HEI ACES study of lifetime animal exposure to New Technology Diesel Engine exhaust finds no lung cancer

Green Car Congress

exhaust from heavy-duty diesel engines meeting EPA 2007 and later emissions requirements—has found no evidence of carcinogenic lung tumors. The study exposed laboratory rats 80 hours a week, for up to 30 months, to emissions from a heavy-duty diesel engine meeting 2007 US EPA standards using new filters and other control technology.

SCOPE Biofuels Project Releases Assessment on Environmental Effects of Biofuel Technologies

Green Car Congress

Low-input cultivation of perennial plants, e.g. from short-rotation forestry and grasslands, may be an effective source of cellulosic biomass and provide environmental benefits (reduced pollution and lower greenhouse gas emissions). Very few studies include a data quality review according to the requirements of the ISO standards for LCA.

First results from HEI/ACES murine study find few biologic effects from exposure to exhaust from new technology diesel engines

Green Car Congress

The study—a component of the Advanced Collaborative Engine Study (ACES)—is exposing rats and mice for 16 hours a day to emissions from a heavy duty diesel engine meeting 2007 US EPA standards that reduce emissions of fine particles and other pollutants by more than 90% from levels emitted by older engines.
