Study: IMO low-sulfur fuel standards will decrease childhood asthma cases, premature deaths; climate tradeoffs

Green Car Congress

Marine shipping fuels will get cleaner in 2020 when a regulation by the International Maritime Organization (IMO) requires a decrease in the allowable amount of sulfur in fuel oil from 3.5% Cleaner marine fuels will reduce ship-related premature mortality and morbidity by 34 and 54%, respectively, representing a ~?2.6%

Study finds large-scale ramp-up in biofuel crops could result in warming in some tropical regions, cooling in temperate and polar regions

Green Car Congress

Global land-use changes caused by a major ramp-up in biofuel crops—enough to meet about 10% of the world’s energy needs—could make some regions warmer, according to a new integrated modeling study by researchers from MIT and the Marine Biological Laboratory, Woods Hole. —Willow Hallgren, lead author.

EPA releases national assessment of strategies to reduce air pollution at ports

Green Car Congress

A new report from the US Environmental Protection Agency (EPA) finds that air pollution at US ports can be reduced significantly at all port types and sizes through a variety of strategies and cleaner technologies. In 2030, adding plug-in hybrid electric vehicles to these fleets could yield even more NO x and PM 2.5
