Emissions embodied in Chinese exports taking into account the special export structure of China

Quantification of CO2 emissions embodied in China's trade is important for an informed debate on whom to blame for the recent rise in Chinese emissions or the calculation of border carbon adjustments. Applying input–output (IO) techniques, we calculate these emissions in (1) a standard model, (2) a regionally disaggregated model, taking into account that export production is concentrated in more advanced and more emission efficient provinces and (3) in a model with export processing, taking into account that almost half of the Chinese exports rely on a large share of imported intermediates and little domestic value and emissions added. We compare year 2007 emissions embodied in Chinese exports in a unified framework. We also report emissions embodied in Chinese imports used for intermediate production of exports by combining calculations for China with data from global IO models.
