It's a good question. It's equivalent to what we're discussing when it comes to carbon as well. The reality is that there are some sectors that can reduce substantially easier than others, whereas some have a substantially more difficult time. Setting a federal target will basically force companies to kind of hit that target.
There are usually some sort of sectoral differences. I guess my personal preference would probably be to move to some sort of sectoral target that the federal government could potentially implement, taking into consideration the type of industry that you're dealing with, who can hit a target easier than others.
What you really don't want is to set a target that's unrealistic, that nobody's ever going to be able to hit. It will spur innovation, but it also sometimes spurs companies leaving one jurisdiction to go manufacture in another. You always have to be careful about capital—capital risk, capital flight.
