 It's a great day. The opening day. We have a session on energy efficiency. It is really a dream. Normally you would think, as the Americans would say, it's a no-brainer, but we have not seen enough police attention on energy efficiency. So as such today is a very good day. There's a very strong, unstoppable growth of clean energy. Review buses are really star. For us there are five conditions to consider to be successful. These pledges are made, but commitments and pledges are something, doing them is something else. So we at the IEA as the custodian of those numbers, we will track the progress of countries, what they said at COP28 and what they are doing.
