Steve Williams has made it easy for me. He's been very clear. He believes that a broad-based carbon pricing mechanism is a necessary mechanism and that climate change is a challenge we need to address right across the value chain. We need to do our fair share. He's been very clear about that, but we need to ensure that we're addressing the challenge right across. As we know, 80% of emissions come from the tailpipe, so if all of the climate change focus is on the upstream, then we're not actually addressing the challenge to the best of our abilities.
