Sikkim's deep reverence for nature is reflected in Gangtok's environmental policies and everyday civic life.
* **Organic State:** Gangtok is the capital of India's first 100% organic state. The use of chemical fertilizers and pesticides is banned by law. * **Cleanliness:** MG Marg (Mahatma Gandhi Marg), the city's pedestrian-only main street, is strictly a litter-free and spit-free zone. Fines are actively enforced. * **Air Quality:** The air quality is generally excellent (AQI typically between 20-50). However, during peak tourist seasons, narrow mountain roads experience traffic congestion, leading to localized vehicular emissions. * **Plastic Ban:** Sikkim was the first Indian state to ban disposable plastic bags (in 1998). Packaged drinking water bottles (under 2 liters) are heavily restricted, especially in government offices and certain tourist zones. * **Protected Areas:** The city is a gateway to the Khangchendzonga National Park, a UNESCO World Heritage site, which covers nearly 25% of the state's geographical area.
