Because of planes’ emissions, large airports are important sources of local air pollution, including fine particulate matter, which can increase people’s risk of heart disease and asthma. Now a study has found that particulate matter emissions from a plane’s engine can fall by almost 40% when researchers blend jet fuel with alternative fuels (Environ. Sci. Technol., DOI: 10.1021/es201902e).

The study tested two types of alternative fuels: biofuels made from animal fat or vegetable . . .
