Abstract
This is the first study quantifying both direct and indirect emission burdens on the environment from households in the Czech Republic. Indirect emissions are released during the manufacture and distribution of goods consumed by the households, while direct emissions stem from the fuels burnt in homes or to propel cars.
Emissions of greenhouse gases, gases causing acidification and substances giving rise to photochemical smog attributable to the household consumption are taken into account. To assign the indirect emissions to the particular product group, linkages between detailed household final expenditure categories and industry product groups are made.
The Multiregional Environmentally Extended Input-Output Analysis based on the CREEA database in combination with Single Region Input-Output Analysis using national NAMEA and symmetrical input-output tables are used to calculate the indirect emission values in such a way to take advantage of the strengths of both databases in order to get the most precise results possible. Among product categories, a major part of GHG emissions is stemming from demand on electricity and heat, while food contributes mostly to SO2eq emissions and transport is mostly responsible for emissions causing photochemical smog.
Resulting emissions are aggregated to 7 groups: food, housing, heating and hot water, electricity, transportation, goods and services so the relevant policies can be suggested. The households are then grouped into deciles according to their expenditures and their emission elasticity of expenditures is calculated.
