MECA emissions inventory & air quality modeling shows potential benefits of national cleaner trucks initiative at CARB limits

Green Car Congress

On 6 March 2020, the California Air Resources Board (CARB) proposed to set an intermediate FTP NO x emissions limit of 50 mg/bhp-hr in model years 2024-2026 with a final FTP standard of 20 mg/bhp-hr in 2027, representing a 90% reduction below today’s standard of 200 mg/bhp-hr.

EPA launches Cleaner Trucks Initiative to update NOx standards for heavy-duty trucks

Green Car Congress

The US Environmental Protection Agency (EPA) has launched the Cleaner Trucks Initiative (CTI) to further decrease NO x emissions from on-highway heavy-duty trucks and engines. It is estimated that heavy-duty trucks will be responsible for one-third of NO x emissions from the transportation sector in 2025.

Reducing Black Carbon Emissions and Ground-Level Ozone Would Provide Immediate Benefit Against Climate Change

Green Car Congress

Reducing emissions of black carbon soot and ground-level ozone would quickly make a considerable dent in the climate change problem and would also contribute to public health and protect crop yields, according to an essay in the September/October issue of Foreign Affairs. Besides a danger to breathe, ozone lowers crop yields.

EPA issues ANPR on Clean Trucks Initiative, seeking input from public and stakeholders

Green Car Congress

The US EPA issued an Advance Notice of Proposed Rulemaking (ANPR) for the Cleaner Trucks Initiative (CTI). EPA said it is closely following the technical work initiated by the California Air Resources Board (CARB) to update the CARB heavy-duty vehicle and engine programs under a Heavy-Duty NO x Omnibus proposal.

EPRI-NRDC report finds widespread vehicle electrification and a cleaner grid could lead to substantial cuts in GHG by 2050

Green Car Congress

Widespread adoption of electric transportation, including electrification in the off-road sector, could lead to substantial reductions in greenhouse gas (GHG) emissions and could modestly improve air quality, according to a new analysis released by the Electric Power Research Institute (EPRI) and the Natural Resources Defense Council (NRDC).

Study finds that current approach to limiting wintertime pollution may initially backfire

Green Car Congress

The processes that create ozone pollution in the summer can also trigger the formation of wintertime air pollution, according to a new study from researchers at the University of Colorado Boulder and NOAA, in partnership with the University of Utah. Regulations and cleaner technologies have steadily improved air quality in the United States.
