 Cities have well over half the world's population and three quarters of the world's economic activity. How that population lives will drive many of its sustainability issues globally. It's really critical to focus on the role of cities to reduce emissions. Making cities resilient to the climate change that is underway and that is already exacerbating dangers. Really important to plan well for the future and to do that planning well, you need proper climate projections and you know what you're dealing with. Further research on the city's perspective within the larger climate picture is absolutely essential. The real focus on research has to be working together with scientists, policymakers, innovators to find means for driving transformation. People need to be empowered by the knowledge that we can do things to prevent the worst consequences. So we need much more emphasis on what's due and then I think people will demand action. I believe cities is the place for the positive change because cities work closely with the stakeholders, with the people on the ground. Of course local governments are key leaders to reach out to the citizens so they have enormous potential to move ourselves into the next era of sustainable development. The choices we as an individual have is constrained by the infrastructure we live with. It is important policymakers, elementary, low-carbon infrastructure for the future. We need to get practical. We need to show the advantages to the citizens of using energy in a different manner. We need to change the way that we value things. A model of collaboration between cities is one where you can see an overall plan for the world emerging to solve big problems like climate change. These sorts of conferences allow us to build those networks of people, network of knowledge, network of institutions to build a world resilient and with clean energy. The core of this is clear, both moving to renewable energy and to electrification of transport industry. Heating in buildings is at the essence of decarbonisation. The measures that we need to take to tackle climate change will make a much better world, a much happier world, a much stronger economy, a much more sustained development of human welfare. We'll have better lives if we make these investments. The future city can be clean, green, fair, inclusive, healthful and should be.
