In California’s Los Angeles Basin, levels of volatile organic compounds (VOCs) pollutants have decreased by about 98% since the 1960s, even as area residents now burn approximately three times as much gasoline and diesel fuel. The reason is simple: cars are getting cleaner. The difference was amazing.
Heavy-duty trucks, such as the ones targeted under this funding, are the single largest source of NO x and diesel PM in the Valley, and are critical to ensuring that goods are moved throughout the State and nation. The District is currently working on reaching attainment for the federal 8-hour ozone and PM 2.5 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.
The Pennsylvania Department of Environmental Protection (PA DEP) awarded $516,637 in clean diesel grants to four organizations. The clean diesel program’s goal is to improve air quality by decreasing emissions from diesel-powered transit bus and school bus fleets.
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. VIP is part of the state’s overall plan to cut toxic diesel emissions 85 percent by 2020.
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. These trucks run cleaner and quieter, and will help to make the local environment healthier for future generations.
Additional diesel PM reductions in 18 major CA railyards with five new locomotive measures. While we are pleased to have already reduced diesel emissions at the rail yards, it’s not enough. Accelerating the introduction of cleaner new Tier 4 interstate line-haul locomotives to operate in California and other western states (2015-2025).
Commercial workboat engines are staying in service more than two times longer than predicted by the US Environmental Protection Agency (EPA), according to new research from the Diesel Technology Forum (DTF) and Environmental Defense Fund (EDF). This report underscores that more, older engines remain in service today.
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.
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%.
Ships, especially ocean-going vessels, are powered by very large diesel engines that generate a tremendous amount of pollution impacting air quality onshore. One finding was that container ships encountered off the Port of Houston, where no clean-fuel use is required, emitted four times as much sulfur dioxide.
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. Industry is already increasing the use of alternatives to petroleum diesel, including renewable diesel and biodiesel.
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.
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. Click to enlarge.
The first study to conduct a comprehensive evaluation of lifetime exposure to new technology diesel exhaust (NTDE)—i.e., exhaust from heavy-duty diesel engines meeting EPA 2007 and later emissions requirements—has found no evidence of carcinogenic lung tumors. Earlier post.) Earlier post.)
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).

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.
We feel confident that our technology is ready to usher in the benefits of lower emissions, and lead the industry’s push toward cleaner mobility. hp diesel engine. hp diesel engine. —Dan Singleton, CEO and co-founder of Transient Plasma Systems.
The program funds projects to encourage the development and use of new technologies and alternative and renewable fuels, including electricity, natural gas, biomethane, hydrogen, and gasoline and diesel substitutes, such as cellulosic ethanol (derived from woody materials, including agricultural waste), and biodiesel from waste grease.
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.
This finding is in stark contrast to previously released CE-CERT data and a recently released report by the California Air Resources Board that found heavy-duty diesel trucks emitted higher levels of NO x than their certification standards in the same duty cycles. g/bhp-hr emission target and averaged between 0.014 and 0.002 g/bhp-hr.
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. Damages from electricity generation. Coal accounts for about half the electricity produced in the US.
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). Peak urban diesel buses showed the best overall energy consumption and GHG emissions per PKT.
And the grid is getting cleaner and more renewable every year. Simply put, the study found what advocates of electric transportation have long held to be true: as regards greenhouse gases and pollution generally speaking, the worst electricity is still better than petroleum.
Key Steps to Cleaning Southern California’s Air Diesel Class 8 trucks run seemingly tail-to-nose from the Ports of Long Beach and Los Angeles to the Inland Empire in Southern California. Last mile trucks like Amazon’s are moving to EVs Almost all of those trucks run on diesel, but change is coming. Even the U.S.
These reductions have come from strong efforts to reduce on-road vehicle emissions, especially diesel particulate matter. Finally, the State should provide incentives to accelerate market transitions to cleaner technologies that foster significant system-wide solutions to cut emissions of SLCPs.
ARB staff reviewed four offset protocols and recommends that they be approved as part of this regulatory package: (1) the Urban Forest Projects Protocol; (2) the US Ozone Depleting Substances Projects Protocol; (3) the Livestock Manure (Digester) Projects Protocol; and (4) the US Forest Projects Protocol. Offset Protocols.
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.
Almost $12 million of Louisiana’s share was put aside to exchange 351 diesel buses owned by 16 local school boards. Almost half the new buses are fueled by cleaner-burning propane or compressed natural gas; the others are cleaner-burning diesel engines. Net-zero carbon emissions by 2050 are the governor’s goal.
Reducing emissions of black carbon soot and ground-level ozone would quickly make a considerable dent in the climate change problem and would also contribute to public health and protect crop yields, according to an essay in the September/October issue of Foreign Affairs. Besides a danger to breathe, ozone lowers crop yields.
A single proposal may target multiple fleets, fleet types and/or diesel emission reduction solutions. Reducing emissions from diesel engines remains one of the most important air quality challenges facing the country, according to the EPA. million tons of NO x , which contribute to the formation of ozone and additional fine particles.
