We're investing $300 million a year on R and D. By converging a number of technologies and investing another $550 million in this commercial-sized plant in Quebec on AP50, we're looking at 20% efficiency gains, elimination of PAHs and fluoride emissions, and a reduction of CO2.
Now, we want that in five years. If we invested less, we'd probably have to wait 10 years or 12 years for it. So we have to move faster, and we need that regulatory certainty to be able to do that. That's where you get the gains.
