India ranks second-lowest in the 2026 Environmental Performance Index, scoring just 22.46 out of 100 amid persistent air pollution, biodiversity loss and coal dependence, prompting renewed debate over methodology and policy urgency.

India has once again found itself near the bottom of a major global environmental ranking. In the 2026 Environmental Performance Index (EPI), released by researchers from Yale University and Columbia University, India ranked 176th out of 177 countries with a score of 22.46 out of 100. Only Laos scored lower. Estonia topped the list with 74.79.

The biennial index assesses countries on environmental health, ecosystem vitality and climate change mitigation. For 2026 it used 47 indicators across 12 issue categories. Environmental health carried 25 per cent weight, ecosystem vitality 45 per cent, and climate change mitigation 30 per cent. India ranked 174th in environmental health, 171st in ecosystem vitality and 130th in climate change. It also placed last among the eight South Asian countries assessed.

This continues a pattern of weak performance. India ranked last (180th) in 2022 with a score of 18.9, improved marginally to 176th out of 180 in 2024 with 27.6, and now sits second from the bottom again in 2026 among a slightly smaller set of countries. Ten-year trends show some gains in climate-related metrics, but overall scores remain low.

Persistent Challenges in Air Quality and Health

Air quality remains one of India’s weakest areas. The country ranks near the bottom on fine particulate matter (PM2.5) exposure, ozone and other pollutants that affect human health. Despite the National Clean Air Programme and substantial spending – reports cite more than ₹16,000 crore – scores on air quality have shown little or no improvement and in some measures have slipped slightly over the past decade.

Household solid fuels, industrial emissions and vehicle pollution continue to drive high exposure levels in cities and many rural areas. Related indicators for sanitation, drinking water and heavy-metal exposure also rank poorly, reflecting pressures from rapid urbanisation, population density and uneven infrastructure. Environmental health overall sits near the global floor, underscoring the human cost of pollution.

Ecosystem Vitality Under Pressure

Biodiversity and habitat protection form another major weakness. India scores low on species protection, terrestrial biome protection and key biodiversity area coverage. Tree-cover loss in important biodiversity areas has been flagged negatively. Protected-area effectiveness shows mixed results, but overall ecosystem vitality ranks among the lowest globally.

Fisheries indicators and some forest metrics also lag. While India has reported gains in certain forest-related measures in domestic assessments, the EPI’s satellite- and data-driven approach highlights ongoing habitat fragmentation, species threats and limited representativeness of protected areas. Data restrictions on some protected-area submissions have been noted by the EPI team in earlier editions as limiting full assessment for countries including India.

Climate Metrics Show Relative Bright Spots

Climate change is India’s relatively stronger category, ranking 130th. Gains stem from renewable energy expansion, declining growth rates in some emissions, and the long-term net-zero target of 2070. Adjusted emissions growth rates for certain gases have improved compared with past decades.

Yet projected emissions trajectories and continued heavy reliance on coal keep overall climate scores modest. India is the third-largest absolute greenhouse-gas emitter, though per-capita emissions remain relatively low. The tension between development needs – expanding energy access for hundreds of millions – and rising pollution and emissions is explicitly noted in EPI commentary.

Global Context and Regional Standing

European countries dominate the top ranks. Estonia’s lead reflects sharp reductions in greenhouse-gas emissions through cleaner energy transitions. Luxembourg, the United Kingdom, Finland, the Netherlands and other high-income European nations follow, benefiting from strong governance, advanced regulation and earlier industrial transitions.

Southern Asia and parts of Sub-Saharan Africa cluster toward the bottom. Within South Asia, India ranks last among the eight countries assessed. Neighbouring countries with lower per-capita incomes often score higher on the index, a point raised by analysts examining equity and development-stage differences.

Government Response and Methodological Debate

The Indian government has previously rejected EPI findings, most forcefully after the 2022 ranking that placed India last. The Ministry of Environment, Forest and Climate Change described indicators as based on “surmises and unscientific methods,” criticised projected-emissions calculations, data sources and weighting, and argued that the index fails to account adequately for historical low emissions, equity principles under the UN climate regime, or India’s renewable-energy progress.

Officials have pointed to domestic efforts on clean air, forests, sanitation and climate commitments. For the 2026 edition, responses have been limited, with some references back to earlier critiques. EPI researchers have defended the methodology as outcome-focused rather than policy-intention-focused, emphasising current environmental conditions measured by available data, including satellite observations. They have invited collaboration and argued that rejecting the findings forgoes a useful diagnostic tool.

Independent analysts note that wealth, governance quality and human-development levels correlate with higher EPI scores, creating structural challenges for developing economies. Critics of the index also question certain weightings and data gaps, while supporters treat the consistent low ranking as a signal that air quality, biodiversity protection and pollution controls require accelerated action.

Path Forward Amid Development Pressures

India faces the classic development-environment trade-off. Expanding energy access, industrialisation and urban growth have lifted millions out of poverty but intensified local pollution and emissions. Progress on renewable capacity, electric mobility, waste management and some sanitation indicators offer foundations. Scaling these while enforcing air-quality standards, strengthening protected-area networks, improving wastewater treatment and accelerating the coal-to-clean transition will determine future trajectories.
