Answer: Uttarakhand
Notes: Uttarakhand is the first Indian state to launch a Gross Environment Product Index (GEPI). GEPI evaluates ecological development influenced by human actions. It focuses on four pillars: air, soil, trees, and water. The formula is: GEP index = (Air-GEP index + Water-GEP index + Soil-GEP index + Forest-GEP index). GEPI helps assess the impact of human activities on ecosystems, measures contributions back to the environment, and quantifies the economic and welfare benefits of natural ecosystems.
