What is Environmental Performance Index?

Environmental Performance Index (EPI) is a global assessment that measures how effectively countries protect ecosystems, improve environmental health and mitigate climate change. The 2026 edition evaluates 177 countries using 47 indicators.

The indicators are grouped into three policy objectives: Ecosystem Vitality (45%), Climate Change Mitigation (30%) and Environmental Health (25%). The index aims to compare national environmental performance using a common framework.

Why is Environmental Performance Index in News?

The release of the Environmental Performance Index 2026 has revived discussions on environmental governance after India ranked 176th out of 177 countries.

The ranking has also renewed debate over the methodology adopted by the index and the extent to which it reflects the developmental realities of emerging economies.

Key Features

• Global leaders: Estonia ranked first with a score of 74.79, followed by Luxembourg and the United Kingdom, with European countries dominating the top positions.
• India’s overall rank: India ranked 176th with a score of 22.46, ahead of only Laos and last among South Asian countries.
• Sectoral performance: India ranked 130th in Climate Change Mitigation, 171st in Ecosystem Vitality and 174th in Environmental Health. Its Air Quality ranking stood at 175th globally.
• Major challenges: Urban particulate pollution, coal-dependent electricity generation, biodiversity loss, tree-cover decline and overfishing contributed to the low score.
• Positive trend: Despite its low ranking, India recorded a positive 10-year improvement score of +7.47, indicating gradual environmental progress.

India’s Concerns with the EPI Methodology

The Ministry of Environment, Forest and Climate Change (MoEFCC) rejected the EPI methodology in 2022 and continues to question several aspects of the assessment framework.

• Performance contradiction: India ranked 23rd in the Climate Change Performance Index (CCPI) 2026 and achieved 50% non-fossil installed electricity capacity in 2025, despite its near-bottom EPI position.
• Per-capita emissions: India argues that the index gives greater weight to absolute emissions while insufficiently recognising comparatively low per-capita emissions.
• Historical equity: The methodology does not adequately reflect the principle of Common but Differentiated Responsibilities and Respective Capabilities (CBDR-RC) or historical emissions of developed countries.
• Indicator validity: India has questioned the scientific validity and weighting of indicators relating to carbon sinks, forest quality and proxy-based environmental estimates.
• Developmental equity: Uniform global benchmarks may not sufficiently account for developing countries’ need to expand electricity access, sanitation and infrastructure for large populations.

Way Forward

Global environmental assessment frameworks should continue improving scientific transparency while incorporating equity principles, developmental needs and reliable data. Greater collaboration between international institutions and national governments can strengthen the credibility of future assessments.

For India, sustained investment in clean energy, biodiversity conservation, pollution control and ecosystem restoration will remain essential irrespective of international rankings. Official environmental policies are available through the Ministry of Environment, Forest and Climate Change.
