However, in the case of more complex requests for particular data on the environment (e.g. on transboundary watersheds) requiring the collection of specific data, the Ministry may not have the capacity to do so and may not be in a position to fulfil the request. Requests to NAMEM for multiyear data on air quality' can be responded to upon payment (a rate is applied per digit of data). If the request asks for information about a person or a company, such information is considered confidential and is not provided to the requester.
