The Polluter is the Consumer

Here is another high level analysis of embodied carbon in imports by Oxford’s Dieter Helm (et al). It looks at the UK’s carbon emissions from the “consumption point of view.” The paper notes that using conventional producer-based carbon accounting-methods,
“UK greenhouse gas emissions have fallen by 15% since 1990. In contrast, on a consumption basis, the illustrative outcome is a rise in emissions of 19% over the same period. This is a dramatic reversal of fortune… It suggests that the decline in greenhouse gas emissions from the UK economy may have been to a considerable degree an illusion. Trade may have displaced the UK’s greenhouse gas appetite elsewhere.
The same paper has a well-articulated overview of the “consumer vs producer” paradigm:

“Both these [currently used] methodologies are based on the location of the production of greenhousegases. This, however, is a somewhat misleading and partial basis for policy purposes. For a country could have a very low production of greenhouse gases, but at the same time have a high consumption level. It could produce low-GHG-intensity goods, but import and consume high-GHG-intensity goods. Thus, a developed country might cease to produce steel, aluminium, glass and chemicals domestically, but import the manufactured goods from abroad. In the UK’s case, the shift of production in such activities to China, India and other developing countries in the last two decades suggests that this effect may be considerable… China might argue that, although it produces high emissions, these are on behalf of consumers in developed countries, and therefore the consumers should pay for the relevant reductions. In this way, the polluter is not the producer, but rather the consumer.
Also, the paper finds that “by 2006, the trade deficit in greenhouse gases [in the UK] was 341 MtCO2e, around 50% of domestic UK greenhouse gas emissions.” Another data point in understanding our total carbon footprint.
