Consumption-based Greenhouse Gas Emissions Input-Output Model

Using input-output tables, fuel emissions factors and industry fuel requirements, we derive a carbon intensity vector. This carbon intensity vector shows the emissions associated with one dollar of gross output by each industry. There are two carbon intensity vectors derived. One includes and the other excludes process emissions. These are then matched to HES consumption categories to show the emissions associated with one dollar of expenditure. Incorporating household expenditure, we then calculate total household emissions and emissions by consumption category.
