Environmental Information Regulations (EIR) vs FOIA

What is EIR and how does it differ from FOIA?

The Environmental Information Regulations 2004 (SI 2004/3391) implement the EU Aarhus Convention and EU Directive 2003/4/EC in England, Wales, and Northern Ireland. Scotland has equivalent provisions under the Environmental Information (Scotland) Regulations 2004. EIR sits alongside FOIA — it is not a subset of it. When your request concerns environmental information, EIR applies instead of FOIA, and it gives you a stronger set of rights in several important ways.

First, EIR’s scope of “public authority” is broader than FOIA’s. It catches any person carrying out functions of public administration — so private water companies, privatised utilities, and contractors managing public functions can be subject to EIR even though they are not listed in FOIA Schedule 1. Second, all exceptions under EIR are subject to a mandatory public interest test. There are no absolute exceptions (except for personal data under reg.13, which defers to data protection law). Third, the “emissions presumption” in reg.12(9) removes several common exceptions for information about actual emissions into the environment.

The 20-working-day deadline (reg.5(2)) mirrors FOIA. Authorities must respond in writing, must state any exception relied upon and the reason for it, and must inform you of your right to make representations (the EIR equivalent of an internal review).

EIR vs FOIA: Key differences at a glance

When EIR matters for journalists

• 1Investigating a private water company's pollution discharge records — EIR reaches water companies; FOIA does not.
• 2Requesting internal reports on a council's air quality monitoring — the reports are "environmental information" under reg.2(1)(d).
• 3Seeking cost-benefit analyses behind a planning decision for a major infrastructure project.
• 4Asking a privatised railway company about soil contamination on its land — a public administration function.
• 5Requesting emissions data from a waste management contractor that runs a public-sector contract.
• 6Obtaining flood-risk modelling data held by the Environment Agency or Natural Resources Wales.
• 7Asking for pesticide application records near a school — falls within reg.2(1)(f) (human health/safety).

Red flags in an EIR refusal

• ⚠The authority cites a FOIA exemption number (e.g. s.43) rather than a reg.12 EIR exception — they may have applied the wrong regime.
• ⚠The authority claims a reg.12 exception is "absolute" and refuses to apply the public interest test — that is always wrong under EIR.
• ⚠A commercial interest exception is cited for information about actual emissions (reg.12(9) bars this).
• ⚠The authority refuses to let you inspect documents in situ and demands a copying fee before disclosure — EIR requires in-situ inspection to be free.
• ⚠A private company claims it is not subject to EIR without explaining why its functions are not public administration.
• ⚠The authority fails to state which specific reg.12 exception applies — a refusal must cite the specific exception and explain the reason.
• ⚠The response arrives after 20 working days without explanation or extension notice.

EIR request checklist

• Confirmed that my request concerns environmental information (state of elements, factors, measures, reports, cost-benefit, or human health/safety).
• Checked whether the body I am requesting from carries out public administrative functions — even if it is a private company.
• Noted the date the request was received so I can track the 20-working-day deadline.
• Did not limit my request to "FOIA only" — I have left the regime open so the authority applies EIR if required.
• If refused: identified the specific reg.12 exception cited and whether the authority applied the public interest test.
• If the refusal relates to emissions information: checked reg.12(9) to see if the exception is barred.
• Drafted an internal review request if refused — citing the specific exception and why the public interest favours disclosure.
• If a private body: prepared to argue that it carries out functions of public administration under reg.2(2).

Common mistakes

• ›Filing under FOIA when EIR applies — you lose the stronger public interest test and the emissions presumption.
• ›Assuming private companies can never be subject to access rights — EIR catches far more organisations than FOIA.
• ›Accepting a commercial-confidentiality refusal for emissions data without checking reg.12(9).
• ›Paying copying fees without asking whether you are entitled to inspect the documents in situ for free first.
• ›Failing to challenge a blanket refusal that cites no specific exception — EIR requires the specific reg.12 exception to be named.
• ›Not applying the public interest test angle in your internal review — remind the authority that EIR has a presumption in favour of disclosure.
• ›Forgetting that Scotland, Wales, and Northern Ireland have separate (though substantively similar) EIR provisions.
