California statewide GHG emissions dropped below the 2020 GHG Limit in 2016 and have remained below the 2020 GHG Limit since then. in 2018 (2000-2018 average year-over-year increase is 6.8%), continuing the increasing trend as they replace Ozone Depleting Substances (ODS) being phased out under the 1987 Montreal Protocol.
The engine was certified in the fall of 2016 by the EPA and the California Air Resources Board (CARB) to 0.02 g/bhp-hr, which is 90% cleaner than EPA’s current NO x emission standard and 90% cleaner than the cleanest available diesel engine. g/bhp-hr emission target and averaged between 0.014 and 0.002 g/bhp-hr.
While current state and federal measures are on target to reduce toxic diesel locomotive emissions 65% or more by 2020, additional measures recommended by ARB staff would ultimately provide up to 85% or greater emissions reductions within the rail yards over the same period, resulting in cleaner air for nearby residential neighborhoods as well.
In addition to ozone and particulate matter, the other pollutants are lead, carbon monoxide, nitrogen dioxide and sulfur dioxide. The authors emphasized that their findings do not specifically address an individual’s health risk or the personal benefits of cleaner air, but rather assess population level health impacts.

The “Kigali Amendment” resulting from the annual Montreal Protocol Meeting of Parties in October 2016 in Kigali, Rwanda targets phasing down the production of HFCs globally. More than three-quarters of HFC emissions in California come from the use of refrigerants in the commercial, industrial, residential, and transportation sectors.
As the trend toward cleaner technologies with reduced exhaust emissions continues through the use of catalytic converters, diesel particulate filters (DPF), and improved fuels and engines, non-exhaust PM will soon surpass exhaust emissions and may well become dominant by 2020 both in terms of emissions and contributions to air quality.
million shares of an almost $3 billion settlement in 2016 between the U.S. Almost half the new buses are fueled by cleaner-burning propane or compressed natural gas; the others are cleaner-burning diesel engines. Nitrogen oxides and sulfur dioxides are precursor chemicals that, combined with sunlight, create ground-level ozone.
Mandatory regional criteria pollutant reduction targets will be established in the 2016 State Implementation Plans (SIPs) with expected reductions on the order of 90% below 2010 levels in the South Coast and similar reductions in the San Joaquin Valley by the year 2032.
