Thank you very much for the question.
I think there is an immense opportunity to be able to expand. As I say, in California, we're taking this plant from 3,000 barrels a day when we bought it, up to 25,000 barrels a day. We're looking to make additional investments. We can expand our plant in Hamilton, Ontario. We can do that because we have to have a way to have transparent trading credits that can establish this market here. Right now, the California market has a very strong and transparent trading economy on carbon reductions. If we could establish that in Canada through the clean fuel regulation, that is going to attract investment and we will be able to scale up and make significant advancements.
That's not to mention we're constantly looking on every upgrade that we do to any plant. We assess that on a carbon basis as well. What is the most efficient way to do that? By generating more carbon reductions with every capital investment we make and every gallon we produce, we can achieve that faster.
Over the last 15 years that we've been producing, we have made investments that have made every gallon more valuable from a carbon reduction perspective, including upgrading the by-products to replace petrochemicals and things like that, which allowed us to get past a net-zero basis.
