An example
This could be your situation.
Take one company as an example: three sites, three spreadsheets, no shared answer.
Nobody can consolidate.
Nordhavn Industries, 2,400 people in Hamburg, Lyon and Porto. A client asks where the group stands. Each site answers in its own spreadsheet, with its own scales.
Three weeks, a single base.
One Directive 2008/50/EC of 21 May 2008 on ambient air quality and cleaner air for Europe assessment launched across all three sites at once, from the managers’ interview notes. The framework was already written, its 10 themes and levels L1 to L5 too.
Two costs avoided before being committed.
A score of 53 out of 100, with the gap concentrated on three themes. The AI companion spotted that two actions duplicated those of another audit. The committee report took one sentence to request.
What it saved them
- 3sites measured on the same base, instead of three questionnaires to reconcile
- 2duplicate actions caught before the spend
- 1committee report, with no manual rework
These figures are an example. They could be yours.
The standard imposes processes. Datamensio says where you stand.
01
The framework is already written
Themes, questions and levels L1 to L5, all written. You do not start from an empty spreadsheet.
02
The score lands the same day
Online, by self-assessment link or in interview. Theme by theme, comparable over time.
03
The gap becomes a costed plan
Every step up carries its action. The AI prioritises on expected effect, not on the order of the standard.
04
Progress can be demonstrated
Campaign after campaign, against your target and against your own past. That is what your board asks for.
The maturity scale
One level, the next, and the action that links the two.
This mechanism, a level, a level above it, and the action connecting the two, is what turns an exceedance finding into a reduction trajectory.
Are diffuse dust emissions quantified and controlled through measures whose effectiveness is verified?
- N1
No quantification of diffuse emissions. Action is limited to watering triggered at the shift supervisor’s discretion.
- N2
The main sources are listed in a document. Controls exist (watering, enclosures) but their application depends on the day’s conditions and is not recorded.
- N3
Sources are quantified, a control plan pairs each one with a defined measure that is applied and logged. Fallout results are tracked by point.
- N4
The effectiveness of measures is verified by comparing fallout measurements with boundary concentrations, with documented adjustment of the control plan.
- N5
The control plan is steered by consolidated indicators, revised according to weather, operational changes and modelling results, with multi-year reduction targets being met.
Action to move from L2 to L3
Quantify every listed diffuse source from tonnages handled and distances travelled, pair each one with a control measure that has a frequency and an owner, and log its implementation in the shift report, checked at the monthly operations review.

What this framework covers
Directive 2008/50/EC consolidates European ambient air legislation. It sets limit values for PM10 particulates, nitrogen dioxide, sulphur dioxide, lead, benzene and carbon monoxide, a target value followed by an exposure reduction obligation for PM2.5, and information and alert thresholds. It requires member states to divide their territory into zones and agglomerations, organise monitoring there using reference methods, and adopt an air quality plan whenever a limit value is exceeded. An operation located in a zone with an exceedance is directly caught by that plan.
In practice, oversight runs into simple questions that are rarely settled. Are diffuse emissions from haul roads, stockpiles and crushing areas quantified, or just hosed down whenever the wind picks up? Are the boundary monitoring stations positioned according to defensible criteria, and is their data validated before being submitted? Do occasional exceedances trigger root cause analysis, or just a line in the annual report? Across a multi-site group, comparing quarries is often impossible for lack of a common protocol.
Two developments are reshaping the picture. Directive (EU) 2024/2881, which recasts 2008/50/EC and must be transposed by December 2026, brings limit values closer to World Health Organisation recommendations and strengthens both compensation rights and monitoring requirements. Beyond that, confusion between ambient air and stack emissions remains common: 2008/50/EC concerns the air people breathe, whereas stack emission values fall under environmental permitting and best available techniques. The two meet in the demonstration of impact, not in the same documents.
A compliance audit settles a binary question: the limit value is met or exceeded, the report was submitted or it wasn’t. A maturity assessment asks something else. What level of control has been reached in monitoring, dispersion modelling, diffuse emission reduction, relations with local residents and with the authority. Then which precise action moves each theme up a level. That is what turns an annual finding into a transformation programme tracked over time.
The framework is ready to use in Datamensio and remains yours. The AI adjusts themes, questions and levels to your context, aggregates quarry, underground mine or processing plant, or builds a variant from your operating permits and monitoring reports. The AI models used can be selected, including from European providers.

Frequently asked questions
Can Directive 2008/50/EC be certified?
No. It is a regulatory text transposed into national law, checked by the environmental permitting inspectorate rather than by a certification body. The assessment measures your level of control and prepares you for inspection, it issues no certificate.
How does this differ from a regulatory compliance audit?
An audit checks that limit values and permit conditions are met at a given date, and concludes with a gap or a pass. The assessment places each theme on a maturity scale and identifies the action that moves it up a level. The assessment prepares the audit, the audit validates.
Does the directive apply directly to my extractive site?
The directive is addressed to member states, which organise monitoring and adopt air quality plans. Operations are caught by those plans and by the conditions of their operating permit, particularly on dust and nitrogen oxides. The framework assesses precisely that chain, from the European text through to on-the-ground practice.
How do we account for the 2024 recast?
Directive (EU) 2024/2881 replaces 2008/50/EC and tightens limit values, with transposition expected by December 2026. The assessment lets you set a target aligned with the new values and measure the gap now, site by site.
How long does the assessment take?
The short version can be completed in a single working session with the site’s environment manager. The full version, run collaboratively with operations, metrology and the laboratory, takes one to two weeks, with most of the time spent gathering monitoring data.
Can the framework be adapted to our site types?
Yes. You can edit the questions, levels and themes, or start from a blank framework. The AI also builds a variant by site type (hard rock quarry, gravel pit, underground mine, processing plant) from your permits and reports.
Can several sites be compared against each other?
Yes. Assessments run on the same framework can be compared by business unit and over time. The AI groups common gaps into a consolidated roadmap, avoiding a separate action plan per site for identical issues.
Where is the data hosted?
In France, with OVH, backed up with Scaleway. No transfer outside the European Union. The AI models used can be selected, including from European providers.
