To briefly respond, there are at least 15 proven technical ways to reduce greenhouse gas emissions. Each country does not have to use all of these methods. If in Canada, from a technological point of view or because of our environment, it is better to focus on certain sectors, then we don't need all of the other methods. If Canada adopted carbon capture and storage as a way to mitigate the Athabasca oil sands refinery emissions, and if we made better use of existing types of energy, if we slowly but surely got rid of fossil fuels, we could reach our objectives, such as those contained in the bill, even if we did not use carbon sinks—our forests—or other types of sinks.
