A new study provides the most detailed picture available to date of the global, regional, and local health impacts attributable to emissions from four transportation subsectors: on-road diesel vehicles; other on-road vehicles; shipping; and non-road mobile engines such as agricultural and construction equipment.

The eventual CTI rulemaking will establish new, more stringent emission standards for NO x and other pollutants for highway heavy-duty engines. This rulemaking will also offer opportunities to streamline and improve certification procedures to reduce costs for engine manufacturers.

for $1,990,650—the largest penalty to date related to clean air violations for the state’s Ocean-Going Vessel At Berth Regulation. The auxiliary engines covered under this regulation power the electricity and other onboard operations during a vessel’s visit, which can run from less than one day to several days.

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. From 2007 to 2017, US NO x emissions dropped by more than 40%. EPA last revised NO x standards for on-highway heavy-duty trucks and engines in January 2001.

This is in contrast to the conventional mobile AC system, where the cabin air is directly cooled by the refrigerant HFC-134a, which is ozone safe but has a high GWP. The refrigerant never enters the passenger compartment and instead stays in the engine area. Only the coolant circulates through the interior air conditioning unit.

Higher octane fuels can lead to higher compression ratios which in turn can lead to more efficient gasoline engines and reduced fuel consumption. With turbocharged gasoline engines, there is a double benefit: higher compression ratios and increased boost. Currently, the Clean Air Act limits the volatility of gasoline to 9.0
