Software · permitted sites, cited
Environmental monitoring software captures and checks the monitoring a permitted site must carry out, from periodic stack tests to continuous emission monitors, and turns it into permit returns and inventory submissions.
The permit, not the software, sets what is measured and how; this page sets out the standards a tool must meet, then lists 11 EHS platforms in their own words.
What the software does
A permitted site monitors because its permit tells it to, so the software’s first job is to hold the permit conditions and the monitoring they require.
The Environment Agency says permits set the measurement methodology, monitoring frequency and reporting procedures, and that monitoring should use recognised standards wherever possible.
This is a different product from a corporate carbon inventory, covered on carbon emissions tracking software; the regime itself is explained on environmental permitting and air emissions.
CEMS readings through the DAHS, and periodic test reports from MCERTS contractors.
Apply the EN 14181 calibration and flag invalid or missing periods.
Check results against the permit’s emission limit values.
Permit returns, Pollution Inventory submissions, UK ETS data.
Keep certificates, calibrations and corrective actions for inspection.
Periodic or continuous
The Environment Agency recognises two approaches: periodic measurement at intervals, and continuous emission monitoring systems, which measure automatically all the time.
MCERTS is the Agency’s certification scheme for instruments, monitoring and analyses, and stack testing under it needs EN ISO/IEC 17025 and MCERTS-certified personnel.
For continuous monitors, the Agency’s standards page names EN 14181 for certification, calibration and ongoing quality assurance, and EN 17255-4 for the data acquisition and handling system.
So the software question is whether a platform takes DAHS output as it is, keeps the calibration status beside each reading, and flags invalid periods rather than filling them.
Predictive emissions monitoring systems, which model emissions from process data, are allowed as an alternative and follow CEN TS 17198, according to the same page.
For low-risk medium combustion plant, the Agency’s guidance allows CEMS instead of periodic measurement only where the CEMS meets MCERTS.
The four Agency documents are gathered in the monitoring stack emissions collection.

Medium combustion plant
A medium combustion plant is one with a rated thermal input of 1 megawatt or more but less than 50, under Schedule 25A.
An existing plant greater than 5 MWth needed its permit by 1 January 2024 and has had to meet its emission limit values since 1 January 2025.
An existing plant from 1 to 5 MWth needs its permit by 1 January 2029, and the limit values apply from 1 January 2030.
The calculator beside this gives both dates for your plant, because the commonest error is quoting the permit date for the limit values, or the other way round.
Existing medium combustion plant · your two dates
| Duty | From |
|---|---|
| Hold an environmental permit | 1 January 2029 |
| Meet the emission limit values | 1 January 2030 |
An existing plant from 1 MWth up to and including 5 MWth.

Returns and inventories
Regulation 61 lets the regulator require information by notice, and treats compiling an inventory of emissions as one of its functions.
So the Pollution Inventory reaches a site because it received a notice, typically as a Part A(1) permit holder, not because it holds any permit.
Scotland and Northern Ireland run separate inventories under their own laws, so a group with sites across the UK reports to more than one system.
A UK ETS installation also submits a verified emissions report for each calendar year by 31 March, and the excess emissions penalty sits in article 52 of the scheme order.

Monitoring requirements are permit conditions, so a tool that flags an exceedance or a gap the day it happens gives the operator the most time to act and record what it did.

Frequently asked
Software that captures, checks and reports the monitoring a permitted site must carry out: stack emissions from periodic tests or continuous monitors, discharges, waste and the other conditions in its permit.
It feeds permit returns, Pollution Inventory submissions and, for some sites, the UK ETS emissions report.
The permit.
The Environment Agency says permit applications must include monitoring proposals and permits set the measurement method, the monitoring frequency and the reporting procedures.
In England and Wales this sits under the Environmental Permitting Regulations 2016.
The Environment Agency’s Monitoring Certification Scheme, which it describes as being for instruments, monitoring and analyses.
For stack emissions, organisations meeting MCERTS need EN ISO/IEC 17025 and MCERTS-certified personnel, among other requirements.
Periodic monitoring takes measurements at intervals, such as every three months, with samples analysed on or off site.
Continuous emission monitoring systems measure automatically and continuously, in the stack or by extraction to an instrument nearby.
EN 14181, which the Environment Agency says covers the certification, calibration and ongoing quality assurance of CEMS for every determinand.
The data acquisition and handling system follows EN 17255-4.
A combustion plant with a rated thermal input of 1 megawatt or more but less than 50 megawatts, under Schedule 25A of the Environmental Permitting Regulations 2016.
By 1 January 2024 if it is greater than 5 MWth, and by 1 January 2029 if it is 1 to 5 MWth.
The emission limit values apply a year later in each case: 1 January 2025 and 1 January 2030.
No. Its legal basis is a notice: regulation 61 lets the regulator require information by notice, and compiling an inventory of emissions is treated as one of its functions.
In practice the Environment Agency issues regulation 61(1) notices to Part A(1) permit holders and certain other sites.
No. Scotland runs the Scottish Pollutant Release Inventory under its own regulations, and Northern Ireland its own inventory.
All feed the UK pollutant register, but the duties are separate.
The Environment Agency scores permit breaches over the calendar year and places each site in a band from A to F. The band multiplies the next year’s subsistence charge, from 95% for band A to 300% for band F.
It must monitor under its monitoring plan and submit a verified emissions report for each calendar year by 31 March, and ultra-small emitters still monitor.
Software helps hold the data and the evidence the verifier will ask for.
No. This page is built from the Environmental Permitting Regulations 2016 and Environment Agency guidance, and the vendor list quotes only what each vendor says about itself.
