to read all about it. The EPI is basically a way to find relationships between countries' economies and their environments. Top-ranked countries means that they are the most productive and competitive in the world, while maintaining superb environmental standards. The top ranked enviro countries are New Zealand, Sweden, Filand, the Czech Republic and the United Kingdom. The 5 lowest are underdeveloped countries - Ethiopia, Mali, Mauritania, Chad and Niger. Canada is at number 8 and the United States is at number 28. China sits at 94...
The scores are based on health, biodiversity, energy, water, air and natural resources.
Health is based on child mortality, indoor air pollution, drinking water, adequate sanitation and ubran particles. Air quality is also based on urban particulates and regional Ozone. Water is based on nitrogen loading and water consumption. Water consumption is also a factor in biodviersty, along with wilderness protection and ecoregion protection. Natural resources she thefactor of timer harvest with biodiversity, but is also calculated by agricultural subsidies and over fishing. Finally, sustainable energy is based on energy efficiency, renewable energy and COs per GDP.
Why do we even need to have the EPI? It spots environmental problems - everywhere. It also helps determine where environmental policies are good enough, or insufficient. Its keeping check on governments and their environments. Not suprisingly there is a direct correlation between GDP per capita and where the country lands on the EPI and an even later correlation between their Human development index numbers, and their EPI.
Anywho, i read the full report, and then looked at the summary one - its just as good, actually. But the full report has a lot of cool graphs and maps to look at.
