Should countries be responsible for "exported" emissions?

33% of China's carbon footprint blamed on exports

Economists now say that one-third of China's carbon dioxide emissions are pumped into the atmosphere in order to manufacture exported goods – many of them "advanced" electronics goods destined for developed countries. "Export goods emissions" account for 1.7 billion tonnes of China's carbon dioxide. That represents 6% of total global emissions – the equivalent of Germany, France and the UK's combined emissions. A large share of these emissions – up to 25% – has been blamed on China's ever-growing export market, but this has not been quantified until now. Now Christopher Weber of Carnegie Mellon University in Pittsburgh, Pennsylvania, and colleagues have shown that the figure is larger still. Weber's team used a standard model of the Chinese economy, produced by the Chinese government. This model, which operates on the same principle as others produced by every national government, reflects how money has flowed in and out of different sectors of the economy since the 1980s. Matching the model to the dataset allowed the team to calculate that, in 2005, export sectors generated 1.7 billion tonnes of carbon dioxide – 33% of China's emissions.

An interesting study, and the focus of this week's poll. This issue was looked into at the Global Young Greens conference I attended earlier this year.

With huge amounts of products primarily consumed in developed nations now being manufactured in developing nations, this of course equates to an "exporting" of environmental impacts from the developed nations on to the developing nations. Should, in future global agreements on cutting carbon emissions, nations be responsible for emissions created from products they import, and not for products they export? Would this make things too complicated, in a field where it is already impossible to calculate exact carbon emissions? And, of course, the manufacturing nations benefit (to arguable extents) from the manufacturing being based in their countries. Should this be taken into account?

A very complex issue, but give your brains a bit of a stretch and vote in the poll to the right now.
