Although China and India remain the world’s largest consumers of coal, a new University of Maryland-led study found that China’s sulfur dioxide emissions fell by 75% since 2007, while India’s emissions increased by 50%. The open access study is published in the journal Scientific Reports. Click to enlarge. —Can Li.

That the reduction has not materialized—and that global emissions have instead risen—is a puzzle, and may have implications for the Montreal Protocol, the international treaty that was designed to protect the stratospheric ozone layer. However, it looks like there is still work to do.

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.

The Bakken Formation, a shale oil and gas field in North Dakota and Montana, is emitting roughly 2% (about 250,000 tons per year) of the globe’s ethane, according to new study led by researchers at the University of Michigan. Hydrocarbons react with NO x and sunlight to produce ozone. Ground-level ozone leads to poor air quality.
