Environmental Health

 Development that destroys nature is self-defeating. We measure how states manage pollution, conserve forests and water bodies, and adopt sustainable energy. Air and water pollution levels, compliance of industries, and disaster mitigation efforts are considered. Adoption of renewable energy and green transport infrastructure improves rankings.
Metrics include: AQI (air quality), stubble burning reports, waste processing rate, renewable energy share, change in forest cover, urban green space, and lake/river rejuvenation projects.
