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

Green Car Congress

The Manufacturers of Emission Controls Association (MECA) released a new report quantifying a county level MOVES emissions inventory in the continental US (CONUS) 48 states and subsequent air quality modeling report of a potential scenario should the US EPA Cleaner Trucks Initiative (CTI) be finalized as a national program at the emission limits proposed by CARB in their heavy-duty omnibus regulation.

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. EPA expects that any update to the standards will result in significant mobile source NO x reductions, which will aid communities across the country in the attainment of ozone and particulate matter standards.

The US Environmental Protection Agency (EPA) is proposing to retain, without changes, the existing, more stringent 2015 National Ambient Air Quality Standards (NAAQS) for ozone. The standards, established in 2015, are currently set at 70 parts per billion (ppb), in terms of a 3-year average of the annual fourth-highest daily maximum 8-hour average ozone concentrations.

VOCs, primarily emitted from the tailpipes of vehicles, are a key ingredient in the formation of ground-level ozone which, at high levels, can harm people’s lungs and damage crops and other plants. The reason is simple: cars are getting cleaner. The 98% drop in VOCs in the last 50 years does not mean that ozone levels have dropped that steeply; the air chemistry that leads from VOCs to ozone is more complex than that.
