An anonymous reader writes with a quick bite from Nature World News: "The contribution of economic decline in reducing greenhouse gas emissions is very low, reveals a new study. Researcher Richard York of the University of Oregon studied data collected between 1960 and 2008 from more than 150 nations in order to analyze the impact of economic decline on greenhouse gas emissions." From the paper: "In Model 2, the percentage of the population living in urban areas and the percentage of GDP from the manufacturing sector were included as control variables. This model has lower data coverage than Model 1 (154 versus 160 nations, and 4,134 versus 5,630 nation-year observations) owing to missing data on the control variables. The coefficients, at 0.752 for growth and 0.346 for decline, are similar to those from Model 1 and, as in Model 1, are both significantly different from 0 and significantly different from each other."
