Not to pick on California again, but California, as Mr. Smith has mentioned, has been a real pioneer since the nineties, and Norway as well. They've taken a different approach where they've included a lot of tax credits and subsidies. That approach works in that environment and that culture. I think in California it's a little more analogous to Canada. What they've done is that they've looked at supply and demand and really understood that we are transitioning from a 100 years of fuelling, manufacturing and using vehicles, and that we need a comprehensive suite of policies. In addition to what Mr. Smith mentioned, they are leading on measurement in terms of being the first state to adopt the guidelines set by the federal department in the U.S.
The other thing I'll point out is that the utilities in California have been actively engaged, and they've worked with the regulator to make critical investments to help leverage private capital to support infrastructure deployment across the state. The last thing I'll say is that we always talk about California, but I will acknowledge that there are about 45 states in the U.S. that have some form, either through their utility or through their state, of either incentive or regulation. Mr. Smith mentioned supply-side policies. As a mandate on the consumer vehicle side, there is also the clean truck rule, which is a similar supply-side mechanism for trucks, and that is aiming towards having 100% zero-emission vehicles in 2045. I will note that there are about 15 other states that have signed on to both of those policies. It's not just California, but they are the leader.
