The following figure illustrates the trajectory of reduction of total GHG emissions for the 2030 horizon, in line with the commitment to achieve carbon neutrality by 2050. As already mentioned, the evolution of national emissions in different paths of carbon neutrality points to a very significant decarbonization of the national economy in the 2030 horizon, so it will be necessary to ensure that the various sectors of activity contribute to this objective. In this sense, all sectors have the potential to reduce emissions, although the same is not the same for all sectors and GHG, being largely dependent on the degree of maturity of technologies and their cost-effectiveness. Thus, in the next decade, decarbonisation is expected to be more pronounced in electricity production, transport and buildings. At the sectoral level, the following national targets were defined for the 2030 horizon (non-CELE sectors). Figure 14-Evolution of GHG emissions and reduction targets set for 2030 (Mt CO₂)
