I will first address that aspect. I have just completed a study in August which shows that, even if we think this kind of measure could reduce emissions in other countries, the net result would be an increase in Canada's production costs, or in any country which adopts these measures.
Let's look at the case of steel import from China. Chinese steel is used by our industries to produce goods. If we increase the tariffs on Chinese steel imports, it would simply increase our production costs and generally be bad for us. That is the first repercussion I envisage.
The second aspect concerns our industries which export toward Europe. They will basically be at the receiving end of measures taken by the Europeans. That's clear. If the Europeans apply import duties on countries which do not reduce their greenhouse gases, there is no doubt this will affect us, which is why we must also take measures similar to those of other countries.
In my opinion, applying these tariffs represents a threat for countries who have not yet taken measures to bring down their greenhouse gas emissions, it would be a means of persuading them to do so. But it's actually working. China has just announced that it will begin to take measures to reduce its greenhouse gases, if only slightly, by bringing down the intensity of its emissions. However, implementing these measures is bad for the country which does so in the first place, and it is also bad for the country which is targeted by this type of policy.
Generally speaking then, I would say that if one country imposes this type of tariffs, it would mean that everyone else will be forced to adopt a similar policy, including, of course, Canada—
