Baroness Bennett of Manor Castle (GP)
My Lords, the Jet Zero Strategy reports:
“Non-CO2 impacts currently represent around 66% of the net effective radiative forcing”
of aviation—the global warming potential of flying—and notes that the Department for Transport analysis does not take any account of these outputs of water vapour and nitrous oxide at high altitudes. Instead, it commits to a five-yearly review of the evidence. How will the Government deliver net-zero aviation if these effects are found to be significant even with non-fossil fuel aviation fuels?
Baroness Vere of Norbiton (Con)
For once, I agree with the noble Baroness. Non-carbon dioxide emissions are incredibly important, yet the science is as yet unresolved. There are significant uncertainties around the impacts of all the different emissions produced by aircraft, particularly at high altitude. We are looking at the research and will be developing policies once we have had more time to consider where the science currently is.
