International negotiations have recently focussed attention on a multigas approach to meet greenhouse gas emission targets. This approach increases the control options and can lower the national costs of meeting international agreements, as illustrated here by the example of CHreductions for the United States. Based on the latest abatement costs, we estimate that for short-term targets, CHcan offset COreductions and reduce U.S. costs by more than 25% relative to strategies involving COalone.
