The New Economics Foundation, a think tank whose aim is "to improve quality of life by promoting innovative solutions that challenge mainstream thinking on economic, environment and social issues," has issued a Happy Planet Index which combines a country's environmental impact with human well being to show the relative efficiency with which nations convert the planet’s natural resources into long and happy lives for their citizens.
