- Valuation of sustainable "work-home" mobility

Use Case
November 4, 2022


Transport is a leading greenhouse gas emitting sector, accounting for 30% of emissions. In France, 93% of CO2 emissions from local travel are due to the car, which is used in the ⅔ cases.

7 out of 10 French people travel to work by car, 58% of home-work trips of less than 1km are made by car, and only 2% of working people travel to work by bicycle.

Transport is the 1st item of expenditure for a household (18% of the budget on average), ahead of food and housing. 1 French person in 4 has already turned down a job because there is no way to get there. Finally, in 80% of the territory, no local authority offers a solution for everyday transport.


Passed in December 2019, a law brings unprecedented investments in France: €13.4 billion over the period 2017-2022, with priority given to commuting. The law also reflects a desire to take advantage of the digital revolution to offer new services to users. Finally, it aims to use cleaner transport, with, in particular, the end of sales of carbon fossil fuel cars by 2040, the deployment of electric recharging and the development of low-emission zones.

More in detail, this law include in particular:

  • The development of alternative solutions to the private car proposed by local authorities over 100% of the territory, thanks to simpler, less costly tools that are better adapted to their needs, which they will now be able to implement: car sharing, transport on demand, autonomous shuttles, etc. To achieve this, the State is setting up funding and calls for projects: for example, €500M are being mobilised by the State over the period 2017-2022 to co-finance mobility projects with local authorities.
  • Putting home-work mobility at the heart of social dialogue in companies: it has become a mandatory topic of social negotiation to ensure that companies commit to facilitating their employees’ journeys. This support can take the form of a mobility voucher, based on the meal ticket model.
  • A sustainable mobility package, up to €500/year to go to work by carpooling or cycling: employers are now able to contribute to their employees’ travel costs through this package, which is exempt from tax and social security contributions.
  • An innovative cycling plan to triple its share of travel: creation of a €350 million cycling fund, fight against theft with the gradual generalisation of bicycle marking and secure parking, creation of a sustainable mobility package, generalisation of cycling skills at school, etc.
  • A plan to make carpooling an everyday solution, by allowing local authorities to subsidise carpoolers, by opening up the possibility of creating reserved lanes on the outskirts of metropolises, by setting up a sustainable mobility package, etc.


  • Create an incentive mechanism that values positive action by employees and goes beyond green washing.
  • Ensure that every euro of incentivizetion recieved is associated with an impact value.

Tipping point

Set up a platform to value the individual impact of employees and to have this impact financed by companies wishing to act in favour of the transition.

Implementing SmartB

A unique value proposition on the market enables its clients to implement the sustainable mobility package by providing its users with a tool that simplifies the declaration of journeys made. The service also allows employers to monitor the activity of employees and the real impact of these journeys on the company's CSR policy while respecting the privacy of each individual.

Unlike the majority of its competitors who have set up "meal tickets" for mobility and have taken maximum advantage of the windfall effect introduced by the regulations, has focused on the real value of the impact.

The product developed by is thus the only one on the market to create a basic scenario for each user, and thus to be able to demonstrate additionality, i.e. the real impact of the change in user behaviour in relation to given impact indicators, starting with CO2 emission reductions.

On the other hand, has developed a real impact management system allowing to pre-finance the expected impact in order to redistribute it as an incentive. This pre-funding mechanism is made possible because the application produces proof of travel which it records in a register. By offering the possibility to associate each proof of trip with a proof of impact additionality, has created one of the very first services capable of justifying emission reductions by financing low emission trips!

Made possible by SmartB technology

SmartB's product is based on a technology platform that allows employers and employees to interact. Two types of actors with totally divergent interests: the employee gets the most money for the least effort, and the company gets the maximum impact by paying the minimum.

To implement a trustworthy environment that makes the cooperation of these actors possible, uses 3 bricks of the SmartB architecture:

  • The "Connect" brick: this is a development environment that makes it possible to implement this management of organisations and users simply and quickly. This ready-to-use opensource brick manages the registration, identification and validation (KYC) of users, associates them with organisations and assigns them complex rights.This brick is essential for the development of impact platforms, as in general the cooperation needed to implement an impact project or service requires interactions between users with different roles in the process and belonging to complex organisational structures.
  • The "Protocol" brick: This is the mechanism for transforming the data collected into evidence of movement. Typically in impact projects, validation operations are carried out by external auditors. Given the volumes of carbon involved in each transaction, a human validation operation is not possible.The use of this brick makes it possible to automate the verification function and entrust it to an algorithm. Thus each proof is verified and signed by an algorithm. This algorithm carries out the impact additionality calculation according to a well-defined protocol. It is itself verified by an expert firm that validates the scientific basis of the protocol, certifies it and thus provides a tangible value to the emissions recorded.
  • The "Factory" brick enables the impact data to be produced. It consists of all the developments that simplify the user experience and enable the production of the impact to be scaled up. In this application, the software bricks have been integrated into a mobile application to perform the automated detection of mobilities and produce the data necessary to produce an impact value in accordance with the protocol.
  • The "impact register" is used to materialise this value. It allows each impact production to be recorded in the form of a transaction credited to its owner. The impacts produced can thus be exchanged between users (the employee and his company).
  • The "Finance" brick allows the impact value produced to be transferred from one user to another by carrying out a transaction on the register. Each euro invested is thus associated with a transaction, which in turn allows the proof of displacement to be found via the protocol, which can be audited with the user's consent.


Using SmartB's technological bricks, has developed a new generation impact service.

It enables hundreds of users within its corporate clients to act consciously, responsibly and change their behaviour by sharing the real value of the impact they produce on society and the environment.

Investors who fund the CO2 savings produced by the application can do so because they get a tangible, quantified and verifiable digital counterpart from the SmartB Registry.


  • The cooperation required to implement an impact project requires the establishment of a multi-stakeholder platform capable of handling a wide variety of different types of actors and roles.
  • Impact assessment requires the implementation of protocols. The scaling up of these protocols can be achieved by automating the validation through verified intermediate algorithms.
  • Producing and valuing impact at scale requires automation of data collection operations associated with traceability of sources and actors' contributions.
  • Impact remuneration is possible when the value of the impact is verifiable and the ownership of the impact produced is clearly established.
