BONN, Germany, June 3 (Reuters) - The United States will tell a July meeting of the Group of Eight rich nations that it cannot meet big cuts in emissions of planet-warming gases by 2020, its chief climate negotiator Harlan Watson said. "It's frankly not do-able for us," he told Reuters on Tuesday, referring to a goal for rich countries to curb greenhouse gases by 25-40 percent by 2020 compared to 1990 levels.
