In scenarios 1 and 2, end users of energy such as transport, industry, and buildings are decarbonised extensively, while accounting for residual emissions in aviation and baseline assumptions on the technological potential for carbon capture. In this scenario more optimistic assumptions around carbon capture and aviation, such as the availability of sustainable fuels at scale and zero emission aircraft, cause a divergence from scenarios 1 and 2 in the deployment of certain technologies. With lower residual emissions in aviation and improvement in capture or negative emission potential, end use sectors such as transport, buildings, agriculture and industrial dispersed sites can decarbonise to a lesser extent. This pathway sees electricity and low carbon hydrogen generation requirements in between the two scenarios explored previously, at 670 TWh and 330 TWh respectively.
