The Government has raised its ambition for its own vehicle fleet, and committed for 100% of its car and van fleet to be zero emission by 31 December 2027. GCS is working towards this aim, and as vehicles become due for replacement GCS are procured zero emission or compliant ULEV vehicles with a balance between battery electric and petrol hybrid vehicles. Working within Procurement rules, GCS endeavours to support UK based manufacturers subject to operational requirements. It now operates a fleet of which 71% are zero emission, ultra-low emission or low emission vehicles. This is achieved through a blend of battery electric and petrol hybrids.
