The most important air quality challenges facing the country today is reducing emissions from diesel engines Environmental Protection Agency which is abbreviated as EPA has established the national clean diesel campaign(NCDC)for promoting the reduction of diesel emission. It serves as a multi-pronged approach. The campaign will work aggressively to reduce the emission of diesel engines. NCDC includes innovative programs in such a way to address millions of diesel engines already in use and many regulatory programs to address new diesel engines. The dominant fuel used by many commercial transportation sectors is diesel. But they emit large quantity of nitrous oxide, particulates matters and air pollutants. Diesel engines contribute a lot to the movement of goods across the nation. They mainly help us in carrying millions of children to school everyday. While they are critical to nation’s economy, the exhausts from the diesel engines acts as pollutants and has a huge impact on human health and our surroundings. The health problems include asthma, lung cancer, cardiac and respiratory problems. The city of Albuquerque’s vehicle pollution management division works to protect the emission in that country.

The national clean diesel campaign has introduced regulatory programs such as 2008 locomotive and marine diesel rule,2007 heavy-duty highway engine rule and the clean air non road diesel rule. The goal of these innovative programs is to introduce cost-effective strategies fro reducing emission. The EPA’s verification program helps to verify and evaluate the emission reduction capabilities. The process includes several reviews and testing to quantify the emission reductions. A toolkit has been created by EPA for supporting the state and local governments in their efforts for reducing the diesel emissions. Approximately $156 million has been awarded by EPA for national clean diesel funding assistance projects. The eligible entities are regional, local, state or port agency with jurisdiction over transportation or air quality and non-profit organizations or institutions which provide educational services for the reduction of emission. At least 50% of this funding is dedicated to public fleets and some private fleets like school buses and refuse haulers.

The smart way clean diesel finance program will receive approximately $30 million. This fund will support innovative programs for clean diesel financing. The state clean diesel grant program will receive approximately $88 millions. This fund is available to support clean diesel grant and loan programs administered by the state and District of Columbia.
The national clean diesel emerging technologies will approximately an amount of $20 million. This will support for the development and commercialization of emerging technologies that reduces the emission. All these technologies have been developed by the NCDC to maintain, regulate and reduce the emission.

EPA has also announced an awarded of $498,796 to the city of Portland in January 2009.These grants assist Oregon’s clean diesel initiative to reduce the harmful emissions. Sections 792 of the Energy policy act of 2005 authorize EPA to contribute grants to fund the costs of retrofit technology to reduce emissions. Thus the EPA has proposed many innovative technologies to reduce emission of diesel from engines. These technologies are to be implemented usefully to prevent the emissions which exist as a serious problem for human health and environmental issues.
