Any serious plan to avoid climate breakdown must include measures to significantly reduce the use of fossil fuels for transport - particularly air and road. But financial measures such as green taxes or removal of subsidies are unfair and politically dangerous, as shown by the "gilets jaunes" protests in France in 2019. I strongly believe that an alternative approach of actively monitoring and managing the amount each of us travel would be fairer, more acceptable to the travelling public and entirely feasible. A Labour policy of investigating the viability of such schemes as an alternative to green taxation, would be more in-line with Labour values and more likely to succeed in practice.
I wrote an unpublished paper about one possible scheme (attached) in an attempt to convince others of the viability of such approaches. To be clear in my spare time and with no commercial motive.
