Later years should show additional improvements as greater fleet turnover occurs. The modeled 2028 base year 8-hour ozone design values were found to be above the 70 ppb NAAQS for 75 monitoring locations. Metropolitan areas and highway corridors will see the greatest reduction in ozone due to the strategy, with reductions of up to 6.5
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.
Emissions from heavy-duty vehicles are primarily under the regulatory jurisdiction of state and federal government, and voluntary incentive programs are critical to transitioning fleets to the next generation of cleaner technologies and achieving reductions needed to meet air quality standards. standards.
The new CNG fleet will replace older diesel-powered trucks. One of the more lasting contributions we can make in our community is to protect the environment by reducing ozone-forming emissions wherever possible. Three out of every four trucks in our local fleet will be powered by natural gas by the end of this calendar year.
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. —lead author Carsten Warneke, Ph.D., Warneke, C., de Gouw, J. Holloway, J.
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.
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 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.
The engine is 90% cleaner than the current Environmental Protection Agency’s most stringent 0.2 Last year, we introduced a propane autogas engine that was 75% cleaner than the EPA’s emissions standard. grams per brake horsepower-hour (g/bhp-hr). Earlier post.). g/bhp-hr heavy-duty engine standard. billion Volkswagen settlement funds.
For heavy-duty vehicles, the State SIP Strategy calls for combustion engine technology that is effectively 90% cleaner than today’s standards. Approximately 70% of the reductions needed to meet the ozone standard in the South Coast in 2031 would come from existing or proposed regulatory actions. emissions by more than 20%.
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. As transportation gets cleaner, those other sources become more and more important. McDonald et al. Click to enlarge.
Workplace, fleet and multi-unit dwelling projects will be given priority. $5 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. 4 million to emerging opportunities. .
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 ozone standards, respectively. An 80% reduction of GHG emissions is targeted for 2050, relative to 1990 levels.
ARB staff developed this strategy using a multi-pollutant scenario planning tool ( Vision 2.0 ) that quantifies changes in ozone and PM 2.5 precursor emissions; GHG emissions; petroleum usage; and diesel toxics emissions as various technologies become widespread in vehicle and equipment fleets. Vision 2.0 Click to enlarge.
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. In 2030, adding plug-in hybrid electric vehicles to these fleets could yield even more NO x and PM 2.5 Click to enlarge.
FTA’s Low-No Program supports transit agencies in purchasing or leasing low- or no-emission buses and other transit vehicles that use technologies such as battery electric and fuel-cell power to provide cleaner, more efficient transit service in communities across the country.
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.
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. Post Office will be converting a sizeable portion of its fleet of electric vans.
And the grid is getting cleaner and more renewable every year. Annual GHG emissions reductions were significant in every scenario combination of the study, reaching a maximum reduction of 612 million metric tons in 2050 (High PHEV fleet penetration, Low electric sector CO2 intensity case). billion metric tons.
Mikhail Chester and Arpad Horvath inventoried on-road, rail, and air travel to determine energy consumption, greenhouse gas (GHG) emissions, and criteria air pollutant (CAP) emissions (excluding PM, lead, and ozone due to lack of data). 83% of rail passenger kilometers are performed by metropolitan systems (with Amtrak serving the remaining).
Many of the strategies employed to reduce GHG emissions will also work to meet the national ambient air quality standard for ozone in 2032. Since its launch in 2011, the regulation has generated a multitude of unique approaches for cleaner fuels. million zero emission vehicles on its roads by 2025.
A single proposal may target multiple fleets, fleet types and/or diesel emission reduction solutions. million tons of NO x , which contribute to the formation of ozone and additional fine particles. Funding will be in the form of cooperative agreements or grants.
