  • EPA releases new mobile source emissions model

    WASHINGTON - 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. EPA will ...

  • New model for estimating ship emissions to guide policy

    EU-supported research has established a new model to calculate air pollution emissions from ships. Its calculations could create a database that lists emissions per ship type and size as well as by country. Emissions from ships have increased alongside the growth in international trade. Without the intervention of legislation, EU maritime emissions of both nitrogen oxides and sulphur dioxide ...

  • Latest emission control technology could eradicate harmful air pollution hotspots

    Switching to the best available emission control technologies could eliminate 99% of particulate matter pollution ‘hotspots’, a new study suggests. The researchers reached this conclusion by expanding the local-scale capabilities of an existing computer model that estimates the effects of air pollution policies and control measures. Particulate matter (PM) pollution has been linked ...

  • Real Time Air Dispersion Modelling

    WKC reach a major milestone in the implementation of a facility-wide REAL-TIME AIR DISPERSION MODELLING system at a major refinery in the Sultanate of Oman; WKC has successfully combined its air quality consultancy experience with a sophisticated real-time modelling software package to provide a powerful tool in the management of impacts to ambient air quality. ...

  • Air traffic management to balance CO2 emissions and noise pollution

    Speed constraints for aircraft are put in place, at some airports, to minimise noise pollution in local areas, however, such practices can be very fuel-inefficient. New research has now shown that relaxing departure speed limits could substantially reduce CO2 emissions, while maintaining acceptable noise levels. The aviation industry is a major contributor to emissions of greenhouse ...

  • Climate change and health costs of air emissions from biofuels and gasoline

    The report’s erroneous finding that modern corn ethanol actually increases greenhouse gas (GHG) emissions relative to gasoline is completely predicated on the baseless assumption that additional corn demand for increased ethanol production will cause conversion of large amounts of grassland enrolled in the Conservation Reserve Program (CRP). Thus, like several other highly controversial studies ...

  • Greater efforts to reduce ammonia emissions needed to meet air pollution targets

    Levels of particulate matter (PM) in the atmosphere are linked to ammonia emissions. However, reducing ammonia emissions only as far as targets set out by the Gothenburg Protocol will not necessarily ensure compliance with EU PM limits, according to a new study. Greater reductions in ammonia emissions would reduce the number of days when PM limit values are exceeded, the researchers found. In ...

  • A&WMA and WEF Call for Odors and Air Emissions Abstracts for 2008 Conference

    Pittsburgh, PA – The Air & Waste Management Association (A&WMA), in partnership with the Water Environment Federation (WEF), has issued a call for abstracts for the 2008 WEF/A&WMA Odors and Air Emissions specialty conference, to beheld April 6-9, 2008 in Phoenix, AZ. Submissions will be accepted until Friday, June 1, 2007. As communities grow in size and population, more municipal, ...

Held in cooperation with the North Carolina Water Environment Association, this bi-annual conference will focus on the effective management of odor and air emissions from ...

  • Emission Control - Geoengineering to remove Carbon Dioxide from the Air

    The notion of global warming was first mooted by French scientist and mathematician Joseph Fourier in 1824 and discovered by John Tyndall in 1860, he and later, Svante Arrhenius, pinned down the mechanisms. It is perhaps deceived wisdom that Arrhenius was the first to suggest that Sweden might once again be able to grow tropical fruit, such as bananas with a little geo-engineering, but Alexander ...

  • California Air Board Requires Steep Emissions Cuts By 2018

    DIAMOND BAR, California, October 2, 2007 (ENS) - The California Air Resources Board has approved a multi-faceted plan to improve air quality throughout the state. It will require replacement or cleanup of the dirtiest trucks on the road, and a program for out-of-state trucks doing business in California. It also requires cleanup of large off-road equipment, ships and locomotives. ...

  • AQE 2015 to focus on ways to improve air quality and emissions monitoring

  • Asian air emissions increases ozone over western North America

    Increases in tropospheric ozone levels above western North America during springtime are due to eastward air flows across the Pacific Ocean, with the largest increases associated with air that comes from south and east Asia, according to a recent study. In the troposphere, the lowest layer of the atmosphere, high levels of ozone are considered to negatively affect human health and crop ...

  • Calculating emissions from shipping

    Shipping is a significant source of atmospheric pollutants, which contribute to climate change and have negative effects on human health and the environment. A new study has applied detailed methods to estimate global fuel consumption from international shipping, including for the first time, an estimation of emissions from the global fleet while in port. Developing appropriate policies to ...
