The common aim that brings these organisations together is to progress towards sustainable and safe mobility, with the commitment and joint responsibility of everyone.

In 1998 around thirty organisations, as well as Barcelona City Council itself, formalised and adopted the Mobility Pact to express their commitment to city mobility. Since then, the Pact has contributed to boosting initiatives and reaching consensus on actions to improve the mobility and safety of the city streets. Some hundred mobility-linked associations, companies, institutions and public bodies are part of the Mobility Pact. They have a permanent committee as the Pact’s managing body.

The Pact enshrines the following principles:

• The principle of sustainability. Now and in the future we need mobility that makes the environment and people less aggressive, and that increases planning, efficiency, saving resources and respect for the environment.
• Mechanisms need to be established to defend everyone's right to mobility.
• It is necessary to guarantee the quality of life of all citizens.
• It is necessary to encourage a change of attitude on the part of local authorities and citizens, through systems that guarantee road safety and discipline.
• It is necessary to design new urban development projects so they satisfy the mobility needs they generate.
