Figure 5.1 | Low Energy Demand Scenario needs no BECCS and needs less decarbonisation effort. Dependence of the size of the mitigation effort to reach a 1.5°C climate target (cumulative GtCO2 emission reduction 2020–2100 by option) as a function of the level of energy demand (average global final energy demand 2020–2100 in EJ yr –1) in baseline and corresponding 1.5°C scenarios (1.9 W m–2 radiative forcing change) based on the IPCC Special Report on Global Warming of 1.5°C (data obtained from the Scenario Explorer database, LED baseline emission data obtained from authors). In this figure an example of remaining carbon budget of 400 Gt has been taken from Rogelj et al. (2019) for illustrative purposes. 400 Gt is also the number given in Table SPM.2 (IPCC 2021, p. 29) for a probability of 67% to limit global warming to 1.5°C.
