New statistical method to detect ozone pollution hot spots and monitor instrument failure; combining PCA and MEWMA

Green Car Congress

A new statistical method developed by researchers at KAUST (King Abdullah University of Science and Technology, Saudi Arabia) can detect abnormal ozone levels within large bodies of monitored data. Sun and her colleagues also hope to apply their data analysis techniques to dust pollution, another major environmental issue in Saudi Arabia.

CARB releases results of multi-year E15 study; multiple air quality benefits with slight reduction in fuel economy

Green Car Congress

The Multimedia Evaluation (MME) of E15 looked at the effects of increased ethanol content on exhaust emissions in 20 vehicles—all model year 2016 or newer. The test fleet showed statistically significant effects for some pollutants, but not for others. The study used two fuels—an E10 and E15.

California ARB: GHG emissions fell below 1990 levels for first time in 2016; down 13% from 2004 peak; transportation emissions up 2%

Green Car Congress

The California Air Resources Board (CARB) announced that greenhouse gas emissions in California in 2016 fell below 1990 levels for the first time since emissions peaked in 2004—a reduction roughly equivalent to taking 12 million cars off the road or saving 6 billion gallons of gasoline a year.

European Parliament votes to phase out conformity factor for new car emissions under real driving conditions by Sep 2022

Green Car Congress

As of September 2022, new cars must meet EU limits on NO x emissions under real driving conditions to comply with air pollution limits, the European Parliament has voted. The EU is the first region in the world to use real driving emissions (RDE) tests to measure such pollutants emitted by vehicles while driven on the road.
