Trade and Environment: Emissions intensity of Norway's imports and exports

Abstract

An Environmental Input-Output Analysis (EIOA) have been performed in order to assess the importance of including foreign emission and economic data when estimating emissions attached to imports. The CO2, SOx and NOx emissions induced by total imports are calculated using both foreign and domestic inventory. The results show significantly higher emissions when using foreign data, especially for SOx.

Demand-specific emission intensities are established for both import and domestic production. A comparison of those for emissions of CO2, SOx and NOx indicates much higher values for the imports than for the domestic production.

In addition, analyses are conducted on a more detailed level, defined by the NACE-industry aggregation. Foreign inventory are used on the imports, and domestic inventory are used on the domestic production. The detailed demand-specific emission intensities show similar trends compared with the total results mentioned above. However, there are considerable differences between some of the NACE sectors.

Finally, a brief overview of the assumed emissions related to household consumption is performed. However, the analysis are not on such a detailed level that conclusions can be made.
