Resum:

Analysis of gas emissions by the input-output subsystem approach provides detailed
insight into pollution generation in an economy. Structural decomposition analysis, on
the other hand, identifies the factors behind the changes in key variables over time.
Extending the input-output subsystem model to account for the changes in these
variables reveals the channels by which environmental burdens are caused and
transmitted throughout the production system. In this paper we propose a decomposition
of the changes in the components of CO2 emissions captured by an input-output
subsystems representation. The empirical application is for the Spanish service sector,
and the economic and environmental data are for years 1990 and 2000. Our results show
that services increased their CO2 emissions mainly because of a rise in emissions
generated by non-services to cover the final demand for services. In all service
activities, the decomposed effects show an increase in CO2 emissions due to a decrease
in emission coefficients (i.e., emissions per unit of output) compensated by an increase
in emissions caused both by the input-output coefficients and the rise in demand for services. Finally, large asymmetries exist not only in the quantitative changes in the
CO2 emissions of the various services but also in the decomposed effects of these
changes.
Keywords: structural decomposition analysis, input-output subsystems, CO2 emissions,
service sector. |
