Our Summit has offered us the key opportunity that we have all been waiting for, traveling from our dear cities, and I would like to thank the C40 organization and all the mayors that have made our joint involvement possible. Our involvement is one for our citizens and we must always speak in their voice. That is what I refer to as loyalty to our land. Our loyalty to the real world that we face day to day. It is in this real world that our professionalism is rooted. It is a professionalism not of experts, but of pragmatics. It also stems from the trust and friendship existing between us mayors. I would like to thank you, dear friends, for your conscious commitment as I believe that, as mayors, we like to harbor illusions. But also for your relentless efforts, which clearly define us all : we never give up, and that should never change!
