Optimal energy investment and R&D strategies to stabilise Greenhouse Gas atmospheric concentrations
Bosetti, Valentina; Carraro, Carlo; Massetti, Emanuele; … - 2007
The stabilisation of GHG atmospheric concentrations at levels expected to prevent dangerous climate change has become an important, global, long-term objective. It is therefore crucial to identify a cost-effective way to achieve this objective. In this paper we use WITCH, a hybrid...
