Delhi NCR Activates Stage I GRAP as Air Quality Dips to ‘Poor’ – Implications for UPSC

Overview On 21 October 2026 the CAQM announced the launch of Stage I of the GRAP for Delhi and the National Capital Region. The move came after the city’s AQI entered the ‘poor’ band (201‑300). This development is a key case study for UPSC aspirants studying environmental governance and inter‑governmental coordination. Key Developments (Stage I) Immediate ban on the regular use of diesel generator sets in Delhi and neighbouring states. Strict enforcement of existing emission norms for industries and vehicles. State governments must issue orders to implement these measures; non‑compliance can attract legal action. Important Facts The GRAP framework has four stages: Stage I – ‘Poor’ (AQI 201‑300) Stage II – ‘Very Poor’ (AQI 301‑400) Stage III – ‘Severe’ (AQI 401‑450) Stage IV – ‘Severe +’ (AQI > 450) Higher stages trigger stricter actions such as bans on construction, demolition, and the entry of non‑BS‑VI vehicles. For example, under Stage III the CAQM prohibits plying of BS‑VI or lower diesel cars in Delhi and high‑density districts of Gurugram, Faridabad, Sonipat, Ghaziabad and Gautam Buddha Nagar. Stage IV further restricts truck entry, allowing only BS‑VI, electric, CNG or LNG trucks. The original authority for air‑quality management was the EPCA , created by the Supreme Court in 1998. Lacking statutory backing, EPCA was replaced by CAQM in 2021, which now enforces GRAP. A recent analysis by the CREA (released 22 October 2026) found no consistent improvement in Delhi’s winter AQI over the past four years despite GRAP’s implementation. Mean AQI rose from 280 (2022‑23) to 304 (2023‑24), fell to 285 (2024‑25) and rose again to 295 (2025‑26). The median showed a similar pattern. UPSC Relevance Understanding GRAP helps aspirants answer questions on: Environmental policy design and the role of statutory bodies (GS3). Centre‑State coordination in implementing emergency measures (GS2). Effectiveness of short‑term versus long‑term pollution control strategies (GS3). Legal frameworks empowering agencies like CAQM and the consequences of non‑compliance (GS2). Way Forward While Stage I focuses on enforcing existing norms, experts suggest that lasting improvement requires: Strengthening statutory powers of CAQM to ensure swift action. Integrating long‑term measures such as renewable energy adoption, stricter vehicular emission standards, and sustainable agricultural practices to curb stubble burning. Coordinated winter‑specific restrictions by the Delhi government (e.g., bans on non‑BS‑VI vehicles from 1 Nov 2026 to 31 Jan 2027) that operate irrespective of AQI, with GRAP taking precedence in case of conflict. These steps can help reduce Delhi’s recurring winter smog and provide a robust case study for governance and environmental management in the UPSC syllabus.
