The Environment Protection and Biodiversity Conservation Act 1999 requires CASA to report on how its outcome and activities accord with the principles of ecologically sustainable development.
Environmental management system
CASA’s environmental management system is designed to improve our environmental performance and reduce the environmental impact of our operations.
Our environmental sustainability policy is a key element of the environmental management system. The policy formalises CASA’s commitment to environmental protection and provides a framework for achieving continuous improvement in environmental performance.
Measures taken to minimise the impact of activities on the environment
Strategies are in place to reduce the environmental impact of our operations. Objectives, targets and action plans are set out clearly, and responsibilities and timeframes have been established.
Environmental initiatives undertaken during the year included:
- conducting waste audits at CASA’s Brisbane and Canberra offices, where there have been noticeable improvements in diversion of waste from landfill
- maintaining accreditation in the Australian Capital Territory Government’s business waste recycling program
- increasing the number of vehicles under 1,800cc and/or hybrid from 10 to 16 vehicles
- promoting the use of video conferencing as an alternative to air travel, and increasing video conferencing facilities
- achieving 4.5 star or better base building National Australian Built Environment Rating System (NABERS) ratings for the leased office accommodation that we occupy in Brisbane, Canberra, Melbourne and Sydney
- continuing to collect soft plastics for recycling in the Canberra office.
CASA achieved a number of improvements in relation to environmental performance indicators during 2019–20, as shown in Table 14.
CASA was not involved in any actions likely to have a significant impact on matters of national environmental significance on Commonwealth land.

Office energy use
CASA has in place an energy management plan aimed at minimising its use of energy in office buildings. When choosing and fitting out new office accommodation, we attempt to minimise our environmental footprint by including energy-efficient features and specifying energy-efficient lighting systems and fittings.
Motor vehicle fleet
CASA has a policy of selecting motor vehicles that are fit for purpose and provide the best value for money. Where operationally practical, CASA leases small, fuel-efficient vehicles.
During 2019–20, we operated a vehicle fleet consisting of 34 vehicles, of which 47 per cent had engine capacities under 1,800 cubic centimetres or were hybrid vehicles. Since 2010, the CASA fleet has reduced in size by 16 vehicles.
During 2020–21, CASA will continue to consider hybrid vehicles that meet its operational requirements.
Waste management and resource efficiency
All of CASA’s offices provide a range of recycling opportunities. Through improved recycling signage and awareness campaigns, CASA is increasing the amount of waste diverted from landfill to recycling.
Specific stationery recycling stores operate in Brisbane and Canberra, allowing staff to place surplus stationery in a central location for use by others. The re-use of stationery is encouraged at all CASA sites.
In Canberra, CASA has remained accredited under the Australian Capital Territory Government’s recycling program (Actsmart) since the program’s inception 11 years ago.
All of CASA’s office paper contains more than 50 per cent recycled content or is certified as carbon neutral.
