On a day-to-day basis we interact with state EPAs and other environmental departments to address issues and provide guidance and feedback.

On a project basis, we have been involved in a number of significant projects that have shaped environmental policy in Australia.

Key Projects include:

• Development of the National Pollutant Inventory (NPI)
• Policy advice to the National Environment Protection Council (NEPC) for the development of the National Environment Protection Measure – Air (NEPM Air).
• Development of the technical basis underpinning the policy for installation of vapour phase reduction technology at petrol stations within the metropolitan Sydney region and Greater Metropolitan Region of NSW for NSW DECC. 
• Preparation of the comparative fuels study involving technical analysis of emissions and toxicity of pollutants underpinning the Commonwealth’s policies on alternative fuels. 
• Policy advice to the Queensland EPA sustainability section on the effect of E10 fuel on air quality in South East Queensland. 
• Development of technical policy guidance documents for the development of point source inventories, diffuse source inventories and the use of Pollutant Release and Transfer Register (PRTR) data – for the Organisation of Economic Co-operation & Development (OECD, Brussels).

As PAE we played a key role in the development of the Air Emissions Inventory for the Greater Metropolitan Region in NSW, which is a primary tool underpinning environmental policymaking with respect to air quality in NSW.

Our principals are and have been involved in committees and expert panels run by policy development authorities. Examples include the National Environment Protection Measure (NEPM) Peer Review Committee and NSW Department of Health: Environmental Health Expert Panel.
