Hill states need a different demand-aggregation model for procurement of electric buses to meet their unique requirements When there is so much focus on expanding electric bus (e-bus) services in the cities located in the plains, there is little understanding of what it takes to establish and sustain e-bus programmes in the hill states of … Read more
The new state budget of Delhi promises upscaling of public transport and bus fleet electrification. But the new Economic Survey warns about plummeting bus ridership The new budget proposal tabled by the Government of National Capital Territory of Delhi makes promises of upscaling the bus transport system and augmenting electric bus fleet. This has set … Read more
State environmental officials waited nearly two years to alert the public that cancer-causing vapors over 20 times the amount considered safe escaped from polluted soil along the Gowanus Canal — and into a nearby shuffleboard club. The Department of Environmental Conservation learned of the alarming levels of toxic vapors in March 2021 while conducting air-quality … Read more
Commuters make their way along a street amid smoggy and foggy conditions early in the morning in Lahore on January 3, 2023. Arif Ali | AFP | Getty Images About 90% of the global population in 2022 experienced unhealthy air quality, and only six countries met the World Health Organization’s recommendations of safe air pollutant … Read more
San Francisco regulators moved forward with regulations banning future sales of certain natural gas-powered appliances as part of the Democrat-led city’s climate agenda. The Bay Area Air Quality Management District, which oversees air pollution and emissions regulations for the nine counties surrounding San Francisco, greenlighted amendments to regulations Wednesday evening related to eliminating nitrogen oxide emissions from … Read more
There is currently a large dependence on coal for power generation. As coal-fired plants cause environmental and health hazards, technologies such as swirl flow and air staging have been proposed to mitigate the pollutants in their emissions. However, it is unclear how effective these technologies are in reducing the environmental costs of these plants. Now, … Read more
Many developing countries, unlike India, do not have proper air monitoring systems; if they did, India’s ranking would be better Delhi’s iconic Red Fort enveloped in smog.

Electrification is seen as having an important role to play in the fossil-free aviation of tomorrow. But electric aviation is battling a trade-off dilemma: the more energy-efficient an electric aircraft is, the noisier it gets. Now, researchers have developed a propeller design optimization method that paves the way for quiet, efficient electric aviation. Source link
A research team demonstrates that increased levels of ozone resulting from anthropogenic air pollution can degrade insect sex pheromones, which are crucial mating signals, and thus prevent successful reproduction. The oxidizing effect of ozone causes the carbon-carbon double bonds found in the molecules of many insect pheromones to break down. Therefore, the specific chemical mating … Read more
Globally, wildfires are becoming more frequent and destructive, generating a significant amount of smoke that can be transported thousands of miles, driving the need for more accurate air pollution forecasts. Researchers have now developed a deep learning model that provides improved predictions of air quality in wildfire-prone areas and can differentiate between wildfires and non-wildfires. … Read more
