Volvo Trucks introduced two gas-powered, heavy-duty trucks that offer fuel efficiency and performance on par with that of diesel-fueled trucks, and comply with Euro 6 emissions regulations.

The idea was nothing short of revolutionary: Convert the nation’s millions of trucks, buses and other commercial vehicles to run on natural gas instead of gasoline and diesel.

The tightening of emissions limits for deep-water ships has some of North America’s busiest ports chasing a new opportunity.

Vehicle tailpipe and crankcase emissions are the highest sources of methane emissions from heavy-duty natural gas-fueled vehicles and the fueling stations that serve them, according to a study by West Virginia University scientists.

To assist the government of Ontario in the design of a heavy-duty truck natural-gas program, the Ontario Trucking Association said it issued “Natural Gas as an Alternative Fuel for Canadian Truck Fleets: A Roadmap Toward Implementation.”

Alternative fuel distributor American Natural Gas added 18 compressed natural gas fueling stations in eight states to its network through the separate acquisitions of Constellation CNG and Questar Fueling Co.
