While environmental sustainability has grown in importance to governments and the community, the purpose of this paper is to examine the environmental sustainability activities of A-REITs over the period of the global financial crisis. Using a content analysis methodology similar to Newell, annual reports and home websites for 24 of the largest A-REITs (which have also been a constituent of the ASX 300 index) are analysed to determine the extent of their sustainable investment activities. The Green Building Council of Australia and NABERS websites are also explored. Given the increasing focus on sustainable commercial property, the study finds that A-REIT investment into these properties has been rather conservative and slow. There are, however, some A-REITs that have tried to lead in the field even during the period of the global financial crisis.Relatively solid and stable returns on equity and assets appear to be achieved by such A-REITs in the years during and following this crisis.
