Signum DataEnvironmental & industrial compliance software
Desktop & browser applications
Regulatory science, in software you can run.
Signum Data builds desktop and browser applications that turn environmental and industrial regulations into calculations you can perform, check and report — air dispersion, noise, Seveso, packaging and carbon accounting.
Every tool implements a published method, so the numbers you submit are numbers a reviewer can reproduce.
AUSTAL 3.3
VDI 3783-8
ISO 9613-2
GHG Protocol
Seveso III
Regulation (EU) 2025/40

The tools
Six applications, from air to packaging
Each one takes the data you already hold and returns the calculation, the assessment and the document you have to file.
DisPolv3.26
Atmospheric dispersionRuns AUSTAL 3.3, the dispersion model recommended by the German Federal Environment Agency, across the whole workflow from emission setup to finished report.
Point, line and area sources
NOAA meteorology, EMEP/EEA 2023 emission factors
Google Earth KML and automated PDF reports
DisPolAirv1.0
Dispersion modellingComputes ground-level pollutant concentrations with two models built into the program — an AERMOD-like Gaussian plume and an AUSTAL 3.3-like Lagrangian particle model — with no external solver.
Stack, line, area and volume sources on a map
Annual AKTerm series: means, maxima, percentiles, exceedances
Word report and AUSTAL 3.3 input export
DisSoniqv1.1
Environmental noiseModels outdoor sound propagation to ISO 9613-2 on a georeferenced canvas, so receiver exposure is evaluated in its real geographic context.
Distance attenuation and barrier effects
Multi-source aggregation, octave-band analysis
A-weighted receiver evaluation on GIS-style maps
CarbonToolv1.1
Carbon accountingTurns everyday activity data — distance, electricity and spend — into a structured greenhouse-gas inventory under the GHG Protocol.
Scopes 1, 2 and 3, across fifteen spend categories
Published EEA and IPCC emission factors
Desktop and web edition, one shared file format
SevesoToolv1.7
Major-accident hazardsChecks a site's dangerous-substance inventory against Directive 2012/18/EU and assembles the documentation an inspection asks for.
Dangerous-substance inventory management
Lower-tier / upper-tier establishment classification
Hazard statements, pictograms and safety reports
PPWR Toolv1.1
Packaging complianceAssesses packaging against Regulation (EU) 2025/40 across twelve obligation areas, returning a status, the article and the deadline for every finding.
Packaging register with material breakdown
0–100 readiness score per item and portfolio
EU Declaration of Conformity on the Annex VIII model
Why these tools
Built to be checked
Compliance software is only useful if someone else can follow what it did. That constraint shapes every one of these applications.
Published methodsAUSTAL 3.3, VDI 3783 Part 8, ISO 9613-2, the GHG Protocol, the Official Journal text. No proprietary black box between your data and the result.
Desktop and browserPortable Windows applications throughout; CarbonTool and PPWR Tool also run entirely in the browser, with the same workflow and the same numbers.
Documents you submitPDF and Word reports, declarations of conformity, Excel registers and KML maps — generated from your own data, ready for customers and authorities.
An academic foundationThe numerical methods behind the tools are the ones set out in Introduction to Numerical Programming (CRC Press), written by Signum Data's founder.
