That's a perfect example of why long-term price signalling is really important. One of the things I didn't get a chance to say was that in jurisdictions like the U.K., they've agreed to make climate policy a non-partisan issue and to use a certain method to reduce emissions and get on with it, so that it's not flip-flopping with a strong policy that is then removed. We want to build bridges between parties so that we can have long-term certainty in a carbon price.
