Study measures the effect of regional change in clouds caused by ships’ emissions; masking GHG warming

Green Car Congress

This puffy line is not just exhaust from the engine, but a change in the clouds that’s caused by small airborne particles of pollution. Pollution from ships creates lines of clouds that can stretch hundreds of miles. The difference helps explain how much industrial pollution influences clouds. NASA Earth Observatory.

CE Delft Study Finds Lower Highway Speed Limits Could Result in Significant Reductions in CO2 from Road Transport; Encouraging Modal Shifts and Land Use Changes

Green Car Congress

Based on the law of constant travel time budget, the average travel time elasticity of the amount of kilometres equals -1, (average for all modalities) (Van Wee, 1998; Pfleiderer, 2003). Fuel consumption of a car increases at higher speeds, the main reason being that with increasing speed the wind resistance increases exponentially.

Study of lead isotopes provides insight into aerosols transport from Asia to US

Green Car Congress

About a third of the airborne lead particles collected at two sites in the San Francisco Bay Area came from Asia, a finding that underscores the far-flung impacts of air pollution and heralds a new way to learn more about its journey across vast distances. They found that a median value of 29% of the lead particles were of Asian origin.

Next 10 report finds California must increase GHG reductions to 4.9%/year through 2030 to meet target

Green Car Congress

The largest one-year emissions drop California has ever achieved was at the height of the Great Recession in 2009, when climate pollution fell 6.1%. lower than 2008 and 2003, respectively. Data from the report illustrate that California now must reduce emissions by an average of 4.9% lower and 8.3%

PPIC Survey Finds Californianss Support for Policies to Curb Warming Slips With Economy and Budget Crisis; Partisan Split Widens

Green Car Congress

For only the second time since PPIC began asking the question in 2003, more Californians support expanding oil drilling off the coast than oppose it (51% favor, 43% oppose), the same as last year (51% favor, 45% oppose). Energy sources and automobile efficiency. Air quality. Californians’ views about air quality have seen a significant shift.

Obama sets goal of reducing US oil imports by 1/3 by 2025; domestic and Western Hemisphere production, natural gas, biofuels, electric vehicles, fleet purchases

Green Car Congress

Obama noted that last year, US oil production reached its highest level since 2003 and that for the first time in more than a decade, imported oil accounted for less than half the liquid fuel consumed. We have to discover and produce cleaner, renewable sources of energy with less of the carbon pollution that threatens our climate.

MIT Report Finds Natural Gas Has Significant Potential to Displace Coal, Reducing Greenhouse Gas Emissions; Role in Transportation More Limited

Green Car Congress

The first two reports dealt with nuclear power (2003) and coal (2007). The introduction of large intermittent power generation from, for example, wind and solar, will have specific short and long term effects on the mix of generation technologies.
