In California’s LosAngeles 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. ppbv/ppmv to 10.7 Source: Warneke et al. Warneke, C.,
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. —Brian McDonald, corresponding author.
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. The agreement includes $2.5 million in match funding.
Improving access to cleaner forms of transportation, like electrified public transport and active commuting by cycling and walking, would not only bring down NO 2 levels, but would also reduce asthma, enhance physical fitness, and cut greenhouse gas emissions. Achakulwisut et al.
Kairos Ventures is the LosAngeles venture capital firm funding TPS. 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. it is vital that the transportation world continues to improve the combustion engine technology.
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.
In addition to ozone and particulate matter, the other pollutants are lead, carbon monoxide, nitrogen dioxide and sulfur dioxide. The authors emphasized that their findings do not specifically address an individual’s health risk or the personal benefits of cleaner air, but rather assess population level health impacts.
Key Steps to Cleaning Southern California’s Air Diesel Class 8 trucks run seemingly tail-to-nose from the Ports of Long Beach and LosAngeles to the Inland Empire in Southern California. How much cleaner could the air be if, instead of 50 trucks, it is 500, 1,000 or 10,000.
