Human consumption and activity are damaging the global ecosystem and the resources on which we rely for health, well-being and survival. The COVID-19 crisis is yet another manifestation of the urgent need to transition to more sustainable societies, further exposing the weaknesses in health systems and the injustice in our societies. It also underlines that many of the factors leading to environmental degradation, ill health and social and health inequities are interlinked. The current situation provides an unprecedented opportunity to invest in initiatives that address these common factors and encourage people to live more healthily and sustainably. Such initiatives can generate the positive feedback loops needed to change the systems and structures that shape our lives. INHERIT (January 2016–December 2019), an ambitious, multisectoral and transnational research project that involved 18 organisations across Europe, funded by the European Commission, explored such solutions. It identified, defined and analysed promising inter-sectoral policies, practices and approaches to simultaneously promote environmental sustainability, protect and promote health and contribute to health equity (the INHERIT “triple-win”) and that can encourage and enable people to live, move and consume more healthfully and sustainably. It also explored the facilitators and barriers to working across sectors and in public private cooperation. The insights were brought together in guidelines setting out how policy makers can help instigate and support local “triple-win” initiatives that influence behaviours as an approach to contributing to the change that is so urgently needed to stem environmental degradation and the interlinked threats to health and wellbeing. This article sets out this guidance, providing timely insights on how to “build back better” in the post pandemic era.

The world’s challenges of climate change, damage to ecosystems, and social and health inequalities require changes in human behaviours at every level of organisation, among governments, business, communities, and individuals. An important question is how behaviour change can be enabled and supported at the scale and speed required. The research reported in this paper describes important lessons for good practice in changing contexts to modify behaviours for a triple win for health, equity and environmental sustainability. Authors synthesised learning from qualitative, quantitative and cost benefit evaluations of 15 case studies conducted in 12 countries in Europe. The case studies address ways of living (green spaces and energy efficient housing), moving (active transport) and consuming (healthy and sustainable diets) that support the triple win. Ten lessons for good practice were identified. These include bringing a triple win mindset to policy and practice in planning interventions, with potential to improve environmental sustainability, health and equity at the same time. The lessons for good practice are intended to support governmental and non-governmental actors, practitioners and researchers planning to work across sectors to achieve mutual benefits for health and environmental sustainability and in particular to benefit poorer and more socio-economically disadvantaged groups.
