The Ethics and Justice of Low-carbon Transitions
Abstract: What co-benefits does low-carbon energy or transport bring? What are the types of injustices associated with low-carbon transitions? Relatedly, in what ways do low-carbon transitions worsen social risks or vulnerabilities? Lastly, what policies might be deployed to make these transitions more just? Drawn from a rich set of original mixed methods data—across expert interviews, focus groups, and public internet forums—we examine the multidimensional, qualitative co-benefits to nuclear power in France, solar photovoltaics in Germany, electric vehicles in Norway, and smart meters in Great Britain. We catalogue 128 co-benefits to these four European low-carbon transitions, 30 for nuclear power, 30 for solar photovoltaic panels, 26 for electric vehicles and 42 for smart meters. Tellingly, 37 of these collective benefits are identified as economic and 14 environmental, but the remaining ones illustrate a broader spectrum of technical benefits (31 in total), social benefits (30 in total) and political benefits (16 in total). Furthermore, the presentation documents 120 distinct energy injustices across these four transitions. It then explores two exceedingly vulnerable groups to European low-carbon transitions, those recycling electronic waste flows in Ghana, and those mining for cobalt in the Democratic Republic of the Congo. The presentation aims to show how when low-carbon transitions unfold, deeper injustices related to equity, distribution, and fairness invariably arise.

Indoor Air Quality Assessments in School Classrooms
Abstract: Since the beginning of the COVID-19 outbreak, cities across the globe have faced national lockdowns. In July 20202, the ‘airborne’ route of COVID-19 transmission was recognised for the first time in indoor public places with high occupancy and low ventilation. It highlighted the need of understanding the ventilation and aerosol concentrations to devise mitigation measures for the COVID-19 transmission. Funded by the Engineering and Physical Research Council, COTRACE (COvid-19 Transmission Risk Assessment Case studies - education Establishments) project aims “to quantify the risk of airborne COVID-19 transmission in schools and evaluate the effectiveness of mitigation measures, by developing techniques to assess the absolute risk of infection in a given indoor space, using field studies in primary and secondary schools, complemented by laboratory experiments and CFD to elucidate the flow patterns responsible for airborne transport”. This presentation will provide an overview of the intensive monitoring campaigns carried out over the last year at multiple classrooms simultaneously in nearly a dozen schools. The monitoring locations included classrooms, halls and other areas where the occupancy is usually highest and ventilation is limited, with a view to understand the ventilation, indoor air quality and the risk of airborne transmission.

Development of Decarbonizing Supply Chains for Circular Economy towards Carbon Neutrality
Abstract: The development of decarbonizing supply chains can drive the concept and atmosphere of green consumption and eco-living in society and industry, thereby promoting and implementing the green technology into sustainable industry for circular economy. The decarbonizing supply chains can also be applied to the production and manufacturing of green products to reduce the environmental impact of related processes and upstream and downstream chains and to increase the efficiency and added value, as well as to improve product quality and thus bring opportunities for the clean and green development of society as a whole. By developing more affordable and better promising green technologies, they may significantly reduce the cost of reducing CO2 emissions changing the level of upgrading of industries, shifting production from low to high value-added industries, which in turn also stimulates economic growth towards carbon neutrality. In general, the development of new green technologies often requires systemic innovation, and the higher level of innovation investment. In the future, through the growing awareness and development of green technologies around the world, the emergence of green technologies may help companies to reduce the unavoidable costs of reducing carbon dioxide emissions.

Gearless Electric Motor Drives for Electric and Hybrid Vehicles
Abstract: With changing consumer habits, government regulations and sustainability requirements, research on electromobility applications, in particular electric vehicles, has drawn much attention. It is anticipated that by 2040, annual sale of electric and hybrid vehicles is projected to outsell gasoline and diesel vehicles, with estimated sale of 48 million units per year. As the key component of the electric and hybrid vehicle systems, development of electric motor drive has become a hot research topic. In the conventional gear-drive system in electric vehicles, the propulsion motor is connected to the wheels through a series of mechanical transmission components. The mechanical transmission inevitably results in reduced efficiency, boosted weight, and increased maintenance cost. An alternative solution is to employ direct-drive system, or also known as gearless system to eliminate the mechanical transmission components. In such case, more space is spared for battery and passenger accommodation, while better control flexibility can be realized with independent wheel control. In the past century, the energy storage technique has been developed rapidly, and high-power density batteries have been employed for automobile applications. Various gearless electric motor drives are also investigated, which provides higher power density with reduced unsprung weight. Therefore, the gearless motor drive systems have promising potentials for electric and hybrid vehicles. With reference to typical gear-drive systems, this keynote aims to introduce the latest development of gearless electric motor drive particularly on electric and hybrid vehicles with a brief but comprehensive coverage of various topics.
