pteg represents the six Passenger Transport Executives (PTEs) which plan, procure, provide and promote public transport in some of Britain’s largest city regions. pteg is also a wider professional network for Britain’s largest urban transport authorities. The pteg network has a long track record of investment in low carbon vehicle technologies, including the trialling of alternative fuels, involvement in Plugged-In Places schemes and the procurement of green buses. The city regions have achieved success across all four rounds of the Green Bus Fund which will see over 450 green buses enter service in the PTE areas. In addition, pteg has commissioned and published a number of studies to help PTEs and other transport authorities make the best choices when it comes to low carbon vehicles, from our carbon pathways report to our most recent commission looking at the contribution of urban transport to air quality.
