Sustainable Urban Mobility Plans (SUMPs) can help developed, developing, and transitional cities and countries to design more livable and prosperous cities for all, as well as reduce congestion, road fatalities, noise and air pollution, and CO2 emissions. SUMPs can assist in developing long-term urban green freight policy to guide regulatory development and infrastructure investments, and can require all major traffic generators to develop and implement site-based mobility plans to manage their accessibility.
- SUMPs can apply equally to passenger and freight transport, and can be more effective when passenger and freight are combined within a comprehensive planning process.
- SUMPs include all urban transport modes, including walking, cycling, public transport, private vehicles, and freight vehicles.
- SUMPs have the potential to significantly reduce GHG emissions in urban areas by creating a more integrated urban mobility system, which helps to avoid unnecessary transport trips, shift passengers and goods to more efficient modes, and reduce trip lengths by improving access to key destinations. By increasing motorized and non-motorized transport options, SUMPs in effect can increase resiliency by increasing transport system redundancy.
- A SUMP seeks to contribute to the development of an urban transport system which is accessible and meets the basic mobility needs of all users, as well as balancing and responding to the diverse demands for mobility and transport services by citizens, businesses and industry, thus meeting the needs for economic viability, social equity, health, and environmental quality.
Status of deployment:
- The Cooperation for Urban Mobility in the Developing World (CODATU) ‘MobiliseYourCity’ initiative aims to engage at least 100 cities in elaborating a SUMP between 2016 and 2020 for both passengers and freight, reduce CO2 emissions at least 50% by 2050, and build capacity to implement national sustainable urban mobility policies at the local level in 12-15 developing countries.
- WBCSD and 15 member companies have developed the Sustainable Mobility Project 2.0, a globally applicable, data-driven multi-stakeholder approach for developing SUMPs. This process has been tested in Chengdu, Bangkok, Indore, Hamburg, Lisbon and Campinas.
- In 2001 Budapest adopted a development plan for a city transport system, which was reviewed in 2009. In 2013 the city decided to reconsider the entire strategic planning process and develop a new transport development strategy for Budapest, the Balázs Mór Plan (BMT).
- The Green Zone for Transport in Santiago promotes sustainable urban transport through four initiatives: promoting zero or low emissions vehicles; developing a more efficient public transport system; promoting non-motorized transport; and increasing pedestrian spaces.
- In many cities, transport is the largest or second-largest source of local air pollutants such as CO, SO2, NOx, and PM. Urban air pollution is now linked to up to one million premature deaths and one million pre-native deaths each year, which accounts for approximately 2% of GDP in developed countries and 5% in developing countries. Traffic congestion is another key source of urban transportation externalities with a share of 1-5% of GDP.
- Planning sustainable urban mobility can contribute significantly to the reduction of urban transport externalities. For example, the EU Commission has estimated that the implementation of the comprehensive set of recommendations from the SUMP process in a given city can lead to a CO2 emission reduction of between 35% and 70% by 2040, with projected savings in public and private capital and urban transport operating costs in excess of $100 trillion until 2050, and a potential reduction of about 6% of global transport CO2 emissions by 2030.
