T-1A1a-5 - Increase journey sharing

Background

IPCC WG3 definition: M-1A-5 - Shared Mobility.

Increasing the number of passengers per vehicle will reduce the number of cars in traffic, thereby reducing emissions. The average passenger per car when commuting (in England) was 1.2 passengers in 2018.
