List of countries by ratio of GDP to carbon dioxide emissions

From Wikipedia, the free encyclopedia

On 6 October 2009, the International Energy Agency (IEA) released for free download the 2007 numbers for over 140 countries/regions/economies at http://www.iea.org/co2highlights.

This is a list of countries arranged by their ratio of Gross domestic product (GDP, nominal and by purchasing power parities) to carbon dioxide emissions. GDP data is for the year 2006 produced by the International Monetary Fund. Carbon dioxide emissions data is for 2006, provided by the CDIAC for United Nations (see List of countries by carbon dioxide emissions).

Note that countries near the top of the list are the most efficient. They produce the most economic output with the least emissions. Countries at the bottom of the list are the worst polluters per unit of economic output.
