From winter to summer, Delhi’s air has shown a slow but steady rise in carbon monoxide levels this year till May.

India's automobile sector saw 480 new entrants in FY26, up 37 per cent year-on-year, with electric vehicle makers dominating registrations across categories amid policy support.

A ‘moderate’ May AQI looks great on paper. But with unhealthy PM10 levels, toxic ozone spikes, hidden SO2, and monitoring stations hidden amongst vegetation, the capital’s clean air narrative is mostly hot air.

The increase in solar power generation has not been accompanied by the needed push to develop transmission and storage systems, experts say.

The cleaner PM2.5 levels also coincided with favourable weather conditions during the month.

India’s growing dependence on private vehicles and imported oil is making the country more vulnerable to global shocks.

Indian politicians have denied the severity of the air pollution crisis in the country for decades. Documents related to an update of the National Ambient Air Quality Standards (NAAQS) show how the denial has constrained policymakers.

Even though Mumbai’s overall air quality stayed satisfactory through May, Bandra Kurla Complex (BKC) recorded the city’s highest AQI at 162.

Delhi's PWD faces criticism for using diesel generators for monsoon prep amid fuel austerity measures, highlighting the need for cleaner, resilient infrastructure.

Delhi authorities have introduced a rule requiring green construction-site nets to be at least 100 GSM thick because thinner nets do not properly stop dust pollution.

The city has seen a sharp fall in fine particle pollution (PM2.5) over the past decade, dropping by more than half from 198.44 micrograms µg/m³ in 2015-16 to 91.7 in 2026-27, a decline of nearly 54% over the decade.

The article says a new study by researchers at Indian Institute of Technology Delhi found that India could prevent about 1.24 lakh early deaths every year if coal power plants properly controlled sulphur emissions.

The report says Gurgaon’s PM2.5 pollution levels dropped by nearly 54% between 2015 and 2026, falling from about 198 to 92 micrograms per cubic metre. Most of the improvement happened before 2020, but progress has slowed sharply since then.

Road RADAR, a new pollution monitoring program in Delhi, will deploy 13 surveyors to pinpoint dust pollution sources on the city's 18,000km road network.

A new study by IIT Delhi’s Centre for Atmospheric Sciences shows that limiting sulphur emissions across India could drastically improve air quality.

Ozone does not produce the haze associated with PM pollution. However, its public-health implications should not be downplayed.

A long-term study of air pollution data in Indian cities found that different pollutants rise and fall in different seasons. In Delhi, PM2.5 and PM10 levels are highest in winter, while ozone peaks in summer.

Over the years, January PM2.5 levels in Delhi have typically ranged well above safe limits, often crossing 150 micrograms per cubic metre, before dropping during monsoon.

For May, this was the lowest in three years, since May 31, 2023, when it was recorded at 85 (satisfactory), according to data from the Central Pollution Control Board
