I'm thinking of genetic engineering, for example. A lot of work is being done in that field in Canada. We innovate extensively for ourselves, but we should also do it for other countries. Once again, in the context of today's discussion, we have to think about Ukraine. International trade can definitely create a larger carbon footprint. So we have to pay attention to that aspect of the situation.
Twenty-seven countries around the world have a carbon tax. However, we don't really know if that approach is effective in reducing greenhouse gas emissions. That's why we have to be very cautious and refrain from imposing our aspirations as a rich country, which you have to admit we are, on countries that have suffered greatly.
