‘Wake-up call’, say experts as India gets second lowest global ranking on Yale’s environment performance index; also raise questions on methodology
India ranked 176th out of 177 countries in Yale University's 2026 Environmental Performance Index (EPI), the second-lowest ranking in the index, ahead only of Laos
Experts described the ranking as a "wake-up call," while also raising questions about the index's methodology
India's EPI score was 22.46 out of 100, compared to topper Estonia's score of 74.79
India performed particularly poorly on air quality and biodiversity indicators, but showed relative improvement on the climate change mitigation category
The findings renew a recurring debate: whether the index captures genuine environmental problems or is methodologically biased against large, populous, developing economies
The Environmental Performance Index (EPI): Structure and Methodology
The EPI is a biennial ranking produced by Yale University (with Columbia University) that scores and ranks countries on environmental health and ecosystem vitality. It aggregates dozens of indicators across issue categories into a single composite score, intended to allow cross-country comparison of environmental performance.
Key Details
- The 2026 edition assessed 177 countries across 47 indicators grouped into 12 issue categories
- Three broad policy objectives are weighted: Environmental Health (25%), Ecosystem Vitality (45%), and Climate Change Mitigation (30%)
- India's sub-rankings: air quality 174th, biodiversity 174th (weakest areas); climate change mitigation 130th (improved roughly 14 points over the decade); waste management and sanitation 141st
- India's historical EPI trajectory: 141st (2016) → 177th (2018) → 168th (2020) → 180th, worst globally (2022) → 176th (2026)
The near-bottom ranking, despite India's improvement in the climate mitigation sub-category, illustrates how a composite index can obscure sector-specific progress (climate policy) while flagging genuine, severe deficits (air quality, biodiversity).
Methodological Criticism of Cross-Country Environmental Indices
A recurring critique — raised by the Government of India as well as independent research bodies such as TERI (The Energy and Resources Institute) — is that composite indices like the EPI compress diverse, large, low-income countries into a single comparative score using indicator weights that may reflect global-north policy priorities rather than a developing country's context (e.g., poverty alleviation, energy access) or its historical (per-capita cumulative) emissions responsibility.
Key Details
- The Union Ministry of Environment, Forest and Climate Change had previously rejected the 2022 EPI ranking (India ranked last, 180th) as being based on "surmises and unscientific methods"
- Yale's EPI methodology has changed across editions, making longitudinal year-on-year comparisons difficult
- The EPI evaluates current-state performance rather than a country's stated future commitments (e.g., Nationally Determined Contributions) or historical/cumulative emissions
- TERI has argued that indicator selection and weighting in such indices can be arbitrary and skewed toward criteria that disadvantage large developing economies
The "wake-up call" framing versus "methodology questions" framing in the coverage reflects this same long-running tension — Indian experts cited in the report acknowledge the EPI captures real problems (air pollution, biodiversity loss, fossil fuel dependence) even while flagging its comparative-scoring limitations.
Air Quality and Biodiversity as India's Weakest Environmental Indicators
Air quality (linked to particulate matter concentrations and health outcomes) and biodiversity (linked to habitat loss, protected area coverage and species trends) are the two categories where India scores worst on the EPI, consistent with domestic data showing high ambient particulate pollution in northern Indian cities and continuing habitat fragmentation pressures.
Key Details
- India's air quality sub-rank: 174th of 177 in the 2026 EPI
- India's biodiversity sub-rank: 174th of 177 in the 2026 EPI
- Domestic frameworks relevant to these categories: National Clean Air Programme (NCAP, launched 2019) for air quality; Wildlife Protection Act, 1972 and India's National Biodiversity Action Plan for biodiversity conservation
- India is a signatory to the Kunming-Montreal Global Biodiversity Framework (2022), which sets a "30x30" target — protecting 30% of land and sea area by 2030
The EPI's weakest sub-scores for India align with the two areas — air pollution and biodiversity loss — most frequently flagged in domestic environmental policy discussions, lending credibility to the index's substantive findings even amid methodological critique.
- India's 2026 EPI rank: 176th of 177 countries; score 22.46/100
- Only country ranked lower: Laos
- Topper: Estonia, score 74.79/100
- India's weakest sub-categories: air quality (174th), biodiversity (174th)
- India's best-performing sub-category: climate change mitigation (130th; improved ~14 points over the past decade)
- EPI 2026 covers 177 countries, 47 indicators, 12 issue categories
- Category weights: Environmental Health 25%, Ecosystem Vitality 45%, Climate Change Mitigation 30%
- India's EPI rank history: 141st (2016), 177th (2018), 168th (2020), 180th (2022, worst globally), 176th (2026)
