Costa Rica is world's greenest, happiest country

Costa Rica is the greenest and happiest country in the world, according to a new list that ranks nations by combining measures of their ecological footprint with the happiness of their citizens.

Britain is only halfway up the Happy Planet Index (HPI), calculated by the New Economics Foundation (NEF), in 74th place of 143 nations surveyed. The United States features in the 114th slot in the table. The top 10 is dominated by countries from Latin America, while African countries bulk out the bottom of the table.

The HPI measures how much of the Earth's resources nations use and how long and happy a life their citizens enjoy as a result. First calculated in 2006, the second edition adds data on almost all the world's countries and now covers 99% of the world's population.



NEF says the HPI is a much better way of looking the success of countries than through standard measures of economic growth. The HPI shows, for example, that fast-growing economies such as the US, China and India were all greener and happier 20 years ago than they are today.

"The HPI suggests that the path we have been following is, without exception, unable to deliver all three goals: high life satisfaction, high life expectancy and 'one-planet living'," says Saamah Abdallah, NEF researcher and the report's lead author. "Instead we need a new development model that delivers good lives that don't cost the Earth for all."

Costa Ricans top the list because they report the highest life satisfaction in the world, they live slightly longer than Americans, yet have an ecological footprint that is less than a quarter the size. The country only narrowly fails to achieve the goal of what NEF calls "one-planet living": consuming its fair share of the Earth's natural resources.
