Plafond de concentration en carbone et substitutions entre ressources énergétiques

Fossil fuel use causes the atmospheric accumulation of carbon. The society, endowed with an alternative clean renewable energy, aims at keeping this pollution stock below a prescribed target. The use of an abundant and costly backstop shall follow the exhaustion of the polluting resource; in case of a cheap and abundant substitute, both resources may be exploited simultaneously. When the substitute is scarce, the phase of simultaneous exploitation may occur before the ceiling is reached.
