 Over half of those emissions driven by demand from the West are from transnationals taking advantage of China's developmental policies favouring heavy manufacturing over regions with more developed environmental laws and enforcement.This includes many of the Walmart-suppliers and other foreign-owned factories that stock department store shelves, particularly in the US.China points out that it is being punished for having become "the place where the US effectively outsources much of its pollution," and has buttressed its call for joint international responsibility for at least part of China's emissions, by making public, in Jan 2008, Multinationals committed 130 violations of Chinese environmental law.
