An interesting paper on carbon emissions

Groundbreaking data tracks carbon emissions back to their source | Duncan Clark | Environment | guardian.co.uk: "Which of the following accounts for the largest share of the UK's carbon footprint? All our holiday flights, all the power used in our homes or … Russia?

Okay, so it's kind of a trick question, but according to a scientific paper published this week, we might reasonably conclude that the answer is Russia – though to understand why it's necessary to go back a couple of steps.

For the purposes of the Kyoto treaty, a nation's carbon footprint is considered to be a sum of all the greenhouse gas released within its borders. But as many people – myself included – have been pointing out for years, that approach ignores all the laptops, leggings, lampshades and other goods that rich countries import from China and elsewhere."
