An interesting possibility which seems to be under consideration.
If a motorist drives 1,200 miles a year, the fee they pay per mile would be channelled towards supporting high quality, ethical carbon credit projects around the world.This would include afforestation and the restoration and protection of vital carbon rich peatlands and grasslands.
Update:- The scheme, launched on 15 December 2021, offers individuals, clubs and those organising events within the historic vehicle community a quick and convenient way to carbon balance their emissions thanks to the planting of new woodland here in the UK. Importantly, that woodland will also be planted using native species to best contribute to the local ecosystem. Planting in this way also delivers a host of additional benefits, including increased biodiversity, creation of recreational spaces and flood mitigation to name a few.
