In Australia, various City Councils, including the City of Adelaide, are pursuing carbon neutrality at municipal-scale based on their operational greenhouse gas (GHG) emissions. As passenger transport is a major component of city operational GHG emissions, there is an opportunity for shared mobility services to play a role in reducing those emissions. This preliminary carbon modelling report has focussed on the GHG benefit from expanding shared mobility services in the Adelaide Local Government Area, although the results should be equally valid in other similar inner-urban precincts.
