Study finds that replacing older, highly polluting school buses could lead to 1.3 million fewer daily absences annually

Green Car Congress

Replacing all of the oldest, highly polluting school buses in the US could lead to 1.3 Even relatively short commutes on school buses can dominate students’ daily air pollution exposures. Applying their results nationwide, the researchers extrapolated that replacing all pre-2000 model school buses would lead to more than 1.3

Latest GHG Inventory shows California remains below 2020 emissions target; much steeper rate of GHG reductions required

Green Car Congress

The data shows a slight increase in overall emissions from the previous year, and a slight decline in emissions from transportation, which is the state’s main source of both GHGs and air pollutants. CARB has approved additional measures to reduce emissions of greenhouse gases from super pollutants that must also be reduced significantly.

California Air Resources Board posts revised draft of strategy to reduce “Super Pollutants”

Green Car Congress

The California Air Resources Board (CARB) has posted a revised draft of California’s proposed Short-Lived Climate Pollutant (SLCP) Strategy. SLCPs are a category of pollutants which remain in the atmosphere for a relatively brief period, but have global warming potentials that are much higher than those of CO 2.

Study finds that worldwide SO2 emissions rose between 2000-2005 after decade of decline; China, shipping topped growth

Green Car Congress

Global sulfur dioxide (SO 2 ) emissions peaked in the early 1970s and decreased until 2000, with an increase in recent years due to increased emissions in China, international shipping, and developing countries in general, according to a new analysis appearing in the open access journal Atmospheric Chemistry and Physics.

California ARB Report Finds Fine Particle Air Pollution Responsible for 9,000 Premature Deaths in State Each Year; Based on US EPA Peer-Reviewed Study

Green Car Congress

Approximately 9,000 people in California are estimated to die prematurely each year as a result of exposure to fine particle pollution, according to a new report issued by the California Air Resources Board (ARB). Fine particle pollution, smaller than 2.5 A causal relationship indicates the highest level of scientific certainty.
