Here's a plan, off the top of my head: capture the CO2 in the exhaust, use some of the power from the plant to freeze it into dry ice. Feed the heat back into the power plant somehow so it's not wasted. Take the dry ice and ship it to the poles, and bury it. If there's enough, and it's packed under dense snow and water ice, it won't sublimate as quickly and will help keep the snow and water ice frozen. $6.7M is probably not enough to even attempt this, even if it could actually make a difference. Which it probably couldn't.
