This year’s Environmental Performance Index underscores the progress and setbacks in achieving environmental policy targets, offering valuable insights for policymakers and environmental stakeholders.
The 2024 Environmental Performance Index (EPI) offers a comprehensive sustainability assessment across 180 countries based on 58 performance indicators across 11 issue categories.
Published by Yale University’s Center for Environmental Law & Policy and Columbia University’s Center for International Earth Science Information Network, the EPI ranks countries on climate change performance, environmental health, and ecosystem vitality.
The index serves as a critical tool for policymakers, environmentalists, and researchers by highlighting leaders and laggards in environmental performance and providing practical guidance for achieving sustainable development goals. This year’s EPI, supported by the McCall MacBain Foundation, reveals significant insights into global progress and challenges in sustainability.
Key findings from the 2024 EPI
The 2024 EPI showcases some surprising developments and persistent challenges in global environmental performance. Estonia leads the rankings, largely due to its significant reduction in greenhouse gas (GHG) emissions. The country has managed a 40 per cent drop in GHG emissions over the last decade, primarily by replacing oil shale power plants with cleaner energy sources. Estonia’s efforts are complemented by its ambitious goal to achieve a CO2-neutral energy sector and public transport network by 2040.
Luxembourg and Germany follow closely, ranking second and third respectively. Luxembourg excels in ecosystem vitality, particularly with over 55 per cent of its land under protection. Germany’s high rank is attributed to its rapid deployment of renewable energy and comprehensive waste management practices.
However, the report highlights troubling trends in biodiversity conservation. Despite global commitments to protect 30 per cent of terrestrial, inland water, and marine areas by 2030, many protected areas are failing to curb destructive activities. The EPI reveals that in 23 countries, over 10 per cent of protected land is covered by croplands and buildings, while 35 countries report more fishing activity inside marine protected areas than outside.
Climate change mitigation and challenges
The EPI’s new metrics for climate change mitigation reveal that while GHG emissions are falling in more countries than before, the pace is still insufficient to meet global targets. Only five countries—Estonia, Finland, Greece, Timor-Leste, and the United Kingdom—have cut their GHG emissions at the rate needed to reach net zero by 2050. Estonia’s significant progress stands out, driven by a shift from oil shale to renewable energy sources.
Conversely, major economies such as the United States, China, Russia, and India continue to see slow reductions or even increases in GHG emissions. The report underscores that early gains from transitioning from coal to natural gas and expanding renewable energy are insufficient. Sustained investments in renewable energy, food system transformation, and urban redesign are necessary for meaningful progress.
Biodiversity and ecosystem vitality
Biodiversity loss remains a critical issue, with many nations struggling to protect vital ecosystems. The EPI introduces new metrics to assess the effectiveness of protected areas. These metrics reveal that while many countries have made strides in designating protected areas, the management and enforcement of these areas often fall short. In Europe, destructive fishing practices persist within marine protected areas, and in developing countries, inadequate funding and personnel hinder effective conservation efforts.
The EPI also highlights the importance of preserving high-value ecological areas. New indicators measure the protection of important habitats and the integrity of species’ habitats. This comprehensive approach aids in assessing progress towards global biodiversity targets and identifying areas needing urgent attention.
Environmental health and socioeconomic correlates
Environmental health scores vary widely, with wealthier countries generally performing better due to their ability to invest in pollution control and public health infrastructure. Iceland, for instance, scores highest in environmental health, showcasing effective pollution control measures. In contrast, low-income nations, particularly in Sub-Saharan Africa, struggle due to limited resources.
The report also explores the relationship between environmental performance and economic indicators such as GDP per capita and the Human Development Index (HDI). While wealth correlates strongly with environmental health, the relationship is weaker for ecosystem vitality and climate change. This highlights the complex interplay between economic development and environmental sustainability.
Regional and global rankings
European countries dominate the top ranks of the EPI, reflecting their comprehensive environmental policies and investments. Estonia’s rise to the top marks a significant achievement for Eastern Europe, driven by its robust climate policies and biodiversity conservation efforts. Luxembourg and Germany’s high ranks emphasize the importance of ecosystem protection and renewable energy deployment.
At the other end of the spectrum, Southern and Southeast Asian countries face significant challenges. Vietnam, Pakistan, Laos, Myanmar, and India rank lowest, struggling with high GHG emissions, severe air pollution, and ecosystem degradation. These countries’ reliance on coal and the environmental impacts of rapid economic growth underscores the need for international cooperation and support to enhance their sustainability efforts.
Conclusion and policy implications
The 2024 EPI provides a crucial tool for assessing global environmental performance and guiding policy decisions. The index’s comprehensive metrics highlight both achievements and areas needing urgent attention. Estonia’s success story demonstrates the potential of ambitious climate policies, while the challenges faced by developing nations underscore the importance of international cooperation.
Policymakers must leverage the EPI’s insights to refine their environmental strategies, focusing on sustainable energy transitions, effective biodiversity conservation, and robust pollution control measures. The EPI’s granular data and comparative perspective offer valuable guidance for setting targets, tracking progress, and identifying best practices.
Future directions
The EPI team continues to enhance the index’s methodology, incorporating the latest scientific data and refining indicators to provide a more accurate and comprehensive assessment. Future iterations will likely expand the scope of sustainability metrics, address persistent data gaps, and explore new dimensions of environmental performance.
The 2024 EPI serves as an indispensable resource for understanding global sustainability trends, celebrating environmental leaders, and motivating laggards to enhance their efforts. As the world grapples with the intertwined crises of climate change and biodiversity loss, the EPI’s insights are more vital than ever for shaping a sustainable future.
