EPA seeks to adopt emission standards for large commercial aircraft
The U.S. Environmental Protection Agency (EPA) is proposing to adopt new air pollution standards for engines used primarily in large commercial aircraft, including 737s, 747s, and 767s. The proposal would reduce ground-level nitrogen oxide emissions by an estimated 100,000 tons nationwide by 2030. Exposure to nitrogen oxide emissions can cause and aggravate lung diseases and increase ...

New Article Published: ECO PHYSICS CLD 899 Y Used for Measurement of Ambient Air Pollution
NOx: Traffic Dramatically Underestimated as Major Polluter Traffic contributes more to nitrogen oxide emissions in Europe than previously thought. This is the result of a current study carried out by scientists from the University of Innsbruck. The research team headed by Thomas Karl shows that even newer air quality models underestimate traffic related nitrogen oxide pollution by up to a factor ...

Tougher Petroleum Refinery Standards Proposed to Protect Air Quality
EPA is proposing to reduce emissions from new, modified, or reconstructed process units at petroleum refineries. The proposed amendments would update the existing standards of performance for petroleum refineries. Under the proposal, new, modified or reconstructed units would be required to add emission controls that reflect demonstrated improvements in emission control technologies, in addition ...

Nitrogen oxide emissions still a major problem in Europe
Air pollution emitted from sources such as traffic, industry and households is still above internationally agreed limits in many European countries, according to data published today. The accompanying report from the European Environment Agency (EEA) confirms an initial assessment published earlier this year, showing 12 EU Member States exceeded limits under the National Emissions Ceilings (NEC) ...

China exports air pollution to the North America’s West Coast
Many of the measures taken by federal, state and local administrations in the United States to improve air quality on its West Coast are being thwarted by air pollution blowing across from China. This is the conclusion of research conducted by Wageningen University in association with the Royal Netherlands Meteorological Institute (KNMI) and the American space agency NASA, recently published in ...

EU to exceed nitrogen oxides emission ceiling, mostly due to road transport
The EU-27 and its Member States must meet legally binding limits for four air pollutants set by the National Emission Ceilings Directive (NEC Directive) to protect human health and the environment. The annual status report released today by the European Environment Agency (EEA) shows that while EU-27 emissions for three air pollutants are projected to meet the ceilings, nitrogen oxides (NOx) ...

Multi-pollutant approach needed to halt soil degradation
A new study highlights the need for new policies to stop the rise of nitrogen oxide emissions in China. The researchers suggest that the positive impact of policies to reduce sulphur dioxide emissions are not enough in themselves to avoid soil acidification, as they will be outweighed over the next decade by the impact of nitrogen emissions. Soil acidification is a type of soil degradation that ...

KSR Bitterfeld-Wolfen
The plant is to combust approx. 270,000 t/year of dewatered and pre-dried municipal sewage sludge, making it one of the largest plants of its kind in Germany. The staged fluidised-bed incineration system used for this project is a technology owned by KMT and designed with an integrated post-incineration chamber and a secondary air system for achieving optimum control of the combustion process. ...

Travelling slower reduces fuel consumption and nitrogen oxides emissions of ships
Ships that reduce their speed use less fuel, which lowers costs for shipping companies. The slow steaming practice also cuts nitrogen oxides (NOx) emissions. A study found that ships travelling on four European routes lowered their NOx emissions by 12% during the economic crisis of 2008/2009. Shipping continues to be a major way of transporting goods, however, and as the global economy recovers ...

Germany`s VW: New C02 problems with 800,000 vehicles
Germany's Volkswagen, already reeling from the fallout of cheating on U.S. emissions tests for nitrogen oxide, said Tuesday that an internal investigation has revealed "unexplained inconsistencies" in the carbon dioxide emissions from 800,000 of its vehicles - a development it said could cost the company another 2 billion euros ($2.2 billion). The investigation was undertaken by the company ...

Beijing power plants to curb emissions for Olympics
Beijing's power plants are set to slash their emissions in a bid to clean up the skies in time for this year's Olympic Games, according to reports in local media. The five power plants based in the city are fuelled mainly by coal and provide a third of Beijing's electricity and all of its thermal energy. However, local media have reported that the Huaneng Beijing Thermal Power Plant has put in ...

EPA Awards Grant to Reduce Respiratory Hazards from Diesel Emissions in Puerto Rico
Earlier this year, the U.S. Environmental Protection Agency (EPA) awarded a $1.4 million Diesel Emissions Reduction Act (DERA) grant to the University of Puerto Rico – Medical Sciences Campus. The grant provides funding to replace a number of old heavy duty drayage trucks. The university is also developing seminars and resources for diesel vehicle owners and the general public in Puerto ...

Modelling marine exhaust emissions in the Baltic Sea
A new tool used to investigate exhaust emissions of marine vessels has been developed and applied to shipping in the Baltic Sea. The Baltic Sea is a busy maritime region with 3500-5000 ships operating in the area every month. Emissions from shipping contribute significantly to atmospheric pollution, leading to health and environmental problems. In May 2006, the Baltic Sea was the first area ...

EPA Proposes Refined Emissions Test to Improve Safety, Reliability, and Efficiency of Existing Power Plants
EPA is proposing further options to change the emissions test used to determine if the New Source Review (NSR) permitting program would apply when an existing power plant makes a physical or operational change. Congress established the NSR program as part of the 1977 Clean Air Act Amendments and modified it in the 1990 Amendments. NSR is a preconstruction permitting program that maintains air ...
