Addressing an Atlantic Council forum on October 3, former U.S. Ambassador to the European Union C. Boyden Gray commented that a free trade agreement between America and the union should be based on cooperation to align transportation fuel and emissions standards. He also said opening up the transportation sector to natural gas should be a priority. At the same event, American Council on Renewable Energy Vice President of Corporate Relations said agreements might be more easily achieved should they focus on transportation rather than electricity generation. He also said emissions can be cut by a variety of means, ranging from biofuels to electric vehicles.
