Using a new computational method, researchers at the Commerce Department agency found these have low global warming potential and boiling points low enough to be used in common refrigeration equipment.
Included in the plan is the 2010 Clean Air-Clean Jobs Act, which is intended to set emissions controls, retire inefficient coal power plants, and convert certain electric generating units from coal to natural gas.
The double-barrelled event in Austin, Texas, consists of a seminar on Sept. 10 and a workshop for oil & gas facilities' personnel on Sept. 11.
According to a study by the National Oceanic and Atmospheric Administration, the levels of certain vehicle-related pollutants in Los Angeles have dropped by 98 percent since the 1960s.
Roughly half the aerosols that affect air quality and climate change in North America may be coming from other continents.
Many marine species will be harmed or won't survive if the levels of carbon dioxide continue to increase.
The Department of Justice and the U.S. Environmental Protection Agency have announced a settlement with two subsidiaries of Sinclair Oil Corporation to resolve alleged violations of air pollution limits established in a 2008 consent decree at refineries in Casper and Sinclair, Wyo.
Even though it sounds like science fiction, researchers are taking a second look at a controversial idea that uses futuristic ships to shoot salt water high into the sky over the oceans, creating clouds that reflect sunlight and thus counter global warming.
Engineers at a company co-founded by a University of Texas at Dallas professor have identified a material that can reduce the pollution produced by vehicles that run on diesel fuel.
According to the United Nations' 2011 Revision of World Urbanization Prospects, global urban population is expected to gain more than 2.5 billion new inhabitants through 2050.
After studying a decade’s worth of satellite images, a team of researchers found what appears to be a correlation between El Niño events and increased deaths due to the pollutants in smoke from fires.
In California's Los Angeles Basin, levels of some vehicle-related air pollutants have decreased by about 98 percent since the 1960s, even as area residents now burn three times as much gasoline and diesel fuel.
Pine trees are one of the biggest contributors to air pollution. They give off gases that react with airborne chemicals -- many of which are produced by human activity -- creating tiny, invisible particles that muddy the air.
Even temporary rises in local temperatures significantly damage long-term economic growth in the world's developing nations, according to a new study co-authored by an MIT economist.
The design firm Perkins+Will has released what it calls the first-ever report on asthmagens and asthma triggers in building materials and products.
NOAA and the Interior Department's Bureau of Safety and Environmental Enforcement have expanded the online mapping tool used by emergency responders during the Deepwater Horizon oil spill response to include the Arctic, calling this step important for any response needed in the region.
The U.S. Environmental Protection Agency (EPA) awarded five grants totaling almost $2 million to academic institutions for research on innovative processes to further improve air quality in the U.S. and help track the effectiveness of pollution control measures.
The observations could have important implications for modelling global climate change and predicting air quality conditions. The tiny particles, which form part of an airborne chemical mix above cities, play a role in pollution by providing a surface for chemical reactions and in climate by reflecting and absorbing solar radiation and by acting as seed surfaces for water condensation and cloud formation.
Duane “Butch” O’Malley, 59, of Bourbonnais, Ill., who was convicted by a federal jury on September 26, 2011, for the illegal removal, handling and disposal of asbestos from a Kankakee building in August 2009, was sentenced to 10 years in prison by Federal District Court Judge Michael McCuskey.
The destruction of atmospheric ozone can take place within newly forming Polar Stratospheric Clouds (PSCs), which serve as the battleground for manmade chlorofluorocarbons (CFCs) to attack and destroy ozone.
