CO2 Emissions vs. CO2 Responsibility: An Input-Output Approach for the Turkish Economy
G. Ipek Tunc, Serap Turut-Asik and Elif Akbostanci,
Recently, global warming (greenhouse effect) and its effects have become one of the hottest topics in
the world agenda. There have been several international attempts to reduce the negative effects of global
warming. Kyoto Protocol can be cited as the most important agreement which tries to limit the countries’
emissions within a time horizon. For this reason it becomes important to calculate the greenhouse gas
emissions of countries. The aim of this study is to estimate the amount of CO2 -the most important greenhouse
gas- emissions, for the Turkish economy. An extended input-output model is estimated by using 1996 data in
order to identify the sources of CO2 emissions and to discuss the share of sectors in total emission.
Besides ‘CO2 responsibility’, which takes into account the CO2 content of imports, is estimated for the
Turkish economy. The sectoral CO2 emissions and CO2 responsibilities are compared and these two notions
are linked to foreign trade volume. One of the main conclusions is that the manufacturing industry has
the first place in both of the rankings for CO2 emissions and CO2 responsibilities; while agriculture and
husbandry has the last place.
