Climate change and environmental issues

Our commitment to action on climate change

Our ambition to become a net-zero, climate resilient bank

Climate change is a significant issue which is already impacting our business, customers and community. We seek to play our part in addressing these impacts, through our ambition to become a net-zero, climate resilient bank.

In July 2022, we joined the Net-Zero Banking Alliance (NZBA) and continued our work on reducing our operational and financed emissions and aligning our lending portfolios with net-zero financed emissions by 2050, consistent with a pathway to limit global warming to 1.5°C above pre-industrial levels by 2100.

We were a founding member of the UN's Environment Programme Finance Initiative, signed the Equator Principles in 2003 and were the first Australian bank to release a Climate Change Position Statement in 2008.

Our climate strategy is structured along three action areas that focus on our own operations, supporting customers and advocating for positive change.


We aim to deliver on our strategy through the actions and initiatives set out in our Climate Change Position Statement and Action Plan (PDF 1MB). Unless specified, we aim to implement the actions in our Action Plan by 30 September 2025. Other targets refer to Westpac Group’s financial year, e.g. 2030 targets to be achieved by 30 September 2030.


At our 2023 Annual General Meeting, over 90% of shareholders voted to support Westpac’s Climate Change Position Statement and Action Plan.

Our principles

  1. A science-based transition to a net-zero emissions economy is required by 2050
  2. Addressing climate change should reduce risks and create opportunities for our business and customers
  3. Transition should be technology-driven, inclusive and safeguard our natural environment
  4. Collective action is vital
  5. Our approach should be transparent with thorough disclosures

Key targets and objectives¹


Net-zero, climate resilient operations

  • Scope 1 and 2 absolute emissions reduction target of 64% by 2025 and 76% by 2030 from a 2021 baseline
    • Source the equivalent of 100% global electricity demand from renewable sources by 2025²
    • Transition our Australian and New Zealand fleet vehicles to 100% electric or plug-in hybrids by 2030³
  • Scope 3 upstream absolute emissions reduction target of 50% by 2030 from a 2021 baseline
  • Develop our approach to assessing and managing physical climate risk to our operational sites.

Supporting customers’ transition to net-zero and to build their climate resilience

  • Align our lending portfolio with net-zero by 2050 consistent with a 1.5°C4 pathway in line with our NZBA commitment
  • NZBA 2030 sector lending targets in carbon intensive sectors, as detailed in the NZBA Guidelines (NZBA priority sectors) (For further information, refer to our Action Plan (PDF 1MB))
  • Provide $55bn of lending and $40bn of bond facilitation activities by 2030 that are aligned with our Sustainable Finance Framework (PDF 4MB)
  • Seek to help customers understand and better respond to the impacts of climate change to support adaptation and resilience.

Collaborate for impact on initiatives towards net-zero and climate resilience

Contribute to government and industry initiatives and engage on matters of climate policy.

We have developed positions on oil and gas, coal mining and power generation (summarised in our Climate Change Position Statement and Action Plan (PDF 1MB). These positions operate alongside our NZBA 2030 sector lending targets.


¹ For details on our key targets and objectives refer to our Action Plan (PDF 1MB).

² The challenges of developing local renewable energy infrastructure and the lack of renewable energy certificate markets in some of the international markets Westpac operates in are a recognised risk to this target. We are monitoring this risk and actively seeking to solve for these challenges as we work towards meeting our commitment.

³ May include hybrid or plug-in hybrid electric vehicles (PHEVs) to serve customers in locations where electric vehicle charging infrastructure is not widely available. Supply chain challenges and roll-out of charging infrastructure at a national scale are risks to this target at the time of setting. This target will be reviewed in 2025 to consider the status of these risks.

 ⁴ A pathway to net-zero by mid-century, or sooner, including CO₂ emissions reaching net-zero at the latest by 2050, consistent with a maximum temperature rise of 1.5°C above pre-industrial levels by 2100.

Our targets

In line with our NZBA commitment, we have set 2030 financed emissions targets.


Upstream oil and gas1

Target: 23% reduction of scope 1, 2 and 3 absolute financed emissions by 2030 from a 2021 baseline.

¹ Includes exploration, extraction and drilling companies, all activities of integrated oil and gas companies (IOCs), tolling and stand-alone refineries and LNG producers. Does not include downstream retail and distribution, pipeline infrastructure, storage and transport, nor trading entities.


We continue to integrate and operationalise our targets into our processes and lending decisions.

The information on this page contains ‘forward-looking statements’ and statements of expectation reflecting Westpac’s current views on future events. They are subject to change without notice and certain risks, uncertainties and assumptions which are, in many instances, beyond its control.

1 As at 30 September 2023.
2 Based on IJGlobal and Westpac Research Data for the period 1 October 2018 to 30 September 2023.
3 On track to achieve 100% renewables outcome for our direct operations. 95% of this supply is expected to be sourced from within the markets the electricity is consumed. We will continue to identify opportunities to lift local sourcing to 100%, to include for our Fiji and PNG businesses, as required to achieve 100% under the RE100/CDP Standard.
4 2021 baselines for scope 1, 2 and scope 3 upstream emissions targets adjusted for COVID-19 pandemic and other impacts. Refer to our 2023 Sustainability Index and Datasheet.
5 Refer to our 2023 Sustainability Index and Datasheet for details of included Scope 3 upstream emissions sources.
6 Certification is obtained for Westpac’s Australian and New Zealand operations (excludes financed emissions) under the Australian Government’s Climate Active Carbon Neutral Standard for Organisations and the New Zealand Toitū net carbonzero certification respectively. Further information can be found on the Sustainability Performance Reports page on our website.

Our operational targets

In FY23 we reduced our direct scope 1 and 2 and scope 3 upstream emissions by improving the efficiency of our operations, consolidating commercial offices, operationalising agreements to source electricity from renewables and more actively working with suppliers. Since 2021 we have achieved a 66% reduction in our scope 1 and 2 emissions, surpassing our 2025 target of a 64% reduction by two years. From April this year we achieved a significant milestone sourcing the equivalent of 100% of our Australian electricity demand from renewables. Our key operational targets can be found above - under ‘Our action areas’. In addition to those, our operational water consumption and waste diversion targets are as follows:
  • Reduce water consumption in Australian workplaces by 15% by 2025 relative to a 2020 baseline​ 
  • Divert 80% of waste from landfill at Australian commercial sites by 2025 and 85% by 2030 relative to a 2020 baseline​.


Refer to page 13 of our Action Plan (PDF 1MB) to learn more about key initiatives focussed on reducing our operational emissions.

Natural capital

Natural capital is the Earth’s stock of renewable and non-renewable natural resources – including soil, water, air, minerals, plants and living things – that combine to yield a flow of benefits to people. Assessment of natural capital is important to support decision making that aims to conserve nature and reduce nature loss.
As a major financial institution, Westpac Group can play a significant role in supporting our institutional and commercial customers through engagement and lending, to conserve nature and reduce natural capital loss in the way they manage their business.


Our Natural Capital Position Statement (PDF 2MB) defines our ambition to become a nature positive bank – that is, a bank that supports nature positive outcomes. As at November 2023, for us, becoming a nature positive bank means developing our understanding of nature-related risks and opportunities for our business and customers, and seeking to develop processes to have regard to nature positive outcomes through our business and to support customers. Currently, our ambition and this Position Statement apply to our direct operations and lending to institutional and commercial customers. We expect this definition to evolve as our understanding matures.
