A Social Guarantee for transport means building a reliable, inter-connected, affordable public transport system that takes people where they need to go. Transport for London runs an integrated transport system with free passes for children under 12, disabled passengers and residents over 60, as well as discounts for students, claimants and others. It is a statutory body created by the Greater London Authority, operating in the public interest without profit extraction. Another example comes from Tallinn, Estonia, where free public transport is provided for all city residents. The scheme covers tram lines and trolley bus lines, a wide range of bus routes and some commuter trains. It aims to make transport more inclusive, stimulate the labour market, increase consumption of local goods and services, reduce private car traffic and attract more residents paying taxes to the city, to offset costs.
