将方法应用于世界投入产出数据库（2016年）提供的2014年西班牙投入产出表。结果表明，导致其他部门排放更多的部门是食品制造，批发和零售贸易以及建筑。被拉动排放的那些与与其最终需求相关的那些相吻合，这是最重要的电力和天然气供应，农业和运输。所获得的分类可以使针对不同部门的温室气体减排政策的设计有针对性。
