Because of this disparity, many groups are calling for a change to the Kyoto agreement practice of only counting CO2 emissions that are produced in-country, rather than the CO2 footprint of those products that are consumed. http://phys.org/news223031971.html Space & Earth Tue, 26 Apr 2011 10:19:49 EST news223031971 (AP) -- Nineteen years after the world started to take climate change seriously, delegates from around the globe spent five days talking about what they will talk about at a year-end conference in South Africa.
