Yes.
I think in terms of regulatory clarity on the environmental side, certainly from a hydrocarbon business viewpoint, understanding where we're going to go on climate change and what the expectations are.... It would take a very brave soul to build a brand new refinery today. There's lots of investment in incrementally expanding the refineries we have. But a grassroots refinery is $3 billion to $4 billion. We don't know where we're going in terms of climate change. Will it have an effect on demand? There are things that can drive the demand down, in which case our refining capacity would be more than adequate.
Those types of issues need to be clearer, so that people have an idea of where they can go, so that before they put those kinds of dollars into the ground, they know there's a good chance of getting a return.
