Introducing multi-annual planning and objective setting to monitor the development and impact of environmental improvement over the longer term would enable more effective comparisons and facilitate assessment of environmental outcomes that are difficult to analyse over a single year. Finally, adoption of an explicit environmental enforcement policy by the inspectorate and its units could help establish clear priorities, inform the regulated community about enforcement objectives and provide the basis for longer-term planning and performance assessment. Intent or negligence in cases of endangerment or damage does not need to be proven.
