Gas stations venting ten times more gas vapor than once believed

Exposure to the chemicals contained in gasoline vapor poses serious risk to human health. Technologies have been implemented to reduce the amount of gasoline vapor released along the supply chain and during the routine fueling of vehicles. The evaporative loss during storage has been largely under-addressed, due to the perception that the quantity lost is fairly small. New research reveals that vent-pipe-emissions from underground storage tanks may be an order of magnitude higher than previously believed, and that people in proximity to these vents may experience an elevated exposure risk.

Many variables in play as deadline for maritime fuel sulfur reduction approaches

Maritime shipping remains the most efficient way to transport goods, considering its weight to fuel-economy ratio. Still, an average container ship running on typical high-sulfur fuel emits nearly the same amount of sulfur oxides (SOx) as 10 million diesel passenger cars. By some counts shipping contributes over 5 percent of global sulfur emissions. Beginning in January 2020, the United Nations International Maritime Organization (IMO) is requiring the maritime industry to reduce the sulfur content of its fuels from 3.5 percent to 0.5 percent, in an effort to reduce SOx, particulates, and other pollution.
