Nigh Smog, Soot, and Other Air Pollution from Transportation
What is smog?
The term "smog" was beginning used effectually 1950 to describe the combination of smoke and fog in London. Today, information technology refers to a mixture of pollutants made up mostly of ground level ozone.
Air pollution emitted from transportation contributes to smog, and to poor air quality, which has negative impacts on the health and welfare of U.S. citizens. Pollutants that contribute to poor air quality include particulate thing (PM), nitrogen oxides (NOx), and volatile organic compounds (VOCs).
The transportation sector is responsible for:
- Over 55% of NOten total emissions inventory in the U.Southward.
- Less than 10% of VOCs emissions in the U.Due south.
- Less than 10% of PM2.5 and PM10 emissions in the U.Southward.
(NOTE: This value does non account for the substantial amount of PM that is formed in the atmosphere from gaseous mobile source emissions)
(Reference: Multi-Pollutant Comparison)
The transportation sector also contributes to emissions of air toxics, which are compounds that are known or suspected to crusade cancer or other serious wellness and ecology effects. Examples of mobile source air toxics include benzene, formaldehyde, and diesel particulate affair.

Programs to Reduce Smog, Soot, and Other Air Pollution from Transportation
EPA implements national programs and standards for fuels and vehicles that reduce air pollution including smog, soot, and toxic pollutants, and spur investments in clean vehicle and engine technology. EPA programs to reduce emissions from transportation sources have resulted in less smog and soot, significantly better air quality and better wellness for Americans. By 2030, EPA air quality emissions standards for vehicles are projected to annually prevent:
- xl,000 premature deaths
- 34,000 avoided hospitalizations
- 4.8 million work days lost
Double-decker Standards
Passenger vehicles are regulated past EPA under calorie-free duty vehicle programs. EPA ready stringent emissions standards for passenger vehicles, besides as limits on the amount sulfur, a naturally occurring contaminant, in gasoline. Limiting sulfur in gasoline allows emissions reductions technologies like catalysts to exist significantly more effective in reducing nitrogen oxides and other pollutants.

Heavy Duty Diesel fuel Engine Standards
EPA has a multifariousness of standards to reduce emissions from heavy duty diesel vehicles and engines. These include standards for tractor-trailers, large buses, construction and agricultural equipment, diesel fuel engines in boats and ships, and fifty-fifty locomotives. These standards have significantly reduced emissions of diesel frazzle and improved public wellness.
- Regulations for smog, soot, and other air pollution from commercial trucks & buses
- Regulations for emissions from heavy equipment
- Regulations for emissions from locomotives
- Regulations for emissions from marine vessels
National Clean Diesel fuel Plan
The Make clean Diesel Program offers funding in the form of Diesel Emissions Reduction Human action grants and rebates also as other back up for projects that protect human health and improve air quality by reducing harmful emissions from diesel engines. Between 2009 and 2013, almost 60,000 engines were retrofitted or replaced through our plan. EPA estimates that these projects will result in $xi billion in health benefits from reduced air pollutant emissions over the lifetime of afflicted engines.

SmartWay
Freight transportation is a large contributor to air pollution and climate change. SmartWay helps the freight transportation manufacture improve supply concatenation efficiency to reduce air pollution from their operations. The 3 core elements of the Smartway Program include transport partnerships between shippers and carriers and the EPA, brand sensation of fuel-saving technologies, and global collaboration.

Emission Command Areas
On March 26, 2010, the International Maritime Organisation (IMO) designated coastal areas of U.South., Canadian and French waters as an Emission Control Expanse (ECA). Within the ECA, large ocean going vessels must adhere to stricter emissions and fuel standards resulting in significantly less air pollution beingness emitted.
The improvements to air quality that result from the North American ECA are expected to have large benefits to public health. By 2022 the ECA will preclude up to 14,000 premature deaths annually and reduce respiratory symptoms for near five million people each yr in the U.Due south. and Canada.

Ports Initiative
The Ports Initiative is working to develop and implement environmentally sustainable port strategies through partnerships between EPA and ports. The plan identifies opportunities to reduce air pollution and ameliorate air quality in port communities, and reduce the carbon pollution that contributes to climatic change while supporting jobs and the economic system. EPA is supporting these efforts through a number of programs, including funding through the Diesel fuel Emission Reductions Human action.

Air Toxics
EPA standards for transportation sources and voluntary programs accept resulted in significant reductions in mobile source air toxic emissions. Mobile source chancy air pollutants accept been cut in half since 1990. With additional fleet turnover, EPA expects that emission to be cut past 80 per centum by the twelvemonth 2030.
Learn more well-nigh the standards and programs that accept contribute to these reductions including:
- Regulations to reduce mobile source pollution
- National Make clean Diesel Program
Ensuring Compliance and Conducting Research
To accomplish the benefits of our regulations, EPA must ensure that the standards set for vehicles, engines and fuels are being met. One way EPA achieves this is by surveillance testing of cars, trucks and engines at our state-of-the-art National Vehicle and Fuel Emissions Laboratory. The laboratory also provides critical resource to accomplish the vehicle and engine testing work necessary to set vehicle and engine emissions standards and fuel standards.

- Compliance and fuel economy information for vehicles and engines
- Vehicle and fuel emissions testing
Resources for Local and State Transportation
In states and communities throughout the country, state and local leaders are seeking to balance their air quality, climate, and transportation goals. EPA provides useful data, tools, and links to resources that place emission reduction strategies, national policies, regulations, incentive-based programs, funding sources, calculators, and other types of assistance to help states and local areas accomplish their air quality and transportation objectives. This site also includes EPA regulations and guidance to support state I/Grand, fuel, and transportation conformity programs.
