Executive Summaries






Deep-dive papers

As part of the Earth4All project, collaborators have submitted deep-dive papers
to delve further into the issues and solutions needed to transform our economic system
and provide an equitable future for all on a finite planet.

Richard Wilkinson and Kate Pickett explore large income and wealth differences, and how those differences reduce the chances that our societies will respond adequately to the environmental crisis. It details six reasons for why greater equality is essential to a world facing the consequences of overshoot and the climate crisis.

The World3 model was used by the authors of The Limits to Growth in 1972, and this paper sets to conduct a quantitative comparison between empirical data and the most recent version of World3 scenarios to see if we are still following the business as usual scenario.

This paper details five extraordinary turnarounds to address the environmental, ecological and socio-economic problems we face. It also explores the financial opportunities and costs in implementing the necessary actions.

Debamanyu Das, Shouvik Chakraborty and Jayati Ghosh investigate focus the possible adverse effects of well-meaning climate mitigation strategies, and consider how these adverse effects can themselves be mitigated.

Ken Webster proposes sharing the earth’s fruits and redistributing the proceeds to all. The paper asks, what and how to produce, and who gets the benefits?

This paper explores how to emerge from the multiple existential planetary emergencies, making three recommendations for transformative change. It also outlines why a living systems approach is needed to achieve global equity for a healthy planet.

In this paper, Jayati Ghosh, Shouvik Chakraborty, Anuar Sucar Diaz Ceballos and Adrina Ibnat Jamilee Adiba argue that recognising and addressing existing global inequalities is central to addressing the climate challenge.

This paper by Masse Lô proposes that the only way to prevail against the threats facing humankind is by living by the philosophy inspired by Zulu/Bantu term Ubuntu. That is, “a country becomes a country through other countries”.

This paper by Nafeez Ahmed explores new possibilities that could empower humanity to solve some of its most intractable problems: energy scarcity and volatility, the persistence of food insecurity and malnutrition, global poverty, and widening inequality.

Chandran Nair explores what transformations and trade-offs will be needed in a resource-constrained 21st century to reverse our supercharged self-disruptive trajectory.

Otto Scharmer explores how to transform the 21st-century economic system to become more just and sustainable. He argues for the need to create a learning infrastructure to make this transformation possible.

The authors argue that the mismanagement of these natural resources is the common cause of climate change, biodiversity loss, and pollution or health impacts. Furthermore, by identifying the root causes of these crises, together we can deliver policy responses that tackle them effectively.

Luana Schwarz, Jannes Breier, Jonathan Donges and Johan Rockström, as part of the Earth4All modelling team at PIK, explore the key dynamics for the realization of a global-scale transition to regenerative agriculture.

Members of the Earth4All modelling team show that global population could peak just below 9 billion in 2050 in this special report for the Global Challenges Foundation.

Version 1.1 corrects some inconsistencies between figures 11-14.3 and their captions and descriptions in the main text. This does not affect the conclusions of the report.

Members of the Earth4All modelling team track development of relevant indications for the Sustainable Development Goals 1-7 against GDP in seven world regions and globally.

Randers, J., Rockström, J., Stoknes, P., Golüke, P., Collste, D., and Cornell, S., (2018) Transformation is feasible: How to achieve the Sustainable Development Goals within Planetary Boundaries. A Report to The Club of Rome.

This report explores different pathways for the implementation of the Sustainable Development Goals (SDGs). It confirms that meeting the SDGs in an integrated fashion based on conventional growth policies is not possible. The only way to meet most of the goals by 2030 is to take transformational actions with system-wide effects.

This report was the first to model our planet’s interconnected systems and to make clear that if growth trends in population, industrialisation, resource use and pollution continued unchanged, we would reach and then overshoot the carrying capacity of the Earth.
