In the search for a social value of carbon. Analytical, digital and epistemological autopsy of an attempt of integrated modelling of climate

This academic study aimed at understanding the nature of the speech and knowledge produced by environmental economists about carbon social value, and at assigning them with a realistic mission in compliance with their abilities. A first part presents and discusses growth models with a carbon cycle with an increasing complexity. This part also comprises a calculation of the social discount rate and a comparison in its canonical shape. The second part reports the development of a simpler calculation method in order to overcome analysis limitations.
