Now, there is something that I should mention here, because this obviously has an intersection with climate change and the commitments that we've made. Now, international aviation and international shipping, neither of those are covered by the Paris Agreement, right? So the only place to handle emissions from international shipping and international aviation is through these separate agreements. When it comes to international aviation, of course, it's the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) agreement. When it comes to shipping, it's MARPOL. Now, some countries are moving to integrate their international aviation and shipping emissions into their national greenhouse gas inventories. The draft advice of the Climate Change Commission that came out in February of this year—when you look at the modelling that they've produced, they've actually left some buffer zone on there. I guess the probability that they're calculating was that we will probably follow that trend and start to incorporate them, particularly given where we are located in the world and the fact that we are a trading nation, that we're highly dependent on tourism, and that both aviation and shipping are absolutely central functions of our economy.
