In the race for the White House, both Barack Obama and Mitt Romney have talked about sustainable development.
Yet the Green Party ticket, whose stance on the issue outpaces those of both the Republican and Democratic parties, is virtually unknown by the vast majority of US voters.
Romney, who has campaigned while standing in front of a coal mine in Ohio and enjoys support from the billionaire Koch brothers who made their fortune in oil, gas and chemicals, is the bane of many environmentalists.
Meanwhile, Obama has been criticised for not cracking down on hydraulic fracturing, or fracking, a technique that uses chemicals and water to blast through underground shale formations.
Obama, who has stated that “climate change is the one of the biggest issues of this generation” and promised to “begin to slow the rise of the oceans and heal the planet”, has nevertheless given the green light for offshore oil leases in the environmentally sensitive Arctic Ocean, leaving the 66 per cent of US citizens who favour tax breaks to curb greenhouse gas emissions without a candidate.
