Estonia ranked first in the latest biennial Environmental Performance Index released by Yale University, which assessed 177 countries. Luxembourg was ranked second, and the United Kingdom placed third in the index.

The UK moved up from fifth place in the 2024 index. The report noted progress in the UK concerning biodiversity protection on land and water, reductions in indoor and outdoor air pollution, and the decrease of greenhouse gases. The report also identified tree cover losses, bottom trawling, and fertilizer use as problem areas for the UK.

The United States placed 27th in the index. European countries occupied the top 20 positions, with Japan at 16th place. Australia ranked 25th. China ranked 129th, and India and Bangladesh were among the bottom three, with Laos listed as the last-ranked nation.

Daniel Esty, an environmental policy expert at Yale University, stated that there has been progress on some issues but not enough on critical areas such as climate change. "There's progress on some issues but not enough progress on a critical set of issues like climate change. And there's nothing like temperatures approach 40C in countries to help sharpen the focus on the need for a stepped up policy response," Esty said. He added that the index uses data up to 2024 and assesses 47 environmental indicators, including success in reducing air and water toxins, the sustainability of forests, fisheries, and farmlands, and actions to reduce pesticides and greenhouse gases.

"Air pollution has gotten a lot of attention in a number of countries and significant progress as a result, water availability, healthy drinking water is another issue that there's a quick public payback to in the political world," Esty said. "Europe has really stepped out in front and is continuing to pursue climate change with not the full vigor it might have a few years back when the political circumstances were different, but they're getting the payback for decades now of work on this issue at the cutting edge." He also commented on the performance of other nations. "The laggards in the US and China both are still lagging, seem to be falling further behind and are holding back the global community's efforts to achieve the targets that have been agreed upon," Esty said. China derives 56% of its electricity from coal, although it has removed many coal-fired power plants located near cities. The Yale index marked India down for tree cover loss, pesticide pollution risks, and ocean conservation compared to the previous index.

Estonia has recently worked to reduce greenhouse gas emissions and protect ecosystems. Leaders from Denmark, Turkey, Oman, and the Democratic Republic of the Congo have communicated with Yale researchers in recent years seeking guidance on improving their environmental performance scores. "With this kind of leaderboard very productive in spurring competitive efforts among leaders to do better, even the hardest of autocrats has called up for guidance," Esty said.

Why It Matters

The Environmental Performance Index, produced periodically by Yale University since 2002, provides a comprehensive assessment of environmental health and ecosystem vitality across nations. The index aims to encourage competitive efforts among countries to improve their environmental policies and outcomes. Its findings show global environmental challenges, indicating that while some progress has been made in areas like air pollution, issues such as climate change continue to require more substantial policy responses.

The rankings indicate that a wide range of countries, from top performers like Estonia to nations at the lower end such as Laos, are evaluated on environmental metrics. The engagement of leaders from various countries with Yale researchers demonstrates the index's role in influencing national environmental strategies. The current findings suggest that major economies like the U.S., China, and India are not advancing at the same rate as some European nations, potentially affecting overall global climate targets.
