Environmental Impact Assessment of Household Consumption

Summary We analyze the environmental impact of household consumption in terms of the material, water, and land‐use requirements, as well as greenhouse gas (GHG) emissions, associated with the production and use of products and services consumed by these households. Using the new EXIOBASE 2.2 multire...

Shrnutí:Summary We analyze the environmental impact of household consumption in terms of the material, water, and land‐use requirements, as well as greenhouse gas (GHG) emissions, associated with the production and use of products and services consumed by these households. Using the new EXIOBASE 2.2 multiregional input‐output database, which describes the world economy at the detail of 43 countries, five rest‐of‐the‐world regions, and 200 product sectors, we are able to trace the origin of the products consumed by households and represent global supply chains for 2007. We highlight the importance of environmental pressure arising from households with their consumption contributing to more than 60% of global GHG emissions and between 50% and 80% of total land, material, and water use. The footprints are unevenly distributed across regions, with wealthier countries generating the most significant impacts per capita. Elasticities suggest a robust and significant relationship between households’ expenditure and their environmental impacts, driven by a rising demand of nonprimary consumption items. Mobility, shelter, and food are the most important consumption categories across the environmental footprints. Globally, food accounts for 48% and 70% of household impacts on land and water resources, respectively, with consumption of meat, dairy, and processed food rising fast with income. Shelter and mobility stand out with high carbon and material intensity, whereas the significance of services for footprints relates to the large amount of household expenditure associated with them.
Bibliografia:Supporting Information S1: This supporting information provides information about household environmental footprints including total and per capita absolute values across countries and RoW regions and consumption categories; information about total household expenditure, population, and national GDP (purchasing power parity; PPP); version of figure 2 depicting all 43 countries; and further description of the database.
