Earth4All is an international initiative launched in 2022 that aims to promote transformational systems change for sustainable development and social equity within planetary boundaries..[1] The project builds upon the legacy of The Limits to Growth report from 1972 and is convened by the Club of Rome, the Potsdam Institute for Climate Impact Research, the Stockholm Resilience Centre and the BI Norwegian Business School.

Background

[edit]

The initiative emerged from discussions among economic thinkers, scientists, advocates and policy experts about the need for new models to address 21st-century challenges. It was conceived as a follow-up to the influential Limits to Growth study, which used computer modelling to examine the implications of exponential economic and population growth with finite resources.

Main components

[edit]

Earth for All: A Survival Guide for Humanity

[edit]

The initiative's cornerstone publication, Earth for All: A Survival Guide for Humanity (2022)[2], presents analysis and recommendations based on state-of-the-art computer modelling. The book is co-authored by Sandrine Dixson-Declève, Owen Gaffney, Jayati Ghosh, Jørgen Randers (co-author of The Limits to Growth), Johan Rockström and Per Espen Stoknes, with a foreword by climate activist Elizabeth Wathuti. It outlines five "extraordinary turnarounds" needed to achieve sustainable prosperity and wellbeing on a finite planet:

  • Eliminate poverty
  • Reduce inequality
  • Empower women
  • Transform food systems
  • Transform energy systems

The analysis stresses that these turnarounds must be implemented simultaneously in order to achieve the desired outcomes.

Alongside the five turnarounds, the book proposes a transformation of the current economic system to one that prioritises human and planetary wellbeing above economic growth.  

The book has been published in 11 languages and the Argentinian version was recognised in 2024 as a book of legislative interest by the City of Buenos Aires[3]. A further book applying the Earth4All modelling to Germany, Earth for All: Germany was published in October 2024 and reached number nine on the Der Spiegel nonfiction bestseller list[4].

System dynamics modelling

[edit]

Earth4All employs system dynamics modelling to analyse potential future scenarios. The model is based on the World4 computer simulation model, an updated version of the World3 model used to produce The Limits to Growth. The project developed two main scenarios:

  • "Too Little Too Late" - modelling current policy trajectories
  • "Giant Leap" - modelling transformative policy changes

These scenarios are detailed in the book Earth for All: A Survival Guide for Humanity and are used by the Earth4All initiative as a basis for policy proposals to achieve the "Giant Leap" scenario. In this scenario, rapid global cooperation to enact the five "extraordinary turnarounds" results in stabilised temperatures, reduced material use, and the end of extreme poverty. According to the model, in this scenario social tension falls, inequality is reduced, and wellbeing rises.[2]

The computer modelling, alongside the Millennium Institute's iSDG model[5], has since been used to model these scenarios for Kenya[6], Germany[7] and Austria[8], and to analyse pathways towards the SDGs in Sub-Saharan Africa[9] and globally.[10]

The global[11] and regional[12] models are available open source and are subject to ongoing academic analysis and discussion[13][14][15].

Reception and impact

[edit]

The book and initiative have generated discussion across academic[13][14], policy, and public spheres since its launch. It was featured prominently at the 2023 European Parliament "Beyond Growth" conference, with Executive Chair Sandrine Dixson-Declève giving a keynote address[16]. Its 2024 research[17] into public attitudes to progressive tax policies was quoted by influential economist Gabriel Zucman in support of a G20 initiative for a global wealth tax[18][19]

Its analysis has influenced a broad range of organisations and initiatives, from H&M Foundation[20][21] to the European Youth Orchestra, who based its 2023 tour on the initiative[22]. In 2023, Italian newspaper La Repubblica dedicated its annual Green&Blue festival to Earth4All.[23][24]
