I would just echo the point about the further reductions that can happen in the transportation sector. As I mentioned, the way in which we regulate in that space is to look at model years for the vehicles you purchase, making them more and more efficient. We don't regulate the efficiency, but that's what the net outcome of the regulations is, in terms of vehicles consuming less fuel and emitting less greenhouse gases.
Then we see the uptake of new technologiesāthings like zero-emissions vehicles and the role they play there. That will continue to play an important role as we move forward.
Finally, I would mention the importance of a clean fuel standard, which helps to drive down the carbon intensity based on the life cycle. I know that's a complicated statement, but essentially what that means is that, from using or extracting the elements that form the fuel to the way in which you combust it, if you can make that more efficient, it drives down the carbon intensity and results in fewer greenhouse gases.
The design of that will be an important element, and it will influence the emissions from all sectors of the economy because it's related to fuels that you use in your homes, in industry, in your cars and in business. It will be an important tool moving forward. It will be a way to help move forward with continued reductions in that 2030 time frame as well.
