GREENHOUSE GAS EMISSION STANDARDS
COMPLYING WITH GREENHOUSE GAS EMISSION STANDARDS
Emissions standards in the US are established by the Environmental Protection Agency (EPA). Federal regulations serve as a minimum requirement for the nation, although individual
Californiaâ€™s EPA, however, has had to contend with severe pollution in Los Angeles, so it has received special permission from the government to create its own legislation. Other states may either choose to follow the federal or California standards. States that have elected to follow the California system include: Arizona, Connecticut, Maine, Maryland, Massachusetts, New Jersey, New Mexico, New York, Oregon, Pennsylvania, Rhode Island, Vermont, Washington, and Washington D.C. The first federal emissions standards for non-road diesel fuel engines over 37 kW (50hp) began in 1994 and were set to be phased in between 1996-2000. Other requirements released over the next decade focused on advanced engine design as a method of greenhouse gas emissions reduction. In 2004 another regulation determined the level of acceptable particulate matter (PM) and mono-nitrogen oxide (NOx)

This will affect the transportation of rental equipment, which may have future impact on equipment rental coverage.
would reduce GHG emissions and improve fuel economy for first commercial trucks and then passenger vehicles.
CERTIFICATION: Manufacturers must submit a Pre Model Year (PMY) Report to be considered for certification. The report must go to both the EPA and the NHTSA. The contents of the report will include subconfiguration target and fleet standards, test group and fleet certification results, production volumes, joint approvals for innovative technology, certification statements for the EPA and NHTSA, and credit plans. The main purpose for the PMY Report is to provide these agencies with evidence that manufacturers are

will need to reduce gallons of fuel consumed and emissions per ton-mile by 20%. This will save approximately 4 gallons of fuel for every 100 miles travelled. Heavy-duty trucks and vans will have to reduce grams of CO2 emissions per mile and gallons of fuel consumed per mile by 15%, saving about 1 gallon of fuel per 100 miles travelled. Vocational vehicles (buses, delivery trucks, garbage trucks, etc.) will have to reduce gallons of fuel consumed and emissions per ton-mile by 10%, saving roughly 1 gallon of fuel per 100 miles travelled. Ton-mile figures are calculated by dividing gallons of fuel consumed and grams of CO2 emissions per mile by tons of freight hauled. More precise targets exist within every category depending on the type of vehicle.
TARGET VEHICLES: Heavy duty vehicles, starting in model year 2014
EXEMPT VEHICLES: Medium-duty passenger vehicles
