Delhi has notified a permanent winter anti-pollution framework that automatically applies every year from November 1 through February 28, consolidating earlier seasonal orders into a single set of measures. The plan is issued under the Environment (Protection) Act, 1986 and is described as a baseline set of rules, while the Graded Response Action Plan (GRAP) can override the directions when activated. Vehicle-related steps include mandatory Pollution Under Control (PUC) compliance, with petrol pumps required to supply fuel only to vehicles with valid PUC certificates, monitored through electronic verification and ANPR, alongside penalties for violations. From November 1 to January 31, non-Delhi registered vehicles that do not meet BS-VI emission norms are barred from entering the national capital, with exemptions for CNG, electric and emergency vehicles. To reduce traffic, parking charges at authorised facilities are doubled and government and private offices run with staggered hours and a 50% work-from-home norm. Construction and demolition activities that generate dust are restricted during the period, with broader suspensions between December 10 and January 20 and bans on entry for vehicles transporting construction material. The framework also requires anti-smog systems on larger buildings and dust-control systems at larger construction sites, and calls for strict action against open waste burning by residents’ bodies and institutions.
