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. The US has made major reductions in NO x emissions, but it’s been nearly 20 years since EPA updated these standards.
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.

BASF has launched UpCore, a new service providing a cost-effective and sustainable technology upgrade from a standardozone converter to an ozone-VOC (volatile organic compounds) converter for cleaner and healthier aircraft cabin air. The air at high altitude contains significant levels of ozone.
Reducing emissions from mobile sources is key to the San Joaquin Valley meeting federal ambient air quality standards. The District’s successful truck incentive programs have repowered, retrofitted, or replaced more than 7,300 heavy-duty trucks with cleaner alternatives. standards.
The US Environmental Protection Agency (EPA) has awarded $5 million to the Southern Alliance for Clean Energy (SACE) to help Southern truckers and small businesses to buy cleaner big rigs. About 8 million are exposed to air quality that violates the federal standards for particulate matter.
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.
Alternative-fuel technology company ROUSH CleanTech has developed the first available propane autogas engine certified to California Air Resources Board’s (CARB’s) optional low oxides of nitrogen emissions standard for heavy-duty engines with 0.02 The engine is 90% cleaner than the current Environmental Protection Agency’s most stringent 0.2
CARB approved the State Strategy for the State Implementation Plan ( State SIP Strategy ), which describes CARB’s commitment for further reducing vehicle emissions needed to meet federal air quality standards over the next 15 years. The Board also approved the South Coast Air Quality Management District’s comprehensive air quality plan.
The California Air Resources Board approved changes to an existing $28 million financial assistance program this week that will significantly help more California independent truckers qualify for the purchase of a cleaner-running vehicle.
Each of the four recipients will match a percentage of the grant amount with their own funds to purchase compressed natural gas-powered vehicles; retrofit diesel engines with cleaner technology; replace older, more polluting diesel buses with cleaner diesel buses; or purchase hybrid electric-powered buses.
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.
Use of electric vehicles would achieve greater reductions in GHG emissions, corresponding to the rate that the electric grid becomes cleaner, through greater reliance on renewables and low- and non-emitting generation. This research points to the importance of two fundamental and parallel trends in energy and the environment.
In “Estimated Excess Morbidity and Mortality Caused by Air Pollution above ATS Recommended Standards, 2011-2013,” published online in the August edition of Annals of the American Thoracic Society , researchers report on the annual health benefits of meeting more protective standards recommended by the ATS for O 3 and PM 2.5.
Compared to the 2010 “Business as Usual” scenario—which includes all adopted emission control measures for the South Coast—NO x levels must be reduced by 65% and by 75% to meet the 2023 and 2032 ozonestandards, respectively. California’s Climate Protection Strategies do not help meet NAAQS Standards.
The US EPA issued an Advance Notice of Proposed Rulemaking (ANPR) for the Cleaner Trucks Initiative (CTI). The eventual CTI rulemaking will establish new, more stringent emission standards for NO x and other pollutants for highway heavy-duty engines. EPA is seeking input from the public and interested stakeholders.
Cummins Westport ISL G near-zero (NZ) natural gas engine ( earlier post ) meets and exceeds the certification standards during a full range of duty cycles. g/bhp-hr, which is 90% cleaner than EPA’s current NO x emission standard and 90% cleaner than the cleanest available diesel engine.
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. Per capita GHG emissions in California have dropped from a 2001 peak of 14.0 tons per person to 10.7 tons per person in 2018, a 24% decrease.
The results, published in an open-access paper in the journal Science , suggest that the focus of efforts to mitigate ozone formation and toxic chemical burdens need to be adjusted, the authors suggested. Recent research suggests that adverse human health effects occur below current US standards for both PM 2.5 McDonald et al.
ABuilding on the proposed stronger ambient air quality standards for ozone ( earlier post ), EPA will develop a strategy for a cleaner and more efficient power sector, with strong emission reduction goals for SO 2 , NO x , mercury and other air toxics.
Emissions from automobile exhaust systems have decreased in recent years due to the introduction of cleaner fuels and new control technologies on internal combustion engines, as well as increases in numbers of hybrid and electric vehicles.
A longer service life reduces the fleet’s turnover rate to cleaner, lower-emitting engines, therefore increasing future-year emission estimates. Most tugs are operating in locations near America’s ports which do not meet current federal health-based air quality standards.
The cap-and-trade program also works in concert with other measures, such as standards for cleaner vehicles, low-carbon fuels, renewable electricity and energy efficiency, and complements and supports California’s existing efforts to reduce smog-forming and toxic air pollutants.
Eligible diesel emission reduction solutions include verified emission control technologies such as retrofit devices, cleaner fuels, and engine upgrades, verified idle reduction technologies, verified aerodynamic technologies and low rolling resistance tires, certified engine repowers, and/or vehicle or equipment replacement.
The approach described is designed to meet simultaneously federal air quality standards; achieve greenhouse gas emission reduction targets; reduce petroleum consumption; and decrease health risk from transportation sources through 2030. Under current control programs (left) and under the Cleaner Technologies and Fuels scenario (right).
The cap-and-trade joins a suite of other major climate program measures including standards for ultra-clean cars (Advanced Clean Cars, earlier post ), low-carbon fuels (Low Carbon Fuel Standard, earlier post ) and renewable electricity. the destruction of existing stores of ozone-depleting substances in the U.S. Earlier post.)
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.
A new report from the US Environmental Protection Agency (EPA) finds that air pollution at US ports can be reduced significantly at all port types and sizes through a variety of strategies and cleaner technologies. national ambient air quality standards (NAAQS).

In a separate action, the California Energy Commission approved $4,979,070 through the current ARFVT program to projects that will support increased numbers of cleaner, alternative fuel vehicles on California roadways.
Colorado has voted to approve a new standard on the adoption of electric vehicles (EVs), with an additional goal set for 2032 and new guidance for increasing EV sales beginning in 2027. Coloradans want low- and zero-emissions vehicles because they help them get where they’re going while breathing cleaner air and saving money.
The committee that wrote the report focused on monetizing the damage of major air pollutants—sulfur dioxide, nitrogen oxides, ozone, and particulate matter—on human health, grain crops and timber yields, buildings, and recreation. miles per gallon will lower emissions and damages for every vehicle mile traveled.
The study exposed laboratory rats 80 hours a week, for up to 30 months, to emissions from a heavy-duty diesel engine meeting 2007 US EPA standards using new filters and other control technology. Countries like China are already moving toward implementing the ultra-low sulfur diesel fuel that is required for these new cleaner technologies.
On their 100+ mile round trip, these trucks burn diesel fuel that damages the ozone, spews out noxious particulates that seek-out lungs and eyes along with oxides of nitrogen that help create smog, along with other nasty—and toxic—unpleasantness. How much cleaner could the air be if, instead of 50 trucks, it is 500, 1,000 or 10,000.
Automakers agree on common plug to recharge electric vehicles by Darren Murph , posted Apr 19th 2009 at 4:24PM Just hours after General Motors put forth a proposal for a standardized plug for electric vehicles , in flies this. The US standard is 120V@60hz the UK standard is 240V@50Hz. Same goes for video cables.
Many of the strategies employed to reduce GHG emissions will also work to meet the national ambient air quality standard for ozone in 2032. Major transportation related policies already in place are: The Low Carbon Fuel Standard (LCFS). Background. —Draft Scoping Plan Update.
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. From 2017 to 2019, ozone concentrations fell 4%. During that same time, national average ozone concentrations have dropped 25%. Background.
