Since MY 2004, fuel economy and CO 2 emissions have improved in eleven out of thirteen years. Since 2004, CO 2 emissions have decreased 23%, or 104 g/mi, and fuel economy has increased 29%, or 5.6 miles per gallon, slightly higher than MY 2016, and a record high overall. Estimated Real-World CO 2 and Fuel Economy. Source: EPA.

Mexico’s Secretariat of Environment and Natural Resources (SEMARNAT) has proposed new heavy-duty vehicle emissions standards, aligned with current standards in place in the rest of North America and in the European Union. The current limit values in Mexico are equivalent to Euro IV or EPA 2004 standards. emissions in urban areas.

Researchers at Peking University have developed a new methodology to model black carbon (BC) emissions from diesel and gasoline motor vehicles. Black carbon is a key short-lived climate change forcer ( earlier post ) and motor vehicles are important sources of BC in the environment. Credit: ACS, Wang et al. Click to enlarge.

Nanostellar was founded in California in 2004 by scientists from Stanford University and NASA Ames Research Center. Many pollution control and renewable-energy applications require precious metals that are limited—there isn’t enough platinum to supply the millions and millions of automobiles driven in the world.

The study by Nadine Unger, Drew Shindell and James Wang will appear in an upcoming issue of the journal Atmospheric Environment. This model has been used previously to understand the role of short-lived air pollutants in climate change for past, present and future atmospheres. Unger et al. Click to enlarge. Unger et al.
