Titre : Environmental and Social Crisis: an Indicator of Living Conditions and a Long-term Economic Program for France Auteurs : Pierre Le Masne, Revue : Technology and Innovation Numéro : Issue 2 Volume : 11 Date : 2026/03/13 DOI : 10.21494/ISTE.OP.2026.1428 ISSN : 2399-8571 Résumé : Contrary to popular belief, improving the ecological situation does not necessarily imply a decrease in GDP. It is first necessary to reassess the importance of the free use values of nature, and to construct a Living Conditions Indicator that takes these use values into account. Then a long-term economic program (2026-2050) is proposed, which allows for an ecological reconversion associated with an improvement in the living conditions of the population (in particular the reduction of working hours). It is based on a strong increase in labor productivity, favored by a strong investment, coupled with moderate economic growth and a drastic reduction in all kinds of inequalities.
