The ban on ozone destroying chemicals was a global ban, so a level playing field. Very different than the actions on Carbon. But the author ignores the fact that aside from our resource industries, where significant innovation is well underway most Canadian companies only tool to reduce carbon is to reduce energy use. Canada does not design the equipment that produces Carbon such as cars, industrial engines, power generators and so on. All that Canadian companies can do is to buy the best equipment that is produced by the countries that make such equipme3nt. Those countries will be doing the innovation, not Canada.
