There are several parts to the answer.
First, there are technologies available to significantly reduce emissions. We are familiar with renewable energy. For example, according to our scenarios, wind energy is projected to account 18% of the electricity produced in Canada in 2020. We have many possibilities in energy efficiency, and also in carbon capture. We therefore don't need to come up with new technologies; we already have solutions.
Second, yes, our scenarios call for carbon pricing. That would create a high price for emissions. It would also generate revenue that could be recycled into the economy to be reinvested in solutions and deal with problems that might arise, such as competitiveness problems in some specific sectors.
That is the answer I gave earlier; after all, the Canadian economy is primarily a service-based economy, and large parts of the manufacturing sector are not particularly big sources of greenhouse gases.
