Editor’s note: Published in 2024, the Environmental Performance Index still offers a clear view of where environmental policy is working and where it is not. For GSN, this is exactly the kind of evidence-led reporting worth revisiting, to help readers understand the forces shaping climate, health and nature outcomes, and why progress varies across countries.
The EPI ranks 180 countries using 58 indicators across 11 issue categories, covering climate change performance, environmental health and ecosystem vitality. It is designed not just as a league table but as a practical tool for comparing peers, tracking trends and sharpening policy choices.
The EPI is designed as a national-scale gauge of how close countries are to meeting established environmental policy targets. It combines 58 indicators across 11 issue categories under three overarching policy objectives, weighted within a single framework. The report frames the index as a tool to identify problems, set targets, track trends and highlight effective policy practice, stressing that the most useful insights often emerge when readers look beyond the headline score and into the underlying data.
The policymakers’ summary argues that this kind of empirical approach has become more important as environmental risks compound. It points to continued reliance on fossil fuels as a driver of air and water pollution, ocean acidification and rising greenhouse gas concentrations, alongside habitat loss that is pushing some species closer to extinction. It also cites analyses suggesting humanity has already crossed six of nine “planetary boundaries”, and is close to crossing a seventh.
Climate rankings tighten as net-zero pace remains rare
The report’s climate section is framed around a central warning: the world is not on track to meet the goals of the 2015 Paris agreement, even as renewable energy deployment reaches record levels. Against that backdrop, the EPI introduces refined metrics intended to better track countries’ progress in curbing greenhouse gas emissions. These include measures that score emissions reduction or growth rates while considering proximity to a net-zero target, as well as pilot indicators that assess mitigation efforts against countries’ allocated shares of the remaining global carbon budget, reflecting the principle of common but differentiated responsibilities.
Using its analysis of emissions trends over the last decade, the report identifies only five countries as cutting greenhouse gas emissions at the rate needed to reach zero by 2050: Estonia, Finland, Greece, Timor-Leste and the United Kingdom. It adds that it is unclear whether these nations can sustain the pace achieved in recent years.
The ranking table in the summary places Estonia first overall with a score of 75.7, followed by Luxembourg (75.1) and Germany (74.5). The United Kingdom is ranked fifth with a score of 72.6. The United States is listed 35th with 57.2, while China is 156th with 35.4, India 176th with 27.6 and Russia 83rd with 46.7.
In current policy terms, Estonia’s high placing sits alongside a push to accelerate the shift away from its historic reliance on oil shale, with national and EU-facing plans aiming to cover annual electricity demand with renewables by 2030 as part of a broader climate-neutrality pathway. Russia, by contrast, has paired climate targets and reporting measures with an energy strategy that envisages expanded fossil fuel production and exports, and a 2035 emissions target that analysts say Russia is already on track to meet under existing policies. The result is a widening divergence in the direction of travel, even as both countries frame parts of their approach around future targets and longer-term transitions.
Biodiversity protection expands, but effectiveness is questioned
After climate change, the report describes biodiversity loss as the most serious and irreversible environmental crisis, warning that scientists believe a sixth mass extinction may already be under way. In response, the EPI adds new metrics to assess how well countries protect their most important habitats, and introduces pilot indicators that aim to measure the effectiveness and stringency of protected areas.
These additions are linked to the Kunming-Montreal Global Biodiversity Fraguarding 30% of land and seas by 2030. The pilot indicators suggest a critical tension: while many countries have met area-based protection goals, many protected areas have not halted the loss of natural ecosystems. The report argues that protected areas need adequate funding and stricter regulations developed in partnership with local communities.
Wealth, trade-offs and the limits of a single “best” model
A chart in EPI scores with GDP per capita and concludes that wealth is a strong predictor of overall environmental performance, although the relationship delivers diminishing returns beyond a point. At every income level, however, the report says some countries outperform their economic peers while others lag, and it notes that some of the poorest countries can outperform some of the richest. It points to factors beyond wealth, including investments in human development, the rule of law and regulatory quality, as stronger predictors of environmental performance.
The same breadth that makes the index comprehensive also exposes uncomfortreport argues that no country can claim to be on a fully sustainable trajectory, because gains in areas such as clean drinking water, waste management and renewable energy expansion can sit alongside higher material consumption and its impacts, including increased waste generation, emissions and ecosystem degradation. It also notes that some high scores in certain ecosystem vitality measures can reflect stagnant or underdeveloped economies, rather than deliberate success.
The policymakers’ summary links these trade-offs to the need for internatishifts in what societies value in development pathways. It warns developing countries against repeating “dirty and unsustainable” industrialisation routes, while arguing that richer countries need to decouple consumption from environmental degradation and use their wealth to help others leapfrog to more sustainable models.
Data gaps persist despite advances in technology
The report is presented by an unprecedented availability of environmental data, including developments in machine learning and remote sensing, which it says enable innovations in the index. Yet it also stresses that significant data gaps remain, creating challenges for robust policymaking.
It highlights longstanding shortages of high-quality, standardised data onaste and wastewater management, particularly in developing countries, arguing that these gaps make it harder to tackle plastic pollution and advance towards a circular economy. It also points to limited global data on the protection of wetlands, grasslands and other ecosystems that remain difficult to characterise through remote sensing.
Practical implications for policy and public scrutiny
For policymakerse is that the index is most useful when treated as a diagnostic tool rather than a scoreboard, with its disaggregated indicators helping to identify where interventions are working, where they are not, and how comparable countries are approaching similar constraints. For industry, investors and civil society, the rankings and category-level results can sharpen scrutiny of national claims, particularly where overall performance diverges from economic peers.
The EPI also encourages users to examine the underlying data and methodolot says are available through its website, positioning transparency and comparability as central to how the results should be used and debated, including in work aligned with the sustainable development goals.
