Lisbon: Câmara Municipal de Lisboa Electric Vehicles Fleet

Lisbon is the capital city of Portugal, with a resident population of 547,773 inhabitants. The city is situated on the right bank of River Tagus, in the heart of the country, being its political and major economic centre, presenting a cosmopolitan dynamic as a result of the hundreds of daily movements registered by its floating and resident population.

The context

The Lisbon municipality has been actively involved with aspects related to energy efficiency within the transport sector over the past years,, being part of the ambitious National Program for Electric Mobility in Portugal (MOBI.E) that intends to set-up a nation-wide intelligent charging network, and under which almost 500 charging points were installed in the city by the end of 2011. Based on this, the municipality has been placing huge efforts in a long-term strategy that envisions a city with high environmental standards, and the municipality intends to lead by example. Other relevant Lisbon commitments, namely the Covenant of Mayors and the Environmental and Energy Strategy, are some of the natural arguments to develop a comprehensive strategy that could lead to increasing usage of electric vehicles in its fleet.

Lisbon's case study will assess the usage potential of electric vehicles in the municipal fleet and how this example can boost the market penetration of such technology. It is aimed at supporting the municipal fleet renewal strategy so that electric vehicles are rationally integrated in the operations and an effective uptake of this new technology is undertaken within the municipality.

The local partners Occam and the municipality of Lisbon will address aspects such as the market uncertainties related to the potential of the new technology, the lack of confidence and familiarity with electric vehicles of the users and the need for an integrative and engaging communication strategy to raise awareness about the municipal electric mobility plans. 

The tasks

The case study runs from April 2013 until March 2016.

Fleet activity scan

The definition of a baseline scenario is the primary task of this case study, necessary not only for the development of the subsequent activities, but also for its overall evaluation at the end of the project. The fleet activity scan will consist on the analysis of the fleet composition and performance, in order to have a diagnosis that will allow the identification of existing intervention opportunities. This diagnosis will imply the collection of several data from the fleet operation covering usage characterization, energy consumption and costs.

Fleet renewal plan

Based on the results of the fleet scan and the operational needs of the municipality for an effective and efficient accomplishment of its daily activities, a renewal plan will be developed in order to minimize the environmental impact and optimise the energy consumption of the fleet.

Configurations for vehicle allocation

Different configuration schemes for the fleet will be developed and evaluated in order to assess what's the most effective solution to be implemented by the municipality (e.g. pool of vehicles versus vehicle allocation to a single user).

Testing and monitoring

The demonstration period also includes the monitoring and validation of the different electric vehicles usage configurations previously defined. These will involve the collection of operational data (e.g. distances travelled by vehicles and energy consumption) as well as behavioural aspects through the implementation of focus groups and surveys to better understand the users expectations and opinions on electric vehicles, their willingness to buy them, capacity to fulfil their daily activities, among others.


During the project lifetime several communication activities will also be promoted to engage citizens and local companies, in order to encourage the use of electric vehicles outside the municipality and thus contribute to an increase in the market share of these new technologies.

Assessment of impacts

Conclusions and recommendations will be prepared to support the council's decision makers in future strategies based on the assessment of impacts of the tested configurations previously considered, namely for aspects such as energy consumption, GHG and pollutants emissions and costs. Furthermore, remaining market barriers and potential for behaviour change will also be analysed.

The goals

The Lisbon case study has the overall goal of facilitating decision-making towards electric vehicles. The pilot will explore different configurations for the allocation of electric vehicles and the type of operational functions, to better understand the highest potential of electric vehicles for municipal operations and promote electric vehicles in future decision-making.

More concretely, several specific targets must be achieved at the end of the project:
• Reduction of CO2 emissions of the municipal passenger car fleet
• Increased energy efficiency of the municipal passenger fleet
• Foster users preferences for electric vehicles
• Reduction of air pollutants of the municipal fleet
• Increase the sales of electric vehicles.
