U.S. mayors join call for ban on oilsands-based gasoline

U.S. mayors are adding their voices to those raising concerns about energy produced from Alberta's vast oilsands.

The U.S. Conference of Mayors, meeting in Miami this week, has approved a resolution calling on its members to ban the use of energy from unconventional sources because of its impact on the environment.

"We don't want to spend taxpayer dollars on fuels that make global warming worse," said Eugene, Ore., Mayor Kitty Piercy, who submitted the resolution.

"Tarsands oil emits up to three times the greenhouse gases in the production process per barrel as convention oil production. Our cities are asking for environmentally sustainable energy and not fuels from dirty sources such as tarsands."

The mayors said importing oilsands fuel slows the transition in the United States to cleaner energy sources.

"Global warming is one of the most critical issues facing our cities," said Mayor Frank Cownie of Des Moines, Iowa.

"This resolution shows our willingness to take action to move forward, not backwards, which is where fuels such as tarsands oil will take us."

Resolution 'misguided': Alberta energy minister

Alberta Energy Minister Mel Knight was quick to react to the mayors' resolution, calling it "misguided."

The province has strong environmental standards in place, Knight said, along with its own climate-change program.

"The fact of the matter is that we lead North America in almost any of these types of production-related environmental standards and we need to have our trading partners and consumers understand that."

The provincial government's plan to limit greenhouse gas emissions focuses on the development of carbon capture technology to storecarbon dioxideunderground so it will not escape into the atmosphere. But the plan, announced earlier this year, does not require industries to reduce their emissionsuntil 2020.

Alberta Liberal Leader Kevin Taft also waded into the debate Monday, saying the province can't afford to ignore the warning from its southern neighbours.

"This is an important group and when you go through the details, this is another step in the road towards the U.S. government actually singling out the tarsands production and taking steps not to buy it. Alberta's got to pay attention to this, big time."

Alberta has seen growing protests over its oilsands development.

During a visit to Washington earlier this year, Alberta Premier Ed Stelmach faced protesters demanding a ban on what they called "dirty oil" from the province's oilsands.

U.S. legislators have already adopted laws that limit the use of fuel made from unconventional sources because of its high greenhouse gas emissions.

But U.S. officials say the regulation will not apply to oilsands production.
