Controversial radio presenter Alan Jones has been found in breach of the commercial radio standards over his reporting on environmental issues.

The communications watchdog has ruled that Sydney radio station 2GB breached the commercial radio codes of practice for material that aired on Jones' breakfast program early last year on two counts: accuracy and failing to allow other viewpoints to be heard.

Jones is the first person to be found in breach of the "significant viewpoints" rule, which requires that there is a reasonable opportunity for other views on an issue to be heard.

Jones' comments were highly critical of the operation of native vegetation laws and their administration by the former New South Wales Department of Environment and Climate Change.
