Constraining World Trade Is Unlikely to Help the Climate, Study Finds
ScienceDaily, Sep. 23, 2012
From rubber dinghies to television sets: the emissions of greenhouse gases in countries like China are to a significant extent caused by the production of goods that are exported to Germany or the United States. But this doesn't necessarily mean that Western countries have relocated their emission-intensive industries and hence escape regulation for climate protection.

The need for new ocean conservation strategies in a high-carbon dioxide world
Greg H. Rau, Elizabeth L. McLeod & Ove Hoegh-Guldberg,Nature Climate Change, 19 August 2012
