The low-emission vehicle (LEV) standard requires vehicle manufacturers to deliver passenger cars, trucks, and SUVs that produce lower greenhouse gas emissions and other pollutants for sale in Minnesota. The policy will implement two clean cars standards to reduce vehicle emissions.
Traffic-related air pollutants can lead to a short-term loss of power and long-term reduction in lifetime for proton exchange membrane fuel cells (PEMFC). A team from Daimler, ZBT GmbH and Forschungszentrum Jülich has now systematically analyzed the influence of NO, NO 2 , NH 3 and SO 2 on automobile fuel cells under realistic conditions.
Scott Fruin, Neelakshi Hudda and colleagues noted that past research has measured pollution from air traffic before, but most of these studies only sampled air within a couple of miles, at most, from airports. The emissions from LAX are likely not unique on a per-activity basis.
Green automobile technology has a unique history that affects strategies for both navigating “patent pollution” (i.e. Because green automobile technology has its roots in the 19 th century, there is prior art relating to clean automobiles going back more than one hundred years.
The study also shows that the proportion of gaseous aromatic compounds—apart from benzene—in hydrocarbon emissions is two to three times greater in pollution plumes in Paris than in Los Angeles, even though the total quantity of hydrocarbons emitted in Los Angeles remains considerably greater than in Paris.

ARB staff plans to cover four topic areas in the workshop: Mass reduction.
Up to 13 million metric tons of plastic enter the ocean each year, threatening marine life and polluting shorelines, according to Pew Charitable Trusts, a global nongovernmental organization. For more than two decades, Ford has used recycled plastics not collected from oceans to produce various parts for automobiles.
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. 10 ) of urban air, a fraction known to be enriched with non-tailpipe constituents.
EPA found Clean Air Act violations at Tesla’s automobile manufacturing plant in Fremont, Calif. This settlement aligns with EPA’s National Compliance Initiative (NCI), Creating Cleaner Air for Communities by Reducing Excess Emissions of Harmful Pollutants. Under the settlement, Tesla agreed to pay a $275,000 penalty.
Mayor Hidalgo described her anti-pollution plan, which will be considered by the Conseil de Paris (the assembly governing the city) on 9 February, to the weekly Le Journal du Dimanche (leJDD) on 6 December. The CCFA has five members: Alpine, Citroën Automobiles, Automobiles Peugeot, Renault and Renault Trucks.).
Catalytic converters have been used in the US since the 1970s as a way to clean up pollutants from vehicle exhaust. In the catalytic process, rare metals such as platinum, are used in a chemical reaction to convert carbon monoxide and other pollutants to non-toxic carbon dioxide, nitrogen, and water. —Yong Wang. Resources.
These new compounds were not previously known to exist, and raise additional concerns about the health impacts of heavily-polluted urban air or dietary exposure. PAHs form naturally as the result of almost any type of combustion, from a wood stove to an automobile engine, cigarette or a coal-fired power plant. Staci Simonich.
A study led by MIT researchers, focused on New York City, suggests that using mobile-phone data to track people’s movement provides an even deeper picture of exposure to pollution in urban settings than by studying air-quality levels in fixed places. Their open-access paper is published in the ACS journal Environmental Science & Technology.
million units in the months through September, as lower-priced automobiles have become more affordable for better-off Chinese people, according to data released by the China Association of Automobile Manufacturers (CAAM) on Oct. Sales of domestically-manufactured autos rose 36 percent year on year to reach 13.14
The researchers cite studies that show during the lifetime of an automobile tire. These findings led the researchers to conclude that even at current environmental levels of tire-related pollution, which are expected to increase, aquatic ecosystems may be experiencing negative impacts.

Fiat Chrysler Automobiles, part of the Stellantis group, was sentenced Monday to pay a U.S. 300 million criminal penalty over diesel engines that polluted more than they were allowed by regulations. The Detroit federal court's decision is a result of a Justice Department investigation and includes a fine of $96.1
However, as required by the Clean Air Act, automobile manufacturers began installing onboard refueling vapor recovery (ORVR) technologies in 1998, making gas stations’ systems increasingly redundant. Since 2006, all new automobiles and light trucks (pickups, vans and SUVs) are equipped with ORVR systems.
Fiat Chrysler Automobiles (FCA), IVECO (a brand of CNH Industrial) and ENGIE (Global Energy Player) are broadly collaborating to promote natural gas vehicles and infrastructure in Europe. Transportation is responsible for 22% of CO 2 emissions in the world (and even 30% in Europe); 95% of the energy consumed by this sector comes from oil.
Offering extended range, rapid refueling and zero tailpipe emissions, the heavy-duty vehicle addresses the limitations of pure battery-electric trucks for short and regional-haul freight markets while providing an economically-viable replacement for polluting diesel engines.
In states already in the program, the automobile industry has successfully met the required percentage. Advancing these strategies will reduce carbon pollution, improve air quality and help support fuel savings for the average consumer. Each year, manufacturers must meet a ZEV credit amount that is based on average annual sales.
