Australian Banks and their ESG Requirements for Business Loans

When a business seeks a loan from an Australian bank, it may be subject to implicit ESG assessments as part of the bank’s due diligence process.

Environmental, Social, and Governance (ESG) considerations are becoming increasingly important in the financial sector, particularly in the context of lending practices and business loans. In Australia, banks are integrating ESG factors into their lending decisions and into their risk assessment processes when providing traditional loans to businesses. This shift reflects a broader global trend towards sustainable finance, driven by a growing recognition of the financial risks associated with climate change and other sustainability issues.

This blog post will explore the specific ESG requirements and assessments a business may face when seeking a traditional loan from a bank in Australia. It synthesizes information from the practices of various Australian banks, reflecting some of the current trends and expectations. Note that while most banks have already in place a suite of sustainable finance solutions such as Green Bonds, Sustainability Linked Loans, Green Deposits, Social Impact Bonds and so on, these are not part of the scope of this analysis.

ESG Requirements for Traditional Loans

When a business seeks a loan from an Australian bank, it may be subject to implicit ESG assessments as part of the bank’s due diligence process. These assessments evaluate the potential environmental and social impacts of the business’s operations, as well as its governance practices. The goal is to identify any ESG-related risks that could affect the business’s financial performance or reputation.

Australian banks have developed various frameworks and criteria for ESG assessments. The practices regarding ESG assessments vary, but there are some common themes. Many banks have made public commitments to align their lending portfolios with net-zero emissions targets by 2050, in line with the Glasgow Financial Alliance for Net Zero, and the Equator Principles among others. This commitment influences their lending decisions, as they seek to support projects and businesses that contribute to a low-carbon economy.

Let’s take a closer look at these ESG related practices and requirements in place for several individual banks operating in Australia, for when a business approaches them requesting a traditional loan.

Commonwealth Bank of Australia (CBA)

CBA integrates ESG considerations into its lending practices, emphasizing responsible finance and positive impact. Its approach combines risk assessment, innovative financing, and a commitment to sustainability to support businesses seeking traditional loans. Here are some key aspects from CBA’s approach:

  • CBA is a signatory to the Equator Principles and introduced nine ESG Lending Commitments in 2014 which guide CBA’s approach to responsible lending across all business loans.
  • CBA has developed an ESG Risk Assessment Tool that plays an integral role in the lending decision process. This tool helps evaluate the ESG risks associated with any business seeking a loan.
  • CBA actively supports sustainability transitions for its customers by helping them reduce emissions, adapt to climate change, and drive positive social outcomes. Its strategy aims to address climate risks while harnessing opportunities.


Westpac aims to be a partner in sustainable action, helping businesses meet their ESG ambitions while ensuring sound financial practices. Some of the key points regarding Westpac’s approach are:

  • All transactions must pass Westpac’s usual credit risk assessment process to determine their viability.
  • Westpac embeds three lines of defense (3LOD) to consistently apply risk classifications across all lines of business. This ensures that ESG risk assessment aligns with the bank’s commitment to responsible banking.
  • Within its Sustainable Finance Framework, Westpac defined a Sustainable Finance Taxonomy that classifies loans and bonds based on their environmental, social, and sustainability impact.
  • Part of the Institutional Bank, Westpac’s sustainable finance team provides tailored solutions to transition businesses toward a low-carbon economy.

National Australia Bank (NAB)

The key aspects of how NAB assesses ESG risk are:

  • NAB has established ESG Risk Principles that provide a framework for responsible lending and help ensure that lending decisions align with sustainability goals.
  • NAB’s credit risk assessment and due diligence processes include: Origination and Internal Review (evaluating credit applications based on relevant sector, business activity, and geography), Evaluation (assessing ESG risk as part of the credit risk assessment), Approval (ensuring alignment with NAB’s risk appetite).
  • NAB maintains a list of High-Risk ESG Sectors and Sensitive Areas. This list assists in identifying sectors and activities with higher inherent exposure to ESG-related risks and outlines sectors where NAB has restricted or no risk appetite.
  • NAB considers three main areas of customer-related ESG risk: General ESG Risk (Includes climate risk, nature-related risk, human rights and animal welfare), Environmental Contamination Risk (if lending involves potential environmental contamination risks), Equator Principles (NAB is a signatory to the Equator Principles, which guide environmental and social risk management in project finance and corporate loans).

Bank of Queensland (BOQ)

BOQ integrates ESG considerations into its lending practices, ensuring responsible banking while managing risks. Here are the key aspects of how BOQ assesses ESG risk:

  • BOQ recognizes its corporate and social responsibility to maintain a lending portfolio comprised of sustainable businesses. The bank identifies industries that fall outside its risk appetite or require additional risk assessments.
  • All lending decisions undergo thorough evaluation by a credit decision team. Key considerations include: compliance with historical and ongoing legislation and regulation, potential future liability for environmental issues, sustainability of income sources and asset values used as security, independent third parties may also assess risks on the bank’s behalf.
  • BOQ’s process includes: understanding customer businesses, having a clearly expressed risk appetite, evaluating potential issues throughout the credit decision and management process, implementing credit policies to identify risks and issues.

Australia and New Zealand Banking Group (ANZ)

ANZ has established specific requirements and assessment processes for businesses seeking traditional loans:

  • ANZ has a Social and Environmental Risk Policy that outlines standards and due diligence processes applicable to business customers, ensuring that social and environmental impacts are considered during lending decisions.
  • The bank also adheres to accompanying “sensitive sector” requirements.
  • ANZ has implemented processes to assess customer vulnerability to climate risks, particularly for high-risk sectors.


ESG requirements and assessments are reshaping the lending landscape in Australia. Banks are adapting their practices to meet the demands of a changing world, where sustainability is not just a moral imperative but also a financial one. Businesses seeking loans from banks are likely to face ESG requirements and assessments. They must be prepared to demonstrate their commitment to ESG principles and show how they are mitigating related risks. These requirements are not only beneficial for the environment and society but also present opportunities for businesses to grow, stay competitive, and access affordable capital. The future of finance is green, and Australian banks are at the forefront of this transformation.
