The Centre for Science and Environment (CSE) along with Down To Earth magazine released the “State of India’s Environment 2026: In Figures” report ahead of World Environment Day. The annual publication uses official government data to evaluate national and state-level performance across environment, agriculture, public health, and human development. The findings indicate that expanding ecological degradation and delayed progress toward Sustainable Development Goals (SDGs) are creating visible public health and infrastructure challenges. The report reveals that India has breached seven out of nine critical planetary boundaries, including climate change, biosphere integrity, and freshwater depletion.
Climate and Extreme Weather Patterns
The data points to an expansion in the frequency and economic toll of climate anomalies across the Indian subcontinent.
Frequency of Anomalies
India experienced extreme weather events on 99% of the days in 2025, an increase from 88% of days in 2024 and 89% in 2023. These events led to 4,421 human casualties nationwide.
Agricultural and Regional Losses
Extreme weather events damaged 17.41 million hectares of cropped area in 2025. This marks a sharp escalation from 3.61 million hectares of crop damage in 2024 and 2.09 million hectares in 2023. Himachal Pradesh recorded the highest frequency with 267 extreme weather days, followed by Kerala with 173 days and Madhya Pradesh with 162 days.
Forest Divergence and Human-Wildlife Friction
Land use changes and structural imbalances within protected forest areas have impacted biodiversity and altered wildlife behavior.
Forestland Diversion
India diverted approximately 97,000 hectares of forestland for non-forest industrial and infrastructural use between the fiscal years 2020-21 and 2024-25. Forest diversion rates increased across 26 states during this five-year window.
Human-Tiger Encounters
The report highlights changing tiger behavior and a rise in conflict outside protected reserves. Between January and June 2025, tiger encounters resulted in 43 human deaths near reserve boundaries, matching the 44 deaths recorded during the corresponding period in 2024. This behavioral change stems from habitat saturation and prey base depletion. Nearly 40% of the country’s tiger territory overlaps with land inhabited by roughly 60 million people across 20 states. Furthermore, the aggressive spread of the invasive plant species Lantana camara, which occupies nearly 50% of forest and scrublands, has suppressed native grasses and reduced the wild herbivore prey base.
Water Stress and Sinking Deltas
Groundwater extraction patterns are destabilizing major hydrological basins and river systems.
Aquifer Depletion
Fifteen states and Union Territories are extracting groundwater at rates that outpace natural annual recharge. The highest levels of net over-exploitation occur in Punjab, Rajasthan, and Haryana.
Subsidence of Major Deltas
The report warns that excessive sub-surface water pumping is causing major river deltas across India to sink at alarming rates, increasing their vulnerability to sea-level rise and saltwater intrusion.
Air Pollution Monitoring Disparities
The infrastructure built to track ambient air pollution displays acute geographic concentration, creating gaps in environmental safety data.
Population Coverage Gap
Only 15% of India’s population, or approximately 200 million individuals, resides within a 10-kilometer radius of an operational continuous ambient air quality monitor. The remaining 85% of the population, over 1.2 billion people, lives outside any active real-time tracking zone.
Geographic Clustering
Monitoring infrastructure is overwhelmingly concentrated inside tier-one cities, metropolitan zones, and state capitals. This leaves entire industrial belts, small towns, and fast-growing peri-urban clusters completely unmonitored.
Global Mortality Share
India’s share of global air pollution-attributed deaths increased from 23.76% to 25.34% between 2014 and 2023. Total annual deaths tied specifically to ambient fine particulate matter (PM2.5) rose by 61% over the past decade.
State Performance Rankings Across Themes
The report evaluates states across four specific development categories using a weighted index.
| Theme Evaluated | Top Performing States / UTs | Lowest Performing States / UTs | Key Measured Metrics |
| Environment | Goa, Assam, Andhra Pradesh, Tripura, Odisha (UT Top: Chandigarh) | Rajasthan, Tamil Nadu, Bihar, Punjab, West Bengal (UT Bottom: Puducherry) | Forest and biodiversity, climate risks, waste management, water resources |
| Agriculture and Land | Punjab, Haryana, Sikkim, Tripura, Jharkhand | Mizoram, Nagaland, Odisha, Telangana, Goa | Agricultural economy, input costs, farmer welfare index, sustainable land use |
| Public Health | Goa, Himachal Pradesh, Manipur, Kerala, Sikkim (UT Top: Delhi) | Madhya Pradesh, Bihar, Uttar Pradesh, Assam, Chhattisgarh | Cost of medical care, environmental risk factors, health outcomes, medical infrastructure |
| Human Development & Public Infrastructure | Goa, Nagaland, Tripura, Himachal Pradesh, Tamil Nadu (UT Top: Dadra & Nagar Haveli and Daman & Diu) | Jharkhand, Bihar, Uttar Pradesh, Odisha, Arunachal Pradesh (UT Bottom: Lakshadweep) | Roadways, power, housing, gender equity, education, unemployment, poverty ratios |
Summary of State Challenges
- The Population Burden: India’s five most populous states—Uttar Pradesh, Maharashtra, Bihar, Madhya Pradesh, and West Bengal—ranked poorly across the majority of the developmental and environmental indicators.
- Waste Management Crisis: Solid and hazardous waste management emerged as the single largest challenge across almost all states, with 15 states and Union Territories failing to clear the halfway mark in the environment index.
- Farmer Welfare Depressions: Twenty-seven states scored below the halfway mark under the Agriculture and Land theme, driven primarily by poor scores on farmer income stability and welfare metrics.
- Infrastructure Deficits: Under the Public Infrastructure and Human Development category, 32 out of 36 states and Union Territories fell below the halfway mark, highlighting gaps in housing, rural power delivery, and road connectivity.

The Planetary Boundaries Framework
The concept was developed in 2009 by the Stockholm Resilience Centre, led by Johan Rockström, to define nine safe operating thresholds for human survival. The nine boundaries are:
- Climate Change
- Biosphere Integrity (biodiversity loss and extinctions)
- Land System Change (such as deforestation)
- Freshwater Change (streamflow and soil moisture)
- Biogeochemical Flows (nitrogen and phosphorus cycles)
- Novel Entities (synthetic chemicals, plastics, heavy metals)
- Ocean Acidification
- Atmospheric Aerosol Loading
- Stratospheric Ozone Depletion
The State of India’s Environment 2026 report highlights that human activities have already breached seven of these nine systems, with ocean acidification newly entering the breached category as surface ocean acidity has increased by 30% to 40% since the pre-industrial era.
Centre for Science and Environment (CSE)
CSE is an independent, New Delhi-based public interest research and advocacy organization established in 1982 by environmentalist Anil Agarwal. It acts as a think tank analyzing air and water pollution, waste management, food safety, and climate change.
Regulatory Provisions for Environmental Governance
- The Environment (Protection) Act, 1986: Authorizes the central government to coordinate actions of state administrations, set national ambient standards, and close down polluting industrial units.
- The Forest (Conservation) Amendment Act, 2023: Regulates the de-reservation of forest lands and assignment of forest land by way of lease to private entities, establishing mandatory compensatory afforestation obligations.
- National Clean Air Programme (NCAP): Launched by the Ministry of Environment, Forest and Climate Change to achieve a 20% to 30% reduction in particulate matter concentrations across 131 non-attainment cities, using 2017 as the baseline year.
