It is Australia Post policy that all business cases involving an outlay of more than $250,000 must include an assessment of environmental, social, economic and risk impacts (in addition to the financial appraisal). All such business cases also require endorsement by representatives from the Ecologically Sustainable Development Working Party and from the Risk Management Unit before project approval. Post’s procurement policy also features sustainability in general purchasing practices. This policy includes extensive guidelines covering probity, open and effective competition, ethics and fair dealing, and environmental considerations. During the year we changed our sourcing documentation to ensure that our purchasing processes follow sound sustainability principles. Training programs will further reinforce these practices for relevant staff.
