This is going to be a barrier to taking strong action on climate change. What provisions like the ISDS provisions put in place is an assumption the status quo is working.

If we take strong action, which we need to and we're committed to do, those are exactly the types of measures that can be challenged under the ISDS provisions, and that's going to be a problem.
