This paper examines how PASCAL EcCoWell 3 could be further developed as a path to a sustainable future in a turbulent period of disruptive change. The paper draws on the 2021 UNESCO Reimagining the Future Together report in its assessment of the critical situation confronting humanity and the planet requiring transformation of the world towards “a more just, equity, and sustainable future.” In assessing how the PASCAL EcCoWell approach to integrated holistic development could be taken further as a response to the critical situation identified by UNESCO, this paper discusses the three stages of EcCoWell development since 2012 leading to the 2020 EcCoWell Community Recovery Programme which identified several ways in which the EcCoWell concept could be further developed as an approach for learning cities to a just and sustainable future. In examining possible future directions for EcCoWell, this paper considers the relevance of the following approaches to a sustainable future: This analysis led to the following conclusions: These developments should lead to a revitalisation of the EcCoWell approach to holistic sustainable development in cities and communities. The EcCoWell concept was set out by Peter Kearns in a 2012 paper, revised in 2013, and ranged across the following five domains: Ecology, Economy, Community, Well-being, and Lifelong Learning. Its core theme brings together sustainability objectives, and the traditional learning objective of opportunity.
