Every morning, millions of commutes generate a significant share of greenhouse gas emissions in France. The employer mobility plan requires concerned companies to rethink these trips. But beyond the legal constraint, this device opens up concrete levers to reduce costs, retain employees, and structure a real climate strategy.
Scope 3 and employee mobility: the link that classic plans ignore
Most mobility plans are limited to listing alternatives to individual vehicles. Carpooling, bicycles, public transport: the measures are known. What is less known is the direct connection between these trips and the company’s climate reporting.
Commuting and business travel fall under the scope 3 of the carbon footprint, meaning indirect emissions. According to RSE-Market, a serious employer mobility plan regarding scope 3 starts with a detailed diagnosis that crosses HR data, employee surveys, and local transport data. The goal: to identify the kilometers that can actually be avoided before proposing solutions.
This approach changes the logic. Instead of ticking regulatory boxes, the company sets quantified targets for reducing indirect emissions. To better understand the stakes of the mobility plan in companies, this climate perspective has become the starting point for the most advanced initiatives.
With the gradual entry into force of the CSRD directive, companies subject to extra-financial reporting must document their actions on scope 3. The mobility plan becomes a climate compliance tool, not just an HR document filed away in a drawer.
Mandatory annual negotiation: the legal pivot of the employer mobility plan
You knew that the mobility plan is mandatory for companies with 50 employees or more on the same site, in an urban area of over 100,000 inhabitants. But do you know the mechanism that makes it truly effective?
Since the LOM law, sustainable mobility is among the themes of the mandatory annual negotiation (NAO). Specifically, the employer must address commuting and the use of alternative transport modes during discussions with employee representatives.
If no agreement is reached at the end of this negotiation, the company must then unilaterally develop an employer mobility plan. This mechanism creates real pressure: mobility is no longer an optional topic relegated to the CSR department; it enters formal social dialogue.
What the NAO changes in practice
The negotiation forces data to be put on the table. Average commute times for employees, accessibility of sites by public transport, share of cycling in trips: these elements become discussion topics between management and unions.
This constraint produces a concrete effect. Companies that negotiate often end up with more ambitious measures than those that draft a unilateral plan. The sustainable mobility allowance, for example, is more frequently implemented when it results from a collective agreement.
Sustainable mobility solutions: beyond bicycles and carpooling
The most visible measures (bike fleet, carpooling platform, reimbursement for public transport) form a foundation. The solutions that make a difference go further.
- The mobility credit replaces all or part of a company car with a budget that the employee can use freely: train, occasional rental, cargo bike, scooter. It reduces dependence on individual cars without eliminating flexibility.
- The sustainable mobility allowance allows the employer to pay up to 800 euros per year (amount exempt from charges) to cover commuting costs using alternative modes: personal bike, carpooling as a passenger, public transport outside of a standard subscription.
- Teleworking arrangements, when designed as a mobility lever rather than mere comfort, eliminate trips at the source. Two days of teleworking per week mechanically reduce travel by nearly 40%.
- The installation of charging stations on-site supports the transition to electric vehicles, making the switch to electric concrete for employees who do not have a charging solution at home.
Adapting solutions to the territory
A site in a densely populated urban area does not have the same needs as a warehouse on the outskirts. For the former, enhancing public transport reimbursement or funding bike-sharing subscriptions produces quick results.
For the latter, organized carpooling (with a guaranteed return in case of unforeseen events) or the establishment of dedicated shuttles are often the only realistic levers. An effective mobility plan starts from a field diagnosis, not from a catalog of generic measures.
Common obstacles and mistakes in implementing the mobility plan
The first obstacle is the lack of reliable data. Without a survey of employees about their actual trips, the plan relies on assumptions. Companies that skip the diagnostic step produce compliant documents on paper but without any effect on behaviors.
The second trap: proposing alternatives without addressing practical barriers. Encouraging cycling without showers or secure parking, promoting carpooling without schedule flexibility, recommending public transport when the last bus leaves before the end of service—these inconsistencies kill buy-in.
The third point concerns monitoring. A mobility plan without outcome indicators (modal share, usage rate of the sustainable mobility allowance, evolution of emissions) remains an administrative exercise. Plans that work include an annual review with updated data.
The employer mobility plan gains in scope when it goes beyond the purely regulatory framework. Connected to the climate strategy, rooted in social dialogue through the NAO, fueled by field data and solutions adapted to the local context, it becomes a tool for real transformation of travel. The test of its success is simple: do employees actually change their travel habits?
