Capital Cities and Urban Sustainability examines how capital cities use their unique hub resources to develop and disseminate innovative policy solutions to promote sustainability. Cities are taking a leading role in defining a sustainable future at a time when national, state, and regional governments in several countries do not provide sufficient leadership. Capital cities stand out among cities as likely leading drivers in the effort to empower sustainable innovation as they provide a hub for connecting a variety of key constituencies. While acknowledging the successes capital cities have achieved, the international, multi-disciplinary contributors to this work discuss how there is room to do more and improve. The promotion of specific sustainability policies in crucial areas such as clean water provision, high tech innovation, public procurement contracting, and improving flood control in capital cities is examined through various global case studies. The examples range from relatively rich capital cities, such as Copenhagen, where the well-financed hub would be expected to succeed in generating sustainable policies, to poorer cities such as Phnom Penh, where such an optimistic outcome can seem less likely.

This issue of the GSoD In Focus explores the contribution that the Global State of Democracy (GSoD) Indices can make to the review of progress on the United Nations’ 2030 Agenda for Sustainable Development and the Sustainable Development Goals (SDGs). The GSoD Indices can be used to complement the official indicators of the SDGs, to acquire in-depth knowledge on trends in achieving the specific targets of individual SDGs. In this regard, the GSoD Indices can be used to provide data on the SDGs for poverty (SDG 1), hunger (2), health and wellbeing (3), education (4), gender equality (5), inequalities (10), sustainable cities and communities (11), peace, justice and institutions (16), and partnerships for the goals (17), as well as across the 2030 Agenda for Sustainable Development.

Local councils in the state of New South Wales (NSW) in Australia are starting to give serious consideration to how they can include ‘sustainability’ in their planning for the future. There is no statutory requirement to create a sustainability plan – and therefore no standard definition of what constitutes such a plan for local government in NSW. The same is true of the term ‘sustainability’, for which there is no standard or legislative definition. However, the NSW state division of Local Government Managers Australia (LGMA - a professional organization for council managers) has recently released a ‘Sustainability Health Check’ as a resource to assist councils in assessing their current performance and devising appropriate strategies and action plans for sustainability. In addition, several individual councils have used the opportunity provided by the state government’s Urban Sustainability Program to make a first attempt at developing a sustainability plan.
