Why count consumption rather than territorial CO2 emissions

In assessing progress on climate change, a crucial question is how to count greenhouse gas emissions, whether to assess territorial emissions or consumption emissions.

Territorial emissions are those within the borders of a country (or other area), i.e. ignoring emissions generated in the production of imported goods and including emissions generated in the production of exported goods.

Consumption emissions include emissions generated in the production of imported goods, and subtract emissions generated in the production of goods that are exported.

There are compelling arguments for using consumption rather than territorual emissions in assessing progress on reducing emissions .

Progress should be assessed on the basis of consumption emissions.

Terminology: territorial and consumption emissions

Territorial emissions are those within the borders of a country (or other area), i.e. ignoring emissions generated in the production of imported goods and including emissions generated in the production of exported goods.

Consumption emissions include emissions generated in the production of imported goods, and subtract emissions generated in the production of goods that are exported.

The chart shows how important the choice is. It shows the changes in UK greenhouse gas emissions since 1990. It is an edited version of a chart published by the UK Department for Business, Energy and Industrial Strategy [1]:

Considerations

The Rio Declaration of 1992 [2] is an international agreement that includes the principle that states should avoid the transfer of harmful activities to other states (Principle 14) - see document 113.

The emissions from the manufacture of, say, a washing machine are generally similar regardless of where it is manufactured. It does not make sense to say that a washing machine should be treated as zero-carbon simply because it was manufactured outside the country of residence.

A programme of "reducing emissions" by transferring manufacture of goods to another country would be non-sensical.

Groups and individuals advocating assessment via consumption emissions


Conclusion

In summary, there are compelling arguments for using consumption rather than territorual emissions in assessing progress on reducing emissions .

Progress should be assessed on the basis of consumption emissions.
