Tokyo's long-term socioeconomic pathways: Towards a sustainable future

Three alternative Tokyo future pathways by 2050 were established. The Local Vitality scenario and the Efficiency scenario belong to the sustainability scenario in the SSPs, with a comparison with the business as usual (BAU) case. An important feature of such a city-scale scenario is to address urban form elements and infrastructure. The elements used for Tokyo can be applied for other cities. Projecting the future is fraught with a number of uncertainties, however, describing possible pathways can provide significant support for developing sustainable mechanisms for society as a whole. This work can lay the groundwork for developing further quantitative approaches to examine strategies for reducing environmental and societal impacts in different pathways.
