Perhaps I could start, Mr. Chair.
Without getting into all the details that are provided in the “2030 Emissions Reduction Plan”, I think the key point is that it represents the current plan and it does indeed take some steps to address at least some of the recommendations made by the commissioner. I would address two, and maybe I can turn to my colleagues from other departments to talk about the others.
In terms of the modelling, the modelling projections in the “2030 Emissions Reduction Plan” represent a much more detailed set of inputs and rely less on some background assumptions, as was the case in the earlier plan, including the assumptions that we needed to make about the likely impact of the forthcoming hydrogen strategy, for example. The annex is available for everybody to read. If the committee is interested, we'd be happy to come to talk about the modelling annex and the assumptions in it at a later date.
On carbon pricing, we agree with the findings of the review of the audit and the four recommendations, and indeed, are committed to developing and publishing a written plan to respond to those four recommendations. It's our view that we've already started to respond to those recommendations primarily through the new benchmark criteria. The basic approach to carbon pricing has been to develop criteria for provinces for all pricing systems, federal, provincial and territorial. Inherent in the development of those criteria is the inevitability that there will be differences among systems. If there was a desire to have one system, then we would only have one system, but we've acknowledged that provinces were early movers and we've acknowledged that provinces need to have the ability to take action in ways that address their own circumstances.
The bottom line is that these criteria are significantly tighter, provide longer-term certainty and should go a long way to addressing some of the discrepancies that the commissioner pointed to. In addition, we published input on our advice to all jurisdictions about revenue use so that revenue return can be used to, among other things, offset some of the potential impacts on vulnerable communities.
