We're spending right now $1.5 billion converting, in our oil sands mining sites, from using coke as a fuel source to provide heat and steam for our operations to natural gas. That's fuel switching, and it has a significant reduction in carbon emissions.
In our in situ operations, the operations that drill wells and produce from reservoirs, we're spending several hundred million dollars right now on pilot work to look at introducing solvents as opposed to steam, again to dramatically reduce the carbon content. I commented on it.
In St. Clair, we have a renewable-fuels ethanol plant, the country's largest. We're looking at what we can do to further expand or improve that operation.
I think it's across the board. To make the base business better and to grow new renewables businesses are where we're focused.
