million gallons of fuel exceeding the standard was supplied for 48 days in late 2010 at Chevron’s Montebello terminal and another 660,000 gallons of non-compliant fuel was supplied for four days in April 2011 at the Richmond terminal. An estimated 3.75 Chevron fully cooperated with ARB in this matter and took steps to correct the violations.

These reductions came while emissions of fine particles were also 92% lower than the 2010 standard 99% lower than 2004 emissions.
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. Even though the CO 2 enhancements over background were comparable in the two years, about 25 ppm in 2002 and 35 ppm in 2010, the ?CO/?CO2 CO2 ratio for this flight track segment decreased from 24.5
Combining the control of criteria pollutants and greenhouse gas emissions into a single coordinated package of standards is a new approach to ARB’s motor vehicle standards. ARB has held four public technical workshops on the proposed rulemaking since 2010; a fifth is scheduled for 19 July. These are: 2 March 2010.

This shows that the decreases in sulfur dioxide are a direct consequence of the application of the EU requirements. was allowed. (the
The French Government will reduce the purchase tax incentives for lower carbon cars and increase the penalties for high-pollution vehicles beginning in January. France’s bonus-malus scheme provides financial rewards for those who purchase or lease a new vehicle emitting less CO 2 g/km while taxing more heavily polluting cars.
Rapid increases in pollution may be as harmful to the heart as sustained high levels, according to new research published in the European Journal of Preventive Cardiology. However, this study investigated whether rapid increases in pollution increase the risk of heart attack, independently of an absolute threshold.
million at the end of 2010, leading to widespread congestion and hampering the city’s environmental protection. Research has shown that more than three quarters of total air pollution comes from vehicle carbon monoxide and hydrocarbon emissions in large cities including Beijing, Shanghai and Guangzhou.
