Grap-3 restrictions reimposed in Delhi-NCR as AQI dips to 'severe' category

The central government on Sunday ordered a ban on non-essential construction work and plying of BS-III petrol and BS-IV diesel four-wheelers in Delhi-NCR amid worsening air quality in the region. The Commission for Air Quality Management, a statutory body responsible for forming air pollution reduction strategies for the region and their implementation, noted a significant rise in Delhi's AQI (458 and 457 at 10 am and 11 am) due to unfavourable climatic conditions and local pollution sources. Anticipating a prolonged period of severe air quality, the committee decided to implement GRAP Stage-III curbs ('severe' air quality index (AQI) range) immediately to prevent further deterioration. The curbs include a ban on non-essential construction work and the plying of BS III petrol and BS IV deisel four-wheelers in the region. Construction work related to national security or defence, projects of national importance, healthcare, railways, metro rail, airports, inter-state bus terminals,

Improvement in Delhi's PM2.5 levels since 2015-17 halted in 2023: CSE

Delhi-NCR recorded the longest spell of 'very poor' or worse air quality and the maximum number of smog episodes in November and December 2023 in the last six years, according to a new analysis. The Centre for Science and Environment (CSE), an independent think-tank that analysed pollution data for Delhi-NCR, said the gradual long-term improvement in annual PM2.5 levels since 2015-17 halted in 2023. This occurred despite cleaner-than-usual summer and monsoon seasons and significantly reduced intrusion of smoke from farm fires in northern states. However, this winter witnessed unusually low surface wind speeds, trapping high levels of local pollution. Due to the impact of unusual winter levels, the overall annual levels have plateaued and worsened, reversing the gains of the long-term downward trend, the CSE said. Despite a decrease in stubble burning contributing to Delhi's pollution this year, coupled with increased rainfall in November and milder winter conditions, the annual lev
