Scottish Ultra-Low Emission Bus Scheme

The Scottish Ultra-Low Emission Bus Scheme (SULEBS) was an evolution of the Scottish Green Bus Fund held each year between 2011 and 2018.

SULEBS supported the Scottish Government’s net zero targets, its commitment to delivering Low Emission Zones and Scotland’s ambitions for transport decarbonisation.

It provided support for the purchase of new ultra low emission buses up to a maximum 75% of the differential costs against diesel buses, depending on their zero emission running capability. Support was also available for the infrastructure for this technology of up to a maximum 75% of the capital cost.

The first round of SULEBS ran in August 2020. Over £10.1 million of funding supported four completed bids, for the introduction of 57 ultra-low emission buses, and supporting infrastructure.

The second round of SULEBS ran in January/February 2021. Over £40.5 million of funding will support six completed bids, introducing a further 215 ultra-low emission buses, and supporting infrastructure across Scotland.

Further support for transition to zero emission buses has been offered under the Scottish Zero Emission Bus Challenge Fund (ScotZEB) which opened for bids on 4 August 2021.
