A Low Emission Zone (LEZ) covering Glasgow city centre was introduced on 31 December 2018; the first phase of this applying solely to local service buses. In October and November 2018, to comply with the new emission standards, First Glasgow placed orders for 150 new buses from Falkirk-based Alexander Dennis, partly funded by the Scottish Green Bus Fund, a Transport Scotland subsidy. The new buses started coming into service from October 2018, many in route-specific coloured branding, with launch events organised involving buses being wrapped in model-style packaging.
