I'm sorry to interrupt, but I have only six minutes of time. Thank you for helping me home in on this.
Specifically related to the coal phase-out in 2030, if we have no coal in this country, we have no fly ash production. If we have no fly ash production, then cement production becomes cost-prohibitive, because we'll have to import fly ash from the United States. Have there been any impact studies on the cost of increases in infrastructure specifically with regard to the phase-out of coal and the loss of fly ash production?
