#20 - Require consultation on airspace-wide contrail avoidance and account for non-CO2 aviation effects.
Within six months of the publication of this report the Government must consult on airspace-wide contrail avoidance measures. Furthermore, given the significant role that non-CO2 effects play in global warming, the Government must account for these in its assessment of the overall impact of the aviation sector. (Recommendation, Paragraph 82)

#19 - Reducing non-CO2 aviation effects like contrails crucial for achieving net zero
Whilst a reduction in aviation emissions is necessary to deliver a net zero aviation sector, an important contribution to the UK’s efforts is the reduction of non-CO2 effects, such as contrails. (Conclusion, Paragraph 81)

The Government should set out in its response to this report what work and research it is supporting to reduce non-CO2 emissions that damage air quality around airports. It should also confirm whether it has identified which current aircraft have the least impact on air quality around airports.

#22 - Include funding for research into non-CO2 atmospheric effects of zero-emission flight technologies.
Zero-emission flight is sometimes described as providing ‘guilt-free’ flying. While it is the case that ZEF technologies remove the CO2 emissions from conventional aircraft movements which are aviation’s most damaging effect on the environment, the potential effects on the atmosphere from both hydrogen and battery-electric flight are not fully known. We recommend that the Government, when promoting research...

#1 - Non-CO2 climate impacts of aviation remain unquantifiable and poorly understood
The impact of conventional aviation activity on climate is still not fully quantifiable. While the contribution of aviation to levels of atmospheric CO and other greenhouse 2 gases is quantifiable and substantial, the climate impact of other emissions from aviation is currently not well understood and difficult to quantify. Measures to decarbonise the sector are vital: but removing...

#8 - Significant potential exists for increased operational efficiencies in UK aviation to reduce CO2.
There is evidently significant potential for increased efficiencies across all aviation’s operations which can lead to incremental reductions in CO2 emissions across the UK aviation sector. Efficiencies from fuel use in the current and emergent fleet of aircraft, better use of airspace and reductions in emissions from airport and aviation operations will all have a significant part to...

We recommend that the Government sustain and enhance its engagement with the aviation industry on the delivery of operational efficiencies from current and future fleets of aircraft operating through the UK, to maintain the ambition to secure 2% year- on-year CO2 emissions reductions from fuel and operational efficiencies. The delivery of these reductions must be rigorously monitored against...

#20 - Zero-emission flight shows promising long-term potential for eliminating aviation carbon emissions.
Zero-emission flight represents a very promising long-term prospect for achieving reductions in the CO2 emissions from UK aviation. Unlike the use of SAF, zero- emission flight technologies hold out the promise of eliminating the carbon emissions entailed in aircraft movements. We are encouraged by the significant contributions to research and development in this sector which are being undertaken...

#13 - Sustainable aviation fuels offer emissions reduction, but reliance on nascent technology is high risk.
Sustainable aviation fuels may offer a means of reducing the carbon emissions attributable to the lifecycle of aviation kerosene from its production to its combustion, and the Government envisions a substantial role for SAFs. There is nevertheless potential for wide variability in lifecycle emissions across the general class of fuels which the industry currently terms ‘sustainable aviation fuels’....

There is considerable dispute over the desirability of policy measures which would reduce UK aviation emissions by reducing the demand for aviation services.

If the Government is to achieve its targets on net-zero aviation, new sustainability policies will be required for the aviation sector, which in turn will require robust regulation.

Nor do the various organisations within Defence separately report their emissions publicly, so gauging progress towards their targets is not yet possible.

#9 - Measuring total defence carbon emissions provides a gold standard for military reporting.
Measuring and reporting against the total defence carbon emission figure would support both the Government’s agenda of reducing emissions to net zero by 2050, but also provide a gold standard of military emissions reporting for other countries to emulate. Good practice would be to ensure these figures are independently verified.
