Canada may make minor adjustments to its targets for cutting greenhouse gas emissions before climate talks in Copenhagen next month, Reuters quoted Canadian Prime Minister Stephen Harper as saying today. Harper told reporters on the sidelines of a Commonwealth summit in Trinidad and Tobago his country believed it was essential to keep Canadian targets in line with those of its neighbor, the United States. "I notice the United States has come out with a target of 17 percent below 2005 levels from now to 2020 -- that"s virtually identical to Canada"s own target, so we may make some minor adjustments, but that will essentially be our target," he said.
