The funds will be used to retire a Tier 0 diesel locomotive and to replace it with a zero-emission switching locomotive using advanced hydrogen technology.
In a new report released by the California Air Resources Board, scientists from the University of California at Davis and Berkeley estimate that rising temperatures from climate change will increase ozone levels in California’s major air basins. Our study reveals that climate change and regional air pollution are intertwined problems.
The approved 2014-2015 Investment Plan Update for the Alternative and Renewable Fuel and Vehicle Technology Program will help reduce greenhouse gas emissions from the transportation sector, which accounts for about 40% of California''s carbon emissions.
Researchers at the University of California, Irvine and other institutions have conducted a statistical analysis of pollution exposure and yields from 1980 to 2015 on a key sector making up about 38% of the state’s total agricultural output: perennial crops such as almonds, grapes, nectarines, peaches, strawberries and walnuts.
Results from a new study by researchers at the University of California Irvine support a growing body of scientific literature indicating that sensitive populations, including children, certain ethnic groups and people of lower socioeconomic status, are more vulnerable to the effects of high exposures to traffic-related air pollution.
A study by researchers at UC Davis suggests that a properly designed vehicle scrappage (i.e., Cash for Clunkers”) program could maximize greenhouse gas emissions savings by using fuel-economy based eligibility requirements rather than age-based requirements. Earlier post.). The one exception is the US CARS program.
Transportation is the single largest emitter of greenhouse gases in California – accounting for over one third of the state’s overall emissions. To reach our emissions reduction goals, we need to be strategic as we deploy new vehicles and new transportation modes. —Senator Skinner.
Awardees represent the top one to two percent of environmentally-responsible SmartWay carriers that conduct freight operations with lower emissions and less energy. Since 2004, SmartWay Partners have avoided emitting more than 72 million metric tons of carbon pollution, while saving more than 170 million barrels of oil and $24.9
A study led by researchers at UC Berkeley has found that diesel exhaust forms about seven times more secondary organic aerosols (SOA) than gasoline exhaust for the same mass of unburned fuel emissions and, given emission factors, can be expected to form 15 times more SOA than gasoline per liter of fuel burned.

Switching from diesel fuel to natural gas may hold advantages for the US heavy-duty trucking fleet, but more needs to be done to reach the full environmental benefits, according to a new white paper released by the Institute of Transportation Studies at the University of California, Davis, and Rice University. Environmental considerations.
Black carbon is part of a group of pollution sources known as Short-Lived Climate Forcers (SLCFs), including methane gas and ozone, which are produced on earth. Cappa, a professor of engineering at the University of California, Davis, and Timothy B. Earlier post.). Led by principal investigators Christopher D.

Current ozone levels in the San Joaquin Valley are predominantly caused by local emissions, but as air quality standards become lower, any contribution from global ozone levels needs to be understood. An ozonesonde is a balloon which measures ozone from the surface to more than 10 kilometers above the ground.
The staff of the California Air Resources Board has posted the expert review reports of the Zero Emission Vehicle (ZEV) technical analysis. Instead don’t we want to know what percentage of the on-road fleet are ZEVs in 2050, as this will help determine the GHG emissions? 2009 Zero Emission Vehicle (ZEV) Review.
A study by Jonn Axsen and Ken Kurani from the Institute of Transportation Studies, UC Davis, estimates electricity and gasoline use under three recharging scenarios. Two recent studies explore different aspects of the use, potential impact and valuation of PHEVs. Increasing the percentage of PHEVs in the vehicle.
Four years ago, the professor at the University of California at Davis and a team of engineering students created a plug-in vehicle. clip) Despite some concerns that plugging in might stress the electric grid, or actually increase carbon dioxide emissions by relying on coal-fired power plants, Kramer is not worried.
Director at the ETA, Andrew Davis, said: “Car makers can build green cars, but they need us to buy them. EU regulation is striving to cut the CO2 emitted by cars to an average figure of 130 g/km by 2015.
At the same time, we’ve been able to take old, polluting cars off the road and help consumers purchase fuel efficient vehicles.”. The scheme has not been without controversy though; one UC Davis transportation economist Christopher Knittel criticized the scheme as a costly way to reduce carbon emissions.
Heres our three-paragaph summary and a link to the first of several postings on the subject at CalCars-News : July 2007 EPRI-NRDC Definitive Study: PHEVs Will Reduce Emissions If Broadly Adopted The EPRI-NRDC studies finally give an environmental stamp of approval to PHEVs. Three more points: Both reports match up well with previous studies.

Nichols met with officials of China’s leading automakers and battery manufacturers in an effort to expand cooperation and accelerate deployment of zero-emission cars, trucks and buses. Discussions with the companies centered on plans for developing new models of zero-emission vehicles and support needed to enter the US market.
The objections they raised for years -- "no one is interested, no one would plug in, the technology is too complex, the benefits are minimal, its just shifting the pollution from the tailpipe to the smokestack, theres no demand for these cars" -- still show up occasionally, but are by and large history.
The team used a combination of climate, air quality, and epidemiological models to assess future air pollution deaths in a changing climate under Representative Concentration Pathway 4.5 (RCP W/m 2 before 2100 without overshoot by employment of a range of technologies and strategies for reducing greenhouse gas emissions.). Hong et al.

In California, mobile sources of diesel emissions, such as trucks and construction equipment, are one of the largest sources of fine particulates. Estes will pay $35,000 to the University of California Davis Extension to implement a state-approved training program for out-of-state trucking firms on compliance with the rule.
and UC-Davis Emeritus and Catherine JJ DeMauro. The alternative-fuel car evolved to reduce exhaust emissions and other problems derived from burning fossil fuels. Since it can operate on 100% biofuel, it is the means for achieving new goals recently set for reducing the use of fossil fuels and cutting the net emission of CO 2 to zero.
Finally, the proposal delineates a land use and transportation infrastructure layout that enhances efficiency and community, while minimizing energy use, water pollution, and nonrenewable resource consumption. LLMs reduce total energy use for transportation, and thus reduce petroleum consumption and greenhouse gas emissions, Delucchi notes.
