Recommendation 34

Ministers have committed to five-yearly reviews of progress against the Jet Zero Strategy’s targets, and have undertaken to take action to amend policy if it appears to be necessary. On the current timetable the first such review is to take place in 2027. This appears to us to be a relaxed timetable for policy review at what is a critical stage for an incipient policy. If a review in 2027 concludes that targets are unlikely to be met, the ensuing policy changes will only bear fruit in the early 2030s—arguably too late for the emissions reductions initially envisaged to be achieved.
