"Several parts of Delhi recorded an air quality index (AQI) of 400 and even 450 a level considered as severe under international pollution standards. Every winter, air pollution in Delhi spikes around this time when cold air traps smoke and fumes from fireworks, stubble burning and heavy traffic. The crisis is aggravated by vehicular and industrial emissions, massive road dust, construction activities and coal and biomass-fired residential heating."
"China's temporary emission reduction regulations for the 2008 Beijing Olympics set the stage for its war on air pollution. With the launch of a five-year national action plan in 2013, the country introduced a raft of measures, including the closure of coal-fired boilers, promoting public transport and new energy vehicles, accelerating technological reform of enterprises and boosting innovation and green energy."
New Delhi and surrounding areas experience hazardous winter air pollution, with AQI readings reaching 400–450 as cold air traps smoke and fumes from fireworks, stubble burning, and heavy traffic. Vehicular and industrial emissions, road dust, construction, and coal and biomass residential heating further aggravate pollution across dozens of Indian cities. Beijing achieved major air-quality improvements while maintaining economic growth through stringent measures, enforcement, and coordinated policy. China implemented temporary Olympic reductions, then a five-year national action plan in 2013 that closed coal-fired boilers, promoted public transport and new-energy vehicles, accelerated enterprise technological reform, and boosted innovation and green energy. The plan prioritized cutting PM2.5, which penetrates deep into lungs and the bloodstream and poses severe health risks.
