We did a report on this in November 2022, if memory serves; I have several documents in front of me.
We did an analysis of that and realized, as most observers have, that the fuel tax or the greenhouse gas emissions tax isn't enough to meet or exceed the Paris Agreement targets, as the government committed to in the 2021 budget.
Other measures, which the government has announced, are needed to achieve the targets the government has set for itself. It's often said that the carbon tax will make it possible to achieve one‑third of the greenhouse gas reduction targets. From memory, those are the conclusions we reached.
