Educational guidance on registers and logs — what each records, who maintains it, what it typically contains and how long it is generally kept. Informational only — template examples, not official documents or legal advice; a register documents activity, it does not by itself prove compliance, and employers remain responsible.
What an emissions log is
An emissions log is a record of releases to air from a site’s processes or equipment, together with the readings, checks or monitoring carried out, so the organisation can track what it emits and whether controls are working.
This page is an educational overview with a simplified example. It is not an official template, not jurisdiction-specific and not legal advice — what must be monitored and reported varies by country, sector and any permit in place.
Purpose
- Record emissions to air and the monitoring around them.
- Track whether abatement and controls are working.
- Support any permit conditions or environmental reporting.
- Reveal trends or exceedances that need action.
Who maintains it
- An environmental or process lead keeps it current.
- Monitoring may be done in-house or by a competent contractor.
- Results are reviewed against any permit limits or targets.
- The employer decides ownership and the monitoring regime.
When it is used
- When monitoring or readings are taken on the agreed schedule.
- When an abatement system is checked or maintained.
- When an exceedance or abnormal release is suspected.
- When preparing environmental reports or audits.
Typical fields
- Date, source or stack, and the parameter monitored.
- The reading or result, and the method used.
- Any limit or target it is compared against.
- Abatement status and maintenance carried out.
- Action taken on an exceedance and sign-off.
- Example columns only — adapt to your processes and the applicable law.
Common mistakes
- Recording readings but not comparing them to limits or targets.
- Letting monitoring lapse or skipping inconvenient dates.
- Not acting on or escalating an exceedance.
- Failing to keep abatement maintenance records alongside readings.
Document workflow
An emissions log runs alongside the environmental management chain: monitoring is planned against any permit, results are recorded here, and exceedances feed the environmental-incident register and corrective action completed afterwards. It links to abatement and ventilation maintenance records.
See the related documents below for what is commonly used with and completed after an emissions log entry.
Retention (high level)
Emissions records are generally kept for a period set by the applicable law, any permit and the employer’s obligations. This page does not state a required period — confirm with the applicable law and the official authority.
Completing and sharing as a PDF
Monitoring results are often held in a system and exported to PDF for reports and audits. Exporting to PDF supports the record; it does not satisfy any permit or reporting duty by itself.
Employer checklist
- Monitor on the agreed schedule and record results consistently.
- Compare readings against any permit limit or target.
- Act on and escalate exceedances promptly.
- Keep abatement maintenance records with the readings.
Worker notes
- Follow the monitoring procedure exactly so results are reliable.
- Report abnormal smells, smoke or releases straight away.
- Do not bypass or disable abatement equipment.
Country considerations
What must be monitored, the limits that apply and the reporting required vary by country, sector and permit, and the official authority differs. This page is general and high-level — not a statement of any country’s law and not legal advice.
Confirm current requirements with the official authority for your country and a qualified professional.
Who is responsible
The employer is responsible for controlling emissions, monitoring them and meeting any permit or reporting duty, and for compliance. This page is an educational overview with a template example; it does not make a workplace compliant and does not transfer responsibility.
