At the Office of the Auditor General, including in my role as commissioner, we work closely with our counterparts around the world through the international network known as INTOSAI, and in particular the Working Group on Environmental Auditing.
You've hit on an important point there, which is the potential for an uneven playing field. If one jurisdiction sticks its neck out and does something and the others don't follow, it could be put at a competitive disadvantage and so on.
It's a difficult issue with climate change, because you're never going to get a 100% consensus among nearly 200 countries on every measure and every definition and so on. There's always going to be some unevenness. There are going to be all sorts of externalities and market failures, as is the case right now.
To the best extent, if we can at least collaborate with our G7 and G20 colleagues in looking at this in a coordinated way, which, as you mentioned, includes peer reviews with other nations, then we'll have a better chance of having the entire herd go in the same direction, rather than just one of us going ahead of the pack or behind the pack.
