# Pollution, waste & sustainable development

Pollution control regimes (air, water, plastic, e-waste), India's waste-management rules, and the sustainable-development framework for UPSC GS-3.

## The statutory backbone of pollution control

India's pollution-control regime rests on three pillars enacted under the constitutional mandate of Article 48A (Directive Principle: protect and improve the environment) and Article 51A(g) (Fundamental Duty). The **Water (Prevention and Control of Pollution) Act, 1974** created the Central Pollution Control Board (CPCB) and the State Pollution Control Boards (SPCBs), and introduced the discharge consent mechanism. The **Air (Prevention and Control of Pollution) Act, 1981** extended the same board structure to air quality and was passed to give effect to the 1972 Stockholm Conference decisions. The **Environment (Protection) Act, 1986**—an umbrella legislation enacted in the aftermath of the December 1984 Bhopal gas tragedy—empowers the Central Government to set standards, regulate hazardous substances and issue directions (Sections 3, 5 and 6). Almost every subordinate rule on waste is notified under the EPA, 1986.

## Air and water: standards and instruments

The CPCB notifies **National Ambient Air Quality Standards (NAAQS)**, last revised in 2009, covering 12 pollutants including PM2.5, PM10, SO2, NO2 and ozone. The **National Air Quality Index (AQI)**, launched in 2015 under the slogan 'One Number, One Colour, One Description', classifies air from Good (0–50) to Severe (401–500). The **National Clean Air Programme (NCAP)**, launched 2019, targets reduction of particulate pollution in 131 non-attainment cities, with a revised goal of up to 40% reduction in PM concentration by 2025–26 (against 2017 levels). For water, the **Namami Gange** programme (National Mission for Clean Ganga, 2014) and the **Jal Shakti Ministry** consolidate riverine pollution abatement. The **National Green Tribunal**, established under the NGT Act, 2010, adjudicates environmental disputes and applies the Polluter Pays and Precautionary principles affirmed in *Vellore Citizens Welfare Forum v. Union of India* (1996).

## Waste-management rules of 2016 and after

A suite of rules notified in 2016 under the EPA modernised waste governance: the **Solid Waste Management Rules, 2016** (segregation at source, user fees), **Plastic Waste Management Rules, 2016** (amended 2021–2022 to ban identified single-use plastics from 1 July 2022 and mandate Extended Producer Responsibility), **E-Waste (Management) Rules, 2016** (replaced by the 2022 Rules with an EPR-certificate regime effective 1 April 2023), **Bio-Medical Waste Management Rules, 2016**, **Construction and Demolition Waste Rules, 2016**, and **Hazardous and Other Wastes Rules, 2016**. The unifying instrument across plastic, e-waste and battery streams is **Extended Producer Responsibility (EPR)**—the principle that producers bear financial and operational responsibility for the post-consumer stage. The **Battery Waste Management Rules, 2022** apply EPR to all battery types. Candidates should connect these to the circular-economy push and to India's **Mission LiFE** (Lifestyle for Environment), launched at COP26 Glasgow (2021), which reframes consumption-side behaviour as a climate strategy.
