An environmental audit checks whether a site follows environmental law and its own permits, and whether its pollution controls and waste handling work in practice. In India, the Environment Audit Rules, 2025 now create a system of certified environment auditors for some audits, so scope and auditor choice matter. This guide covers the scope, a step-by-step method and a checklist.
Last reviewed: 17 October 2026. Facts checked. We searched for the Environment Audit Rules, 2025 and opened a Down To Earth report on them. We also searched for the annual environmental statement (Form V). We could not open the rules in the Gazette or any MoEFCC page. Search summaries disagree on whether the rules were notified in late August or early September 2025, and the Down To Earth report gives 29 August 2025 as the date they took effect. We did not verify registration terms, fees or penalties.
What an environmental audit is
It is a systematic, documented review of a site's environmental performance against a set standard. The standard may be law, the site's consent conditions, a company policy or an international standard such as ISO 14001.
There are two main kinds.
- Compliance audit. Are we meeting the law and our permits?
- Management system audit. Do our processes reliably keep us compliant? Our ISO 14001 audit guide covers this one.
The 2025 Environment Audit Rules
According to the Down To Earth report, the Ministry of Environment, Forest and Climate Change notified the Environment Audit Rules, 2025 under the Environment (Protection) Act, 1986. Key points from that report:
- Audits are done by Registered Environment Auditors, who may be individuals or firms certified by a government-appointed Environment Audit Designated Agency.
- Auditors must avoid conflicts of interest, and audit assignments are made through a randomised process.
- The audits check compliance with laws such as the Air Act, the Water Act and forest and wildlife laws, and can include sampling of emissions, effluents and waste.
- They supplement government inspections. They do not replace them.
If your site may fall under these rules, ask the regulator or your consultant which audits must be done by a registered auditor. We have not confirmed which sites are covered.
Scope: what to include
| Area | What to test |
|---|---|
| Permits | Consents and authorisations held, valid, conditions met |
| Air | Stack and ambient emissions against limits, monitoring records |
| Water | Water use, effluent treatment, discharge quality |
| Waste | Segregation, storage, authorised disposal, manifests |
| Chemicals | Storage, labelling, spill response |
| Noise | Readings against limits near the site |
| Records | Returns filed, the annual environmental statement |
| Management | Responsibility, training, corrective actions |
Secondary sources say industries needing consent under the Water or Air Acts, or authorisation for hazardous waste, must submit an environmental statement (Form V) to the State Pollution Control Board by 30 September each year for the financial year ending 31 March. We saw this in a legal compilation, not the rules. Check the current text.
Steps to run the audit
- Define scope and criteria. List the sites, activities, laws and permits in scope.
- Get the register of obligations. Collect every permit condition and legal requirement that applies. Many sites have no such list, and building it is the first finding.
- Review documents. Read consents, past returns, monitoring reports, inspection notices and complaints.
- Walk the site. Look at stacks, treatment plants, waste yards, chemical stores and drains.
- Test the evidence. Check that lab reports come from approved labs, that waste manifests match what left the site and that monitoring dates match the schedule.
- Interview staff. Ask operators what they do when a reading is over limit.
- Grade the findings. Separate legal non-compliance from weak practice.
- Report and fix. Give each finding an owner and date, and recheck after closure.
Checklist
- Current list of laws and permits, with expiry dates
- Consent conditions mapped to evidence of compliance
- Monitoring done at the required frequency and by an approved lab
- Readings above limit have a recorded cause and action
- Effluent treatment plant running when production runs
- Hazardous waste stored, labelled and handed only to authorised handlers
- Waste manifests reconciled to quantities generated
- Environmental statement and other returns filed on time
- Emergency plan for spills and fires, with drills recorded
- Complaints from neighbours or authorities logged and closed
Where a finance team helps
Environmental risk has a money side. Auditors can check provisions for clean-up, penalties disclosed in notes and consistency between environmental data and sustainability reports. See the BRSR and ESG internal audit checklist. For a ready checklist, use our environmental, health and safety audit checklist template.
