The IPCC Special report on “Global Warming of 1.5 °C” identifies the greenhouse gas emissions trajectories compatible with the global mitigation goal of the Paris Agreement, presents the mitigation actions required to follow these trajectories and analyses the synergies and trade-offs with sustainable development objectives. The assessment highlights the necessity to implement drastic global carbon emissions reductions in the short term, to reach global carbon neutrality between 2050 and 2070 and to implement targeted actions to limit other greenhouse gases. To this aim, rapid and far-reaching transformations are required in energy, industrial, infrastructure and land-use systems. Adopting systemic strategies combining policy packages elaborated according to the specificities of each country context and with a long-term perspective is a requirement for ensuring that these low-emission transformations can be compatible with the achievement of socio-economic and development objectives.
