Sustainability Advisory Panel Chair message.

To assist us on our sustainability journey and to ensure we are sufficiently challenged by representatives of our communities we established a Sustainability Advisory Panel.


This is the third year that the Panel has operated as an independently chaired ‘critical friend’ of the bank. Our role is to provide insights into the changing expectations of communities, stakeholders and customers, identifying the changing risks and opportunities in the environment the bank operates in and challenging Westpac to take leadership roles where the organisation can be most effective.

This year our focus has been largely on two areas; climate change and social equity. Climate change because, while it is not particularly physically evident yet, it represents the biggest challenge to the economy and society. Social equity because it is also a fundamental threat to societal cohesion; with an increasing disparity in the ownership of wealth it is difficult to sustain a common vision of a future necessary for progress.

The bank has three areas of contribution to the battle against climate change:

  • Its own footprint and the footprint along its supply chain.
  • Through its lending and investment policies.
  • And as a leader in shaping business opinion.

Managing its lending and investment portfolio to avoid excessive exposure to debts and investments supported by assets whose value will be impacted by the effects of climate change makes good sense from a business perspective. Avoiding lending to future stranded assets also makes sense. Often the bank’s commitments will be long term, especially where there is no one else to take over the position, and these climate related exposures are expected to impact in a relatively short time. These changes in investment and lending criteria need to be signalled to customers early so they can modify their investment plans appropriately. Long term the movement away from climate exposed assets is a necessary change society must make. The Panel ensures Westpac recognises the constructive role it can play.

Similarly, in improving social equity the bank can have three roles:

  • Through its supply chain and purchasing power.
  • As a catalyst investor in social change.
  • As a leader in shaping business and government policy.

The reach and influence for good that a large institution such as Westpac can have should not be underestimated.

In both environmental and social impact Westpac demonstrates its understanding of its role and responsibility to the wider community. The report sets out how Westpac has addressed and plans to address these issues. You will see where Westpac is using its position, its power and its influence to help lead change. More importantly, in many areas, Westpac leads by example and action. Not everything is perfect but good progress is being made and Westpac remains up to the challenges the Panel puts to them.

This year Anne Norman and Phil O’Reilly retired from the Panel and I would like to thank both of them for their contribution over several years as well as thank the other Panel members for their continued interest and support. I also record my appreciation for the support provided to the Panel by Westpac’s sustainability team.
