Port of Los Angeles rolls out $82.5M hydrogen fuel cell electric freight demonstration; Toyota fuel cell technology

Green Car Congress

The Port of Los Angeles and its partners rolled out five new hydrogen-powered fuel cell electric vehicles (FCEV) and introduced two hydrogen fueling stations. At the same time, they will measure the reduction of nitrogen oxide, particulate matter, and greenhouse gas emissions, as well as other pollutants. Under the $82.5-million

A scatter plot of CO, as a tracer for pollution, versus CO 2 , as a tracer for the amount of combustion, for 2002 and 2010. CO2 ratio for this flight track segment decreased from 24.5 Even on the most polluted day during a research mission in 2010, we measured half the VOCs we had seen just eight years earlier. ppbv/ppmv to 10.7

Urban CO2 Domes May Enhance May Increase Ozone and PM, With Accompanying Increase in Mortality

Green Car Congress

While the existence of higher CO 2 levels overs cities—CO 2 domes—has been known for more than a decade, their effects on local air pollution has up to now not been explored. His study estimates that local CO 2 emissions may increase premature mortality by 50-100 and 300-1,000/year in California and the US, respectively. Mark Jacobson.

Study on Greenhouse Gas Emissions from Global Cities Highlights Importance of Geophysical and Technical Factors

Green Car Congress

An international study of 10 global cities found that a balance of geophysical factors (climate, access to resources, and gateway status) and technical factors (power generation, urban design, and waste processing) determine the greenhouse gas emissions (GHGs) attributable to cities. t e CO2/cap.)

Stanford Professor Urges EPA to Include Black Carbon in Endangerment Finding

Green Car Congress

Because eliminating BC emissions almost immediately removes atmospheric BC whereas eliminating CO 2 emissions removes atmospheric CO2 over only many decades, eliminating BC can immediately slow down the loss of Arctic ice, whereas eliminating GHG emissions can slow loss only over a longer period. However, both BC and GHG controls are needed.
