The Central Valley’s heavy wintertime tule fog – known for snarling traffic and closing schools — has been on the decline over the past 30 years, and falling levels of air pollution are the cause, says a new study by scientists at the University of California, Berkeley.

Heavy-duty trucks, such as the 18-wheelers that transport many of the world’s goods from farm or factory to market, are virtually all powered by diesel engines.

What was once the largest coal-fired power plant in North America has been converted to a 44-megawatt solar farm with 192,431 photovoltaic panels spread across 260 acres, the electric utility Ontario Power Generation announced.

From astronauts and submariners to miners and rescue workers, people who operate in small enclosed spaces need good air quality to work safely and effectively. 

Green roofs – roofs that are planted with vegetation -- may improve the indoor air quality of commercial buildings by cutting the amount of ozone coming into the buildings from the outside, according to new research from Portland State University.

Improving the health of our ocean requires investment. But that investment doesn’t have to be a choice between our planet and our pocketbooks.

Discovering the little-known effects chemicals released in our lakes and rivers might have on the surrounding wildlife and ecosystems can give scientists and conservationists powerful insight into the development of better, more efficient environmental guidelines.

Plastic pollution in the world’s oceans is now widely recognised as a major global challenge – but we still know very little about how these plastics are actually reaching the sea.

The quest to keep plastic out of landfills and simultaneously satisfy the needs of the food industry is filled with obstacles.

A team of air quality and health researchers led by the Texas A&M Transportation Institute (TTI) has created a first-of-its-kind, county-by-county interactive heat map and city-by-city table detailing the distribution of childhood asthma due to traffic-related air pollution across the United States.
