I think I said fuels produced from nuclear energy, but never mind.
The RTFO already includes criteria to ensure that renewable energy used for fuel production is additional to that which would otherwise be supplied, and the same principles would be developed for nuclear power.
With regards to the waste hierarchy, this policy makes effective use of what otherwise would be difficult to manage waste. RCFs are non-recyclable fossil wastes. Utilising these types of wastes to synthesise fuel is a better end-of-life fate than landfill or incineration. It will be important to mitigate risks and ensure adherence to the UK waste hierarchy, so we are in the process of concluding a consultation on detailed policy proposals to ensure that RCFs contribute to and meet our wider objective of effectively reducing the greenhouse gas emissions of fuels. Sustainability criteria are being carefully formulated in consultation with a wide range of scientists, technical experts, other government departments, fuel suppliers and wider stakeholders to ensure that the risks are carefully managed and mitigated. I hope that provides appropriate reassurance to the noble Baroness.
