Report highlights positive effects of US diesel emissions reduction program

Clean diesel grants aimed at cleaning up old diesel engines have greatly improved public health by cutting harmful pollution that causes premature deaths, asthma attacks and missed school and workdays, according to a new report by the US Environmental Protection Agency (EPA). Since its start in 2008, the Diesel Emission Reduction Act (DERA) program has significantly improved air quality for communities across the country by retrofitting and replacing older diesel engines.

Clean diesel grants aimed at cleaning up old diesel engines have greatly improved public health by cutting harmful pollution that causes premature deaths, asthma attacks and missed school and workdays, according to a new report by the US Environmental Protection Agency (EPA). Since its start in 2008, the Diesel Emission Reduction Act (DERA) program has significantly improved air quality for communities across the country by retrofitting and replacing older diesel engines.

Diesel exhaust significantly contributes to the formation of dangerous soot and smog and is likely to increase the risk of cancer. The funding from the program has helped clean up approximately 335,200 tons of nitrogen oxides (NOx) and 14,700 tons of particulate matter (PM), which are linked to a range of respiratory ailments and premature death. The program has also saved 450 million gallons of fuel and prevented 4.8 million tons of carbon dioxide (CO2) emissions – equivalent to the annual CO2 emissions from more than 900,000 cars. EPA estimates that clean diesel funding generates up to US$13 of public health benefit for every US$1 spent on diesel projects.

“EPA is making a visible difference in communities that need it most through the funding of cleaner trucks, buses, trains, and other heavy equipment,” said Janet McCabe, the EPA’s acting assistant administrator for the Office of Air and Radiation. “The report on DERA’s impact offers striking evidence that this program is succeeding in providing Americans with cleaner air where they live and work while also cutting the pollution that fuels climate change.”

    Pollution has more than one solution
    Professor Alexander Baklanov of the World Meteorological Organization talks to Colin Sowman about the difficulties of reducing urban pollution. The inhabitants of Beijing have recently been suffering pollution levels 20 times the World Health Organisation’s recommended limit while the European Union is revitalising its efforts to implement and enforce air quality standards. Almost inevitably much of the clean-up efforts are likely to focus on traffic planners and engineers.

    Siemens to develop infrastructure for London's ULEZ
    Siemens will develop software for London’s Ultra Low Emission Zone (ULEZ) with the intention of ensuring that the necessary infrastructure is in place for when it goes live in April 2019. The zone will require vehicles, barring some exceptions, to meet exhaust emissions standards or pay a daily charge when travelling into central London. Work will now commence over the next 12 months to allow the software to be deployed for service preparation activities leading up to the scheme. The ULEZ is intended

    Green Light WIM
    Beginning in the 1990s, Oregon was one of the first US states to use weigh-in-motion scales and transponder-based systems to enable trucks to avoid having to stop at weigh stations. Its Green Light preclearance system soon became a model for similar deployments throughout the country. Today, Green Light annually weighs and screens 1.6 million trucks as they approach 21 Oregon weigh stations and it preclears 1.5 million of them.
