DfT launches new technical consultation on its “jet zero” (ie. huge future SAF use) plans
The UK government currently does not have an aviation policy, and is aware that this will first require policy decisions on aviation carbon emissions. It hopes that air travel demand will not need to be reduced (the most effective way to control the level of emissions) but instead hopes for “jet zero” flying, largely using novel fuels. These are called SAF (sustainable aviation fuels) and the hope is that they emit less carbon, over their lifecycle, than conventional jet fuel. Now the government has opened a consultation which it calls “Further consultation on the updated evidence and analysis to inform the different pathways to achieve net zero aviation – or jet zero – by 2050.” It lasts until 25th April. There was an initial consultation on “jet zero” in July 2021. This consultation is technical (so not easy for most people to respond to). The consultation is unrealistically hoping there might be 50% of SAF use by 2050, with 27% of flights being “net zero” by 2050. It also assumes a continuous 2% increase in efficiency each year, and a 70% increase in air passengers (cf. 2018) when the earlier estimate was a 60% increase.
The Jet zero: our strategy for net zero aviation consultation published in July 2021 set out our vision and strategic framework for achieving net zero aviation by 2050.
New tools and information now available have allowed us to further develop our analysis, to inform our final jet zero strategy.
This consultation invites views on the new evidence and updated analysis described in the Jet zero: further technical consultation document and accompanying Jet zero: modelling framework.
In light of this additional evidence, if you have further comments on our approach to achieving jet zero by 2050, please respond to the questions at paragraph 1.6 on page 5 in the Jet zero: further technical consultation document.
All responses to this further technical consultation will be considered alongside responses to the initial jet zero consultation.
You only need to submit a response to this consultation if the updated evidence and analysis change your response to the initial consultation.
