Despite increased awareness of the urgency to respond to climate change and to promote sustainable development, there are few powerful initiatives that are decisively shifting urban development in a sustainable, resilient and low-carbon direction. This Special Volume of the Journal of Cleaner Production explores sustainable urban transformation focusing on structural transformation processes-multi-dimensional and radical change-that can effectively direct urban development towards ambitious sustainability goals. The 20 articles are based on 35 cases and over 130 surveyed examples of urban initiatives on sustainability in many countries. While cities in Europe dominate, there are also examples from North America, South America, Africa, Asia and Oceania. The combined articles in this Special Volume contribute to knowledge and understanding on sustainable urban transformation across a range of areas, including governance and planning, innovation and competitiveness, lifestyle and consumption, resource management and climate mitigation and adaptation, transport and accessibility, buildings, and the spatial environment and public space. Overall, this Special Volume documents and analyses real-life action in cities and communities around the world to respond to sustainability challenges and it provides critical insights into how to catalyse, intensify and accelerate sustainable urban transformation globally. A main finding of the articles is that governance and planning are the key leverage points for transformative change.

It is urgent in science and society to address climate change and other sustainability challenges such as biodiversity loss, deforestation, depletion of marine fish stocks, global ill-health, land degradation, land use change and water scarcity. Sustainability science (SS) is an attempt to bridge the natural and social sciences for seeking creative solutions to these complex challenges. In this article, we propose a research agenda that advances the methodological and theoretical understanding of what SS can be, how it can be pursued and what it can contribute. The key focus is on knowledge structuring. For that purpose, we designed a generic research platform organised as a three-dimensional matrix comprising three components: core themes (scientific understanding, sustainability goals, sustainability pathways); cross-cutting critical and problem-solving approaches; and any combination of the sustainability challenges above. As an example, we insert four sustainability challenges into the matrix (biodiversity loss, climate change, land use changes, water scarcity). Based on the matrix with the four challenges, we discuss three issues for advancing theory and methodology in SS: how new synergies across natural and social sciences can be created; how integrated theories for understanding and responding to complex sustainability issues can be developed; and how theories and concepts in economics, gender studies, geography, political science and sociology can be applied in SS. The generic research platform serves to structure and create new knowledge in SS and is a tool for exploring any set of sustainability challenges. The combined critical and problem-solving approach is essential.
