Significant recent attention has been given to quantifying
the environmental impacts of international trade. However,
the United States, despite being the world’s largest emitter
of greenhouse gases and having large recent growth in
international trade, has seen little analysis. This work uses
a multi-country input-output model of the U.S. and its
seven largest trading partners (Canada, China, Mexico,
Japan, Germany, the UK, and Korea) to analyze the
environmental effects of changes to U.S. trade structure
and volume from 1997 to 2004. It is shown that increased
import volume and shifting trade patterns ring this
time period led to a large increase in the U.S.’ embodied
emissions in trade (EET) for CO2, SO2, andNOx. Methodological
uncertainties, especially related to uncertainties of
international currency conversion, lead to large differences
in estimation of the total EET, but we estimate that the
overall embodied CO2 in U.S. imports has grown from between
0.5 and 0.8 Gt of CO2 in 1997 to between 0.8 and 1.8 Gt
of CO2 in 2004, representing between 9-14% and 13-30%
of U.S. (2-4% to 3-7% of global) CO2 emissions in 1997
and 2004, respectively.
