The EPA Federal Test Procedure, commonly known as FTP-75 for the city driving cycle, are a series of tests defined by the US Environmental Protection Agency (EPA) to measure tailpipe emissions and fuel economy of passenger cars (excluding light trucks and heavy-duty vehicles).
Emissions from all non-road engines are regulated by categories. [49] In the United States, the emission standards for non-road diesel engines are published in the US Code of Federal Regulations, Title 40, Part 89 (40 CFR Part 89). Tier 1–3 Standards were adopted in 1994 and was phased in between 1996 and 2000 for engines over 37 kW (50 hp ...
The regulation took into account various national cycles such as World-wide Heavy-Duty Certification procedure (WHDC) and World-wide Motorcycle Test Cycle (WMTC). [7] It also took into consideration the 1958 Agreement and the 1998 Agreement, those of Japan and the United States Environmental Protection Agency (US EPA) Standard Part 1066. [7]
Vehicle emissions inspection station in Wisconsin. Arizona – biennially, in Phoenix and Tucson metro areas only, depending on age and type of vehicle. [28]California – biennially for all vehicles from out-of-state, regardless of age; and all vehicles made after 1975 which are more than six years old in all or some zip codes in 41 out of 58 counties.
Areas that are rated include greenhouse gas emissions per passenger mile, the use of low emissions technology, the use of alternative fuels, purchase of carbon offset, participation in CST training programs, and the energy efficiency of other places associated with the company, such as the home office. [1] The CST gives eRatings on a vehicle basis.
Engine manufacturer Cummins Inc. has agreed to pay a $1.675 billion penalty for allegedly installing "defeat devices" on approximately 1 million pickup trucks to cheat emissions tests.
Pennsylvania cannot enforce a regulation to make power plant owners pay for their planet-warming greenhouse gas emissions, a state court ruled Wednesday, dealing another setback to the centerpiece ...
Emission test results from individual vehicles are in many cases compiled to evaluate the emissions performance of various classes of vehicles, the efficacy of the testing program and of various other emission-related regulations (such as changes to fuel formulations) and to model the effects of auto emissions on public health and the environment.
