The Happy Planet Index is an innovative new measure that shows the ecological efficiency with which human well-being is delivered around the world. It is the first ever index to combine environmental impact with well-being to measure the environmental efficiency with which country by country, people live long and happy lives. The results are surprising, even shocking, but there is much to learn from what they show.
