South Africa flagship on green mobility: Johannesburg Metrobus, Part I - Greening the future fleet

This research focuses on an emissions control strategy for the Metrobus fleet in Johannesburg, South Africa. While Metrobus has not set any fleetwide emissions reduction targets, both the Johannesburg Integrated Development Plan (IDP) for 2017/2018 and South Africa’s National Green Transport Strategy (GTS) have endorsed deployment of diesel dual-fuel (DDF) engines as a key technology solution for reducing greenhouse gas (GHG) emissions. DDF technology converts a diesel engine into a dual diesel and compressed natural gas engine, and the national GTS is South Africa’s government plan for the sector in support of meeting its nationally determined contribution under the Paris Agreement.
