Sustainable Commuting Plan (PMST)

December 5, 2026, is the deadline that many Spanish companies and public agencies now have to develop and approve their Sustainable Commuting Plans.

Organizations with workplaces employing more than 200 people, or more than 100 per shift, should be aware that the PMST is no longer optional but has become a legal obligation subject to deadlines, collective bargaining, and penalties for noncompliance. This requirement also applies to public administrations, such as city councils, provincial councils, etc.; it is not exclusive to the private sector.

What has changed, and what is the new deadline?

Law 9/2025, dated December 3, on Sustainable Mobility, already required companies and public-sector entities with workplaces employing more than 200 workers (or more than 100 per shift), with a deadline of December 5, 2027. The Royal Decree-Law 7/2026, dated March 20, has cut that deadline in half: the new deadline is December 5, 2026.

The scope of application remains unchanged; the companies subject to the requirements are the same, and the threshold continues to be calculated per workplace, not based on total headcount. What has changed is that there is half as much time to negotiate and implement it, and the Royal Decree-Law adds additional pressure: companies receiving direct public aid must repay it if they fail to comply, and noncompliance may affect their eligibility for grants or participation in public tenders.

What Should a Sustainable Commuting Plan Include?

The regulation does not leave the content of the Sustainable Commute Plan open to interpretation by individual companies. The plan must be negotiated with the workers’ legal representatives and must include, among other things, measures such as:

• Active transportation (on foot or by bicycle)

• Public Transportation

• Shared or collaborative solutions (carpooling)

• Telework

• Road Safety

• Etc.

And there is one nuance that often goes unnoticed: if the municipality where the workplace is located has its own Sustainable Urban Mobility Plan (SUMP), the company’s plan must take it into account and align with it. This means that a well-designed PMST is not developed in isolation from the city, but rather in harmony with it. Its implementation brings benefits to the organization, to employees, and to society as a whole.

Why is it better to start now rather than in November?

A Sustainable Commuting Plan is not a document that can be drafted in a couple of weeks. Before drafting a single measure, it is essential to understand how the workforce actually commutes: where they come from, what modes of transportation they use, where the bottlenecks are, and what environmental impact their daily commute has. Only with that assessment does it make sense to design measures that the workers’ legal representatives will negotiate and accept—and that will also stand up to a potential inspection.

On top of that, there is the time required for the collective bargaining process itself, which does not happen overnight.

CPS’s Experience in Mobility and Land-Use Planning

At CPS, we have been working on mobility, transportation, and civil engineering projects for more than 35 years, with a presence in Spain and in markets such as Peru, Mexico, Colombia, and Sweden. Our team has participated in more than 30 sustainable urban mobility plans and works continuously with government agencies and companies on projects related to active mobility, public transportation, and traffic management.

At the Commercial Port of Valencia, the Port Authority commissioned us to develop the Sustainable Commuting Plan for 3,138 workers, covering a 10-kilometer commuting catchment area . Here , the added challenge was the port’s own operations: coordinating people’s mobility without interfering with freight traffic or the port’s daily operations.

At the Elche Business Park , we are working with the Valencian Regional Government to design a Sustainable Mobility Plan for an entire industrial area: 700 companies, 12,000 workers, and more than 6,000 parking spaces spread throughout the area.

Two different projects, two different clients, but the same approach: first understand how each environment actually works, and then design a plan that works in practice, not just on paper.

How can we help you?

At CPS, we can guide you through the entire process: preliminary meetings to define the scope of the work, mobility assessments, designing measures, coordinating with existing municipal plans, and providing support during negotiations with employee representatives. We can also conduct presentations or participatory workshops.
