I recently read a brilliant book, Malcolm Gladwells, Revenge of the Tipping Point that alerted me to the fact that just five per cent of the passenger vehicles on the road produce more than half of all the pollution in the air. Pollution would drop by the same amount as the 10 per cent shift. Do let us know in the Comments.)
Some in the health care industry also think these transitions could simultaneously support peoples health by reducing pollution. The companys estimates suggest such trips have one-tenth the pollutants of those made with gas-powered ambulances. Some automobiles can operate on 85% ethanol.
A new study by researchers from Stockholm University concludes that automobile tires may be a potential previously unknown source of carcinogenic dibenzopyrenes—a type of high molecular weight polycyclic aromatic hydrocarbon (PAH)—to the environment. Automobile tire rubber in general consists of approximately 40?
The companies are joining efforts to implement the carbon-negative UBQ thermoplastic ( earlier post ) into auto parts manufactured by Motherson Group for the automotive industry. Adding as little as 10% UBQ GHG to a part can immediately transform it into a carbon-neutral product. Polymers typically emit 1.9
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. Borbon, A., Gilman, W.
Since 2005, when major greenhouse-gas emitters among the Kyoto signatories were issued caps on their emissions and permitted to buy credits to meet those caps, there has been more than $300 billion worth of carbon transactions. The approval process for carbon offsets has two goals. THE APPROVAL PROCESS.
million in Carbon Recycling International (CRI). Geely’s CRI investment and work with renewable methanol is similar to the approach Audi is taking with its own e-fuels projects—producing very low carbon liquid or gaseous fuels using only renewable energy, water and CO 2. —Li Shufu, Chairman of Geely Group.

Each year, manufacturers must meet a ZEV credit amount that is based on average annual sales.
We believe the fastest way to lower greenhouse gases in the transportation sector is to offer drivers lower carbon choices that meet their needs. At every price point and with multiple powertrains, we can put more people in cleaner automobiles across North America to have the greatest near-term impact on total carbon emissions.
Among the direct transportation-related provisions in the extensive package are a low-carbon fuel standard for all transportation fuels; financial support for large scale demonstrations of electric vehicles; and financial support for automakers retooling plants to make electric vehicles. Carbon Capture and Sequestration.
So I ask this Congress to send me legislation that places a market-based cap on carbonpollution and drives the production of more renewable energy in America. And I believe the nation that invented the automobile cannot walk away from it. It begins with energy. Millions of jobs depend on it. Scores of communities depend on it.
This newly developed ENSs could improve low-temperature automobile exhaust treatment. Meanwhile, hydrocarbons, such as propylene (C 3 H 6 ) and propane (C 3 H 8 ) are typical automobile exhaust gas pollutants and must be converted to carbon dioxide (CO 2 ) and water (H 2 O) before they are released as exhaust.
alumina supports along with a small amount of lanthanum oxide can efficiently turn the carbon monoxide in automotive exhaust into carbon dioxide at temperatures as low as 40 ?Celsius, Most of the pollutants from a modern automobile are emitted during the first 30 seconds of starting a car, when the catalyst is still being warmed.
These high-carbon emitting fuels power our cars, trucks and airplanes, but pollute the air, pose widespread health risks and threaten the stability of the earth’s climate. California’s environmental laws and policies have created an effective framework for cutting down our use of petroleum fuels.
catalyst synergistic reaction is more effective at low temperatures; the hybrid reaction reduces the temperature required to achieve the same level of DRE (destruction and removal efficiency) for hydrocarbon (HC) pollutants when compared to the temperature of the reaction under the influence of the catalyst alone. —Kang et al.
ORVR systems are carbon canisters installed in vehicles to capture gasoline vapors evacuated from the gasoline tank before they reach the pump nozzle. Gasoline-rich vapors in an empty automobile fuel tank are forced out when liquid gasoline is pumped into the tank. Stage II vapor recovery systems.
Rainforest Action Network (RAN) held a rally in Sacramento Thursday outside the lobbying offices of the Association of Automobile Manufacturers to protest their continuing lawsuit against California's greenhouse gas legislation. The great zero-carbon emitting, zero-particulate emitting, zero-petroleum consuming electric cars.
“The most significant impact that can be made in reducing CO 2 emissions from automobiles in the coming decades is reducing the average weight and engine size of vehicles.” The report identifies a number of myths surrounding low-carbon road transport: “Diesel cars are highly polluting.” Myth Busting.
Emissions analysis commissioned by the Australian Automobile Association (AAA) has found an affected VW diesel vehicle to be using up to 14% more diesel after being recalled for the mandated emissions system fix. The tests showed a reduction in emissions of NO x carbon monoxide and particulate matter occurred after the recall fix.
Many pollution control and renewable-energy applications require precious metals that are limited—there isn’t enough platinum to supply the millions and millions of automobiles driven in the world. Mullite is not only easier to produce than platinum, but also better at reducing pollution in diesel engines. Kyeongjae Cho.
The researchers analyzed extensive satellite and ground-based measurements of nitrogen oxides and carbon monoxide. They found that levels of pollutants that can contribute to the formation of ground-level ozone, or smog, have failed to continue a fairly steady decline as estimated by the US Environmental Protection Agency.
Because when burnt, algae biofuel only releases CO 2 recently removed from the atmosphere via photosynthesis as the algae grew, Mazda considers its development to be critical to achieving the carbon-neutrality of cars powered by the internal combustion engine. Microalgae biofuel has numerous positive attributes as a renewable liquid fuel.
