COP28 Episode Five
Urbanisation, Built Environment and Transport
At the halfway point of COP28, discussions on urbanisation, the built environment, and transport underscore the pivotal role cities and technological advancements play in combating climate change. Sally Capp, the Mayor of Melbourne, Australia, highlights how cities, being major emitters, must lead in climate action. Melbourne exemplifies this by achieving a 76% reduction in emissions.
Rajal Upadhyaya, CEO of ROAM, explores public transit innovations, particularly in developing regions like India and Kenya. The introduction of electric motorcycles and buses not only curbs emissions but also enhances public health and saves consumers money, demonstrating a holistic approach to sustainable transit.
Aviation's leap towards sustainability is illustrated by Rob Miller, Professor at University of Cambridge, who recounts pioneering hydrogen-powered flights and engines, marking significant strides in reducing aviation's carbon footprint. This sentiment is echoed by Alan Newby, Director of Aerospace Technology and Future Programmes at Rolls-Royce. He advocates for a comprehensive plan to achieve net-zero aviation by 2050, integrating efforts across all sectors. There are great challenges in scaling sustainable aviation fuel production, as LanzaTech CEO Jennifer Holmgren points out, yet optimism for a cleaner aviation future remains.
Meanwhile, Dr. Meganne Christian, Astronaut and Exploration Commercialisation Lead at UK Space Agency, delves into the critical role of space infrastructure in climate monitoring, emphasising that over half of climate data relies on satellite technology. Aarti Holla-Maini, Director of UN Office for Outer Space Affairs, adds that the sustainable management of space resources and debris is crucial, highlighting the UN's role as a neutral convener in addressing these global challenges.
COP28 illuminates the diverse avenues through which urbanisation and technological advancements can drive meaningful climate action, necessitating coordinated global efforts to ensure a sustainable future.
