Rice University team links PM2.5 and ozone levels with cardiac arrest

Green Car Congress

A team from Rice University and the Houston Fire Department EMS has found a direct correlation between out-of-hospital cardiac arrests (OHCA) and levels of air pollution and ozone. Ensor is a professor and chair of Rice’s Department of Statistics, and Raun is a research professor in Rice’s Department of Statistics.

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. Ozone is the reactive form of oxygen that contains three atoms per molecule (O 3 ) rather than the normal two. Khadraoui, S. &

Study: 25% EV adoption would save US $17B annually from avoided climate change & pollution damages

Green Car Congress

Vehicle electrification in the United States could prevent hundreds to thousands of premature deaths annually while reducing carbon emissions by hundreds of millions of tons. Results show that in more aggressive scenarios—i.e., Resources.

Study finds fleet switch from PFI to GDI engines will result in net reduction in global warming

Green Car Congress

A new study quantifying emissions from a fleet of gasoline direct injection (GDI) engines and port fuel injection (PFI) engines finds that the measured decrease in CO 2 emissions from GDIs is much greater than the potential climate forcing associated with higher black carbon emissions from GDI engines. —Saliba et al. versus 6.3 ± 1.1
