This report describes the database PEACH2AIR, which calculates air pollution linked to con- sumer expenditures in Belgium in 2014. The considered pollutants are greenhouse and acidifying gases, gases contributing to tropospheric ozone formation and particulate matter. This air pollution is calcu- lated at the consumption stage, i.e. the use of energy products by households, and at the production stage, i.e. the air pollution caused by the production of the goods and services purchased by households. To do this, PEACH2AIR relies on internationally standardized air pollution data (including air emis- sions accounts of the Federal Planning Bureau), input-output tables and the House-hold Budget Survey. Analyses for 2014 show that energy products, as well as food and non-alcoholic beverages, were the most air polluting expenditure categories.
