Regine Guenther, director of the World Wildlife Fund Climate Change Program in Germany, told reporters that G8 leaders should commit to reducing emissions in their countries by 40 percent by 2020 and 80 percent by 2050. "If we don't achieve that, the world's climate will change in ways that we can't even imagine today," Guenther said.Respondents were given two options: Did they support a more cautious policy approach "so that we don't drive up the cost of fuel and the cost of living even further?" Or do they believe that "the rising price of fossil fuels is a reason we must move even more aggressively to reduce our dependence on fossil fuels."Meanwhile, in the U.K., Prime Minister Gordon Brown plans to increase renewable energy use in Britain tenfold by 2020. Brown's vision for a "green revolution" is heavily reliant on wind power, with plans for 7,000 new turbines 4,000 onshore and 3,000 offshore. The North Sea could turn "into the equivalent tive value chain." Some of his work includes the use of wheat-straw, hemp and flax to create bio-based products that can be readily incorporated into the current automotive plastics industry.
