Environmental Performance Index

Environmental Performance Index

The 2022 Environmental Performance Index (EPI) provides a data-driven summary of the state of sustainability around the world. Using 40 performance indicators across 11 issue categories, the EPI ranks 180 countries on climate change performance, environmental health, and ecosystem vitality. These indicators provide a gauge at a national scale of how close countries are to established environmental policy targets.

Friday, July 15, 2022

The recently released 2022 EPI highlights the leaders and laggards in the fight against climate change. Denmark and the UK, taking the #1 and #2 spot in the ranking, have emerged as the only leaders on track for net-zero emissions by 2050. The U.S. has tumbled in the ranking, largely due to the climate inaction of the Trump Administration. For the first time, India has secured the last spot in environmental performance.

The 2014 Environmental Index (EPI) ranks countries on high-priority environmental concerns, including air quality, water management, and climate change. In this podcast, Angel Hsu, lead author of the 2014 EPI, discusses the rankings and global performance trends. Overall, the index reveals that the world is doing well on improving drinking water and sanitation. Progress in these categories tracks the concerted pursuit of the Millennium Development Goals, which have clear targets, strategies, and metrics for assessment on water and sanitation.

EPI Insights: Protected Areas

Biodiversity underpins all ecosystem services that sustain our environment and power our economies. Intact and sufficient habitat is critical to supporting ecosystems and maintaining biodiversity. However, natural habitats have witnessed considerable declines in biodiversity in recent decades, and today many species are at risk of extinction.
