NATURE recently recognized the work presented in this web page, and more specifically the Carbon Footprint of Nations paper. In the category ‘Community choice – the most viewed papers in science’, the paper was reviewed under the title Where greenhouse gases start. At the same time, we got word that the Resource Panel Report Priority Products and Materials – which triggered the work presented here – has been downloaded over half a million times from the UNEP webservers since its launch in June. Not at all bad!
