For most sectors there is a need to consider a set of additional policy measures in order to pursue a more ambitious low carbon path and achieve carbon neutrality by 2050. With regards to the additional policy scenario (or neutrality scenario), unlike the previous one, emission restrictions consistent with carbon neutrality were imposed in 2050. This scenario thus allows to assess the additional effort required for each sector so that overall achieve neutrality, not accurately translating a typical scenario of policy impact assessment and planned measures. There is still a cost-effective potential to reduce GHG emissions more sharply compared to the existing policy scenario, around 55% compared to 2005, rising to 73% by 2040 and around 82% by 2050 (without LULUCF), decarbonizing almost entirely electricity production, and strongly reducing emissions from mobility and transport and buildings, over the next decades. Thus, the electricity generation sector in an additional policy scenario has in 2030 a GHG emission reduction potential of around 95% compared to 2005, the transport sector by 46% and the building sector by 48%, rising to 98%, 84% and 82% respectively by 2040. As for the industrial processes sector, reductions of around 39% in 2030 to 48% in 2040 are expected, due to the expected improvements in process efficiency and the use of less polluting fuels, with the incorporation of more Fuels Derived from Waste/ RDF (refused derived fuel), biomass and electrification of some subsectors.
