The acceleration of climate change we are seeing is triggering one of the deepest and most threatening global crises to ensure a fair and livable planet for the more than 8 billion inhabitants and for the biosphere. The climate crisis is so significant and severe that climate emergency is already being discussed. We are in a global context in which the trespassing of planetary boundaries, particularly those related to climate emergency, has clear effects on our daily lives, especially in an uneven and unfair manner. Organizations, across their diversity, cannot circumvent the necessary debate on how they must adapt to the new climate emergency context and how they can contribute effectively to mitigation and adaptation, without falling into greenwashing. New metrics, beyond current green certifications, that can capture and incentivize the decarbonization and ecological transition of organizations will need to be found. Obviously, this requires a profound change in the continuous economic growth logic that transcends the individual wills of organizations and requires profound social, cultural and political-economic change in the priorities we have as a society.

For a sustainable post-Covid-19 recovery strategy, humanity faces two major challenges: 1. Just prosperity: The creation of a resilient and fair economy that delivers prosperity for all; 2. Public and planetary health: protect human health, together with the reduction of environmental impacts below thresholds of planetary boundaries including greenhouse gas emissions. The Covid-19 crisis could represent an opportunity for responses that integrate different goals, or a drawback if some are prioritized without considering their impacts on the others. New kinds of informed solutions are needed to ensure long-term sustainability in social, economic, and environmental terms. This article addresses the research question: How could developed countries manage a sustainable recovery that provides a good life for all within public and planetary health? First, it argues that economic growth is not compatible with environmental sustainability. Green Keynesianism is based on the hypothesis that economic growth can be decoupled from environmental impacts, but this has not happened and it is unlikely to happen. Second, it introduces degrowth as an alternative to green growth. Degrowth challenges the hegemony of economic growth and calls for a democratically led redistributive downscaling of production and consumption in industrialised countries as a means to achieve environmental sustainability, social justice, and well-being. Third, it traces the recent evolution of the term degrowth from an activist slogan to an academic concept. Last, it calls for an alliance of alternatives that could foster a deeply radical socio-ecological transformation.
