Thank you for that.
The next question I have is.... Transportation is almost a quarter of our emissions. It's the second-biggest source right now. Collectively, with oil and gas, that's more than half of our country's emissions. I was hoping you could speak to the importance of having a long-term steadily rising price on pollution as a mechanism to ensure that you have the investment being made into some of these renewable and cleaner alternatives, such as biodiesel, to reduce emissions from the highest sources in our country.
