The Clean Air Society of Australia and New Zealand (CASANZ) is a non-governmental and non-profit professional association that has been active for over 40 years, currently with a membership base of over 600 members predominately from within Australia and New Zealand, but also extended to other countries. Its primary focus is the study of environmental science and management with particular emphasis on air quality, climate change and related topics.[1]

CASANZ provides lectures, exhibitions, public meetings and conferences as a forum to expand knowledge of environmental matters, especially air quality, including causes, effects, measurement, legislative aspects and control of pollution. It also publishes monthly newsletters as well as a quarterly journal entitled Air Quality and Climate Change.

The operation and governing of CASANZ


CASANZ operates through autonomous branches which determine their own programs of activities, technical meetings, seminars, workshops, conferences, training courses, etc.

CASANZ is governed by its Council, consisting of an elected Executive, branch representatives and representatives nominated for special purposes. The Executive manages the day to day activities of CASANZ and directs the work of the part-time Executive Officer and Administrative Officer.

Special Interest Groups (SIGS)


As of July 2014, CASANZ had eight Special Interest Groups (commonly referred to as SIGs), each of which is briefly discussed in the following subsections.[2]

Modeling Special Interest Group


The objective of the Modeling Special Interest Group is to bring together CASANZ members who have an interest in the development and/or application of atmospheric dispersion modeling[3] [4] in order to exchange ideas, identify common problems, inform members of new developments, and establish, as appropriate, a 'ModSIG view' on issues of relevance.

Dispersion modeling is becoming more and more a part of licensing emissions to the atmosphere and there is growing awareness of the role that air quality modeling can play in areas such as air resource management, risk assessment and land-use planning.[5]

Odor Special Interest Group


The Odor Special Interest Group is an important forum for the exchange of information, and in encouraging improved practices in odor measurement, modeling, assessment, control, management and monitoring.[6]

Indoor Air Special Interest Group


The Indoor Air Special Interest Group promotes discussion and debate on the state of knowledge and the quality of indoor air, and on related environmental health concerns. The group encourages research, education, community awareness and management of issues related to this topic.[7]

Greenhouse Special Interest Group


The purpose of the Greenhouse Special Interest Group is threefold:[8]

  • To identify the research and development work being done at national and international levels on the science of greenhouse and global climate modeling as well as the developments being undertaken to assess and quantify the impact of climate change.
  • To inform CASANZ members and the broader community on greenhouse gas emissions, emission scenarios, regional contributions and economic and technological developments.
  • To provide response to government policies and initiatives in the area of energy reform and greenhouse abatement so as to stimulate debate amongst members and the broader community.

Measurement Special Interest Group


The primary objective of the Measurement Special Interest Group is to ensure that atmospheric pollutants in the ambient air and industrial source emissions are measured utilizing methods that are fit for that purpose.

The objective is to be achieved by: conducting workshops, developing decision trees to assist in selecting appropriate air pollution measurement test methods and developing source emission and ambient air quality test methods in cooperation with Standards Australia and Standards New Zealand.[9]

Transport Special Interest Group


The Transport Emissions and Fuel Consumption Modeling Special Interest Group (or simply the Transport Special Interest Group) focuses on the quantification and modeling of air pollutant and greenhouse gas impacts from all forms of transport and their support equipment. The Transport Special Interest Group is intended to be a platform for information sharing, discussion of emerging issues and coordination.[10]

Risk Assessment Interest Group


The Risk Assessment Interest Group exists to be knowledgeable and supportive of governmental policy developments involving risk assessment, such as:[11]

  • The National Air Quality Standards (Air NEPM) which were developed with the help of risk assessment.
  • Variations to the State of Victoria's Environment Protection Policy for Air Quality Management to incorporate formalized risk assessments.
  • The National Environmental Health Strategy, which includes risk assessment as a basis for decision making.
  • The Australian Standard for Risk Management (AS4360-1999).
  • The proposal to develop a coordinated national strategy for air toxics.

Air Policy Special Interest Group


The purpose of the Air Policy Special Interest Group is to bring together CASANZ members interested in advancing air policy development and contributing to responsible air quality related risk communication by:[12]

  • Exchanging ideas, and informing members of new air policy related developments and air quality issues of significant public concern.
  • Coordinating and communicating science-based inputs for air policy, legislative and regulatory development processes.
  • Collating and communicating science-based information to communities and decision makers on pressing air quality related issues, including official inquiries.
