Minnesota Introduces World's First Carbon Tariff 303

Posted by timothy from the hey-cut-that-crap-out dept.
hollywoodb writes "The first carbon tax to reduce the greenhouse gases from imports comes not between two nations, but between two states. Minnesota has passed a measure to stop carbon at its border with North Dakota. To encourage the switch to clean, renewable energy, Minnesota plans to add a carbon fee of between $4 and $34 per ton of carbon dioxide emissions to the cost of coal-fired electricity, to begin in 2012 ... Minnesota has been generally pushing for cleaner power within its borders, but the utility companies that operate in MN have, over the past decades, sited a lot of coal power plants on the relatively cheap and open land of North Dakota, which is preparing a legal battle against Minnesota over the tariff."
