In addition to CO 2 , other compounds such as ozone (O 3 ) precursors (nitrogen oxides (NO x =NO+NO 2 ), carbon monoxide (CO), and volatile organic compounds (VOCs)) and aerosols such as black carbon (BC) and organic carbon (OC) are emitted by ships. Of that, international shipping accounts for 83% (870 TgCO 2 yr ?1

Jacobson at Stanford University. Results of the study suggest that soot is second only to carbon dioxide in contributing to global warming. Jacobson found that the combination of the two types of soot is the second-leading cause of global warming after carbon dioxide. He also found that soot emissions kill more than 1.5

Traffic contributes more to NO x emissions in Europe than previously thought, according to a new study by a team at the University of Innsbruck. We continuously measure the concentration of carbon dioxide, nitrogen oxide and volatile organic compounds at our urban observatory in Innsbruck. We record 36,000 data points per hour.

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

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.

Biofuels based on low input cultivation of non-food crops offers promise in developing countries as a source of energy, in part because energy use is often very low at present. No study in the review presents results in terms of biodiversity. However very few studies include water use impacts. Menichetti and Otto. Ravindranath et al.

Isoprene, a five-carbon diene formed naturally in plants and animals and a precursor of ozone, contributes more than 40% of these emissions. Global simulations show an enormous flux—nearly 100 teragrams of carbon per year—of these epoxides to the atmosphere. Paul Wennberg, Caltech, project leader. Dr Kleindienst.
