According to 2016 Environmental Performance Index, which ranks 180 countries on how they protect human health and ecosystems, Estonia is the eighth most environmentally friendly country on planet Earth.

The annual Environmental Performance Index (EPI) is compiled by researchers from the US-based Yale University and Columbia University. The index ranks how well countries perform on high-priority environmental issues in two broad policy areas: protection of human health from environmental harm and protection of ecosystems.

The authors of the report said that the world is making progress addressing some environmental issues while others have worsened considerably.

There are promising trends in health impacts, access to drinking water, and access to sanitation. Air quality and fisheries, however, exhibit troubling declines. While the world’s nations protect more marine habitat than ever, the fish stocks are declining. The world also performs poorly on wastewater treatment and air quality.

EPI found that economic development leads to improvement in some environmental areas, yet development is also associated with increased prevalence of environmental hazards. “As nations have become wealthier, particularly in Asia, their governments invest in sanitation infrastructure and fewer people are exposed to unsafe water, leading to fewer deaths from waterborne illnesses. But as countries develop, increased industrial production, shipping, and automotive transportation foul the air, exposing human populations to dangerous airborne compounds. Thus, deaths attributed to air pollution have risen steadily in the past decade in step with exposure,” highlighting the fact that more than 3.5 billion people – half of the world’s population – live in countries with unsafe levels of air pollution.
