That's a very interesting question because we increasingly see greenwashing around us. I recently noticed it at a truckers' festival, where all those GHG emissions were offset and people claimed to be eco-friendly. You can be glad they offset their GHG emissions, but, in the end, it was still a major polluting event that shouldn't have been considered eco-friendly or sustainable.
You can introduce very specific measures to restrict both the cases in which people can use these credits and the kinds of allegations that can be made when using the credits. For example, minimum conditions for distributing or using credits can be defined. You can state all the minimum criteria that must be met to be certain that credits are of high quality. You can also restrict the circumstances in which they may be used. For example, should we allow an airline to offer carbon-neutral flights? Perhaps we shouldn't allow that. Perhaps we should permit the use of credits as a good measure by ensuring that we clearly explain that credits don't make flights carbon neutral, that aviation is still a polluting industry and that a transition is necessary. The use of carbon credits should be clearly delineated.
What California has done is very interesting. It has passed legislation requiring all businesses that distribute or use carbon credits or offsets to disclose information on their quality. This then provides the government with information on criteria and quality, and they determine the purposes for which those credits can be used. Canada should do the same thing by amending the Competition Act, for example. Amendments have recently been made to that act and others should follow. We should also make regulations or pass a separate act, as California has done, to determine clearly how those credits are to be used.
I agree that significant risks are involved in the use of carbon credits and offsets. Everyone around this table seems to feel that credits can present quite significant greenwashing risks. We should clearly determine how they are to be used.
