In the following pages, we give a short introduction to a new integrated global assessment model: The Earth4All model of human wellbeing on a finite planet towards the year 2100. The Earth4All (E4A) model has evolved over a fifteen-year period and represents a summary of insights we have gained during all these years (See Appendix 1 for a list of the main publications that form the foundation for the Earth4All model.) The full set of model equations are freely available (as a Vensim or Stella file) on the web.
