The mobility survey and the indicator dashboard

The survey is the foundation of the plan: the diagnosis, the measures, the objectives and the Scope 3 Category 7 calculation all rest on it.

Two waves, not one

If your site has a seasonal peak, run the survey twice: once in the ordinary season and once in campaign. The modal split is not the same, and a plan built on ordinary-season data will not describe the period the law requires you to address.

Peak data has a one-year replacement cost

If your campaign runs in September and you miss it, the next chance to measure the real peak is September the following year. With the deadline on 5 December 2026, that is the difference between a data-based plan and one built on estimates.

The minimum set of questions

Anonymous, with results aggregated by gender and age — art. 27.2 will make those aggregates public.

Workplace, shift and contract type (permanent / permanent-seasonal / seasonal)
Postcode or municipality of origin — not the home address
Main mode and combined modes; if by car, number of occupants
Distance and journey time; departure and arrival times
Access to a vehicle and a driving licence — key to the exclusion risk of seasonal staff
Estimated monthly spend on commuting
Willingness to change mode, and under what condition
Incidents or perceived risk situations on the journey

Once this minimum is covered and you want a diagnosis that explains the why — barriers, reasons and willingness to change — the bank of optional questions for the diagnosis collects the advanced ones, grouped by the plan decision each unlocks.

Questions 5 and 8 are the most often omitted and carry the most weight: 5 tells you whether a group physically can comply with a measure, 8 feeds the mandatory road safety block.

Never collect home addresses

Postcode or municipality is enough for distance and route analysis, and it keeps you clear of both the publicity obligation in art. 27.2 and the data minimisation principle.

Participation

Target 40% or above and the diagnosis is defensible. Between 25% and 40% it is usable, but state the limitation and how you extrapolated. Below 25%, expect it to be challenged in negotiation.

Seasonal staff always respond less. Two things move the needle: running the survey at induction rather than by email, and in the languages your seasonal workforce actually speaks.

The minimum indicator dashboard

EDIM will register “the most relevant parameters and indicators” (art. 26.8), so use numbered indicators, each with a baseline, target, owner and source. Nine is a workable minimum:

Modal split per site and season (% of journeys by mode)
Average private vehicle occupancy
Shuttle users vs. seats offered
People registered and matched in carpooling
tCO₂e from employee commuting, total and per person-year
In itinere and business-travel accidents: count, rate per 100 people, days lost
People trained in road safety over seasonal inductions
Charging points installed and energy delivered
Plan execution rate: measures implemented / measures committed

An indicator without a baseline cannot be reported in the biennial follow-up, where the second compliance obligation sits.

Doing this in Dcycle

Customise mobility surveys — build the questionnaire and add the questions above
Manage employee survey periods — run the two waves as separate periods, which keeps ordinary season and campaign separable
Upload commuting data — if you already hold the data
Estimate employee commuting — where survey coverage is too low

Running the waves as two periods is what lets you report a modal split per season in the plan and a Category 7 figure split the same way.
