What is Access to Information on the Environment (AIE)

Members of the public have a right to know and access information about the environment around them. It helps people to take part in environmental decision-making in an informed way.

AIE regulations

Members of the public have access to such information through the AIE regulations. Under these regulations, environmental information held by a public authority should be provided to any person who requests it.

Procedures apply to this process and access to information may be refused in certain circumstances. There is an appeals process in case a person is unhappy with a decision on their request.

For the full AIE regulations visit the government website Access to Information on the Environment (AIE).

If your request for environmental information is refused wholly or partially, or you consider that your request was not properly dealt with in accordance with the provisions of the AIE Regulations, you may, not later than one month following receipt of the decision, request the CRU to carry out an internal review of the decision.

No fee will be charged for the internal review process.

This fee may be waived, for example, where environmental information has not been provided within the specified time period.
