Highway Barriers Stifle Pollution
January 6, 2010 01:48 PM - Andy Soos, ENN

Highway barriers erected along roadways can be perceived as massive monuments to the future and were intended to block the sound and sight of traffic for the adjacent neighborhoods. They may do a bit more in terms of air borne pollution. In a study by NOAA and the US Environmental Protection Agency, researchers released harmless “tracers” to measure the potential movement of pollutants such as carbon monoxide and heavy metals, and volatile organic compounds such as benzene. The results showed a significant reduction for those neighborhoods in pollutants as a result of the barriers.

US Car Fleet Shrinks for First Time
January 6, 2010 06:42 AM - Timothy Gardner, Reuters

Americans scrapped more automobiles than they bought last year as the ragged economy reduced demand and some major cities expanded mass transit service, according to a new report. The United States scrapped 14 million autos while buying only 10 million last year, shrinking the country's car and light duty truck fleet to 246 million from a record high of 250 million, according to the report to be released on Wednesday by nonprofit group the Earth Policy Institute (EPI). The United States, the world's biggest petroleum user, "is entering a new era, evolving from a car-dominated transport system to one that is much more diversified," said Lester Brown, the president of the EPI.

The Origin of Green Chemistry

Where does "Green Chemistry" come from? What is it? J.A. Linthorst, who is affiliated with Descartes Center (Utrecht University) and Maastrict University, has studied the matter and the history of the term in an article entitled: "An Overview: Origins and Development of Green Chemistry". He has found where the term begins and how it has evolved.

Carbon Dioxide Recovery and Use

The Middle East's first carbon dioxide recovery plant has been opened at the Gulf Petrochemical Industries Company. This is also one of the first in the world to successfully recycle carbon dioxide air emissions. The $55 million facility at the company's Sitra facility was formally inaugurated by GPIC chairman and adviser to the Prime Minister for oil and industrial affairs Shaikh Isa bin Ali Al Khalifa, in the presence of board members, company officials and guests.

Colombia: Galeras volcano erupts again

The Galeras volcano in southern Colombia erupted on Saturday, shooting rock and ash and prompting authorities to order the evacuation of about 8,000 people. No one was killed or injured in the eruption. But officials warned that the volcano could remain volatile.

The Lawyers Win in Global Warming
December 28, 2009 09:31 AM - Andy Soos, ENN

Carbon dioxide air emissions is one of the big issues in global warming debate. However Before you start controlling by putting the carbon in the ground, you first have to put lawyers in a room to argue. After a year that saw billions of dollars in spent around a variety of carbon capture and storage pilot projects, the focus in 2010 will shift from press conferences and engineering discussion to court cases and conference tables.

EPA Updates Mobile Source Emissions Model
December 27, 2009 01:31 PM - Roger Greenway, ENN

The US EPA is the source of most air quality impact assessment models used in the US for regulatory purposes, such as predicting the potential impacts from proposed stationary sources of air pollutants and mobile sources such as motor vehicles. Since motor vehicle emissions vary with regulatory changes in required emission level, it is important that impact modeling be performed with the most up-to-date models. EPA recently announced that an updated version of the Motor Vehicle Emission Simulator (MOVES) model – MOVES2010 – is now available for use to estimate air pollution from cars, trucks, and other on-road mobile sources. The model can also calculate the emissions reduction benefits from a range of mobile source control strategies, such as inspection and maintenance programs and local fuel standards.

The Internet is Becoming a Great Place to Check on the Environmental Status of Facilities
December 26, 2009 10:42 AM - Roger Greenway, ENN

The Internet is becoming a great tool for getting information on facilities that are emitting air pollution, discharging water pollution, and generating hazardous wastes. In the past, this information was difficult for the public to access, and in some cases either was not made available to the public, or required a Freedom of Information Act filing to obtain. This is changing as more states and the federal government is making this information available on line. The latest effort comes from the U.S. Environmental Protection Agency (EPA) which has released enforcement results for fiscal year 2009, and has developed a new Web-based tool and interactive map that allows the public to get detailed information by location about the enforcement actions taken at approximately 4,600 facilities.

Obama Frustrated with Outcome of Copenhagen Climate Talks
December 25, 2009 10:47 AM - Thomas Schueneman, Global Warming is Real

Despite near instantaneous condemnation of his role in the culmination of the COP15 climate negotiations last week, president Obama voiced his frustration over the course those negotiations took and accord that resulted from them. Speaking with Jim Lehrer on Wednesday, president Obama said that "people are justified in being disappointed about the outcome in Copenhagen."

EPA Curbs Ship Emissions
December 24, 2009 12:04 PM - Andy Soos, ENN

The US EPA has finalized a rule setting tough engine fuel standards for large US flagged ships, a major milestone in the agency's coordinated strategy to slash harmful marine diesel emissions. The regulation harmonizes with international standards and will lead to significant air quality improvements throughout the country. "There are enormous health and environmental consequences that come from marine diesel emissions, affecting both port cities and communities hundreds of miles inland. Stronger standards will help make large ships cleaner and more efficient, and protect millions of Americans from harmful diesel emissions," said EPA Administrator Lisa P. Jackson. "Port communities have identified diesel emissions as one of the greatest health threats facing their people especially their children. These new rules mark a step forward in cutting dangerous pollution in the air we breathe and reducing the harm to our health, our environment, and our economy."
