Study suggests high-mileage light-duty fleets contribute higher emissions and emissions share than expected

Green Car Congress

A study by researchers from the University of Denver and the University of Puget Sound indicates that high-mileage light-duty fleets contribute higher emissions and emissions share than expected based on their actual numbers in the fleet. Most emission inventory calculations use a computer model to estimate the fleet’s emissions.

Honda Transmission contracts with Juhl Wind for two utility-scale wind turbines at Ohio plant; up to 10% of electricity for operations

Green Car Congress

Last June, the Washington Township (Logan County, Ohio) Board of Zoning Appeals approved a variance to the height limitation for the wind turbines. This includes a 30% reduction in CO 2 emissions from Honda products, and significant CO 2 reductions from the company’s plants and other operations, compared with year 2000 levels.
