Sorry, I don't think so. The fine article already answers your question and I concur with the approach, originally posted by kitd, key phrase restated here:
Territorial emissions accounting might not be perfect, Mabey says, but in terms of simplicity it is the more practical approach. Lord Deben, chair of the UK’s Committee on Climate Change, told the BBC the UK only has direct control over its home-grown emissions, whereas manufacturing methods and energy choices in China are outside our control.
By consequent, I disagree with your more holistic approach of measuring carbon costs as it is based on a moral judgement, and not a quantity that we can measure in any reasonable way.
