Mr. Speaker, as I have said on numerous occasions already, it is not possible to solve the problem of greenhouse gas emissions in the past. It can always be done in the future. There are various ways of measuring greenhouse gas reduction targets. The Americans have proposed targets and outcomes very close to our own. We are in discussions with the U.S. government in order to ensure effective regulations for the North American continent.
