To avoid the most dangerous effects of climate change, the Paris Accord requires large cut in greenhouse gas emissions and thus a deep transformation of the energy system worldwide. Emissions reduction should be very fast, much faster than what imposed by previous commitments, and the feasibility and the timing of these reductions are under discussion.
In this session the feasibility and techno-economic implications of ambitious mitigation scenarios will be discussed, both at the global level than for Italy. Evaluating the role of the portfolio of different technology options, negative emissions, R&D investments, land use, and the related uncertainties, allow to understand the tremendous scale of the challenge that has to be faced in the next years and decades.
