Responsible investors

As an investment manager with a long-term investment horizon, Maple-Brown Abbott believes that responsible investing enhances our investment decision-making and ultimately leads to superior long-term returns for our clients. 

We have a deeply integrated approach to environmental, social and governance (ESG) across each of our investment strategies. 

Our ESG framework spans four pillars of integration, stewardship, investment solutions, and governance and is underpinned by a suite of ESG policies.

ESG integration

Each investment team integrates ESG factors and risks, drawing on our strong in-house analyst capabilities to incorporate ESG considerations into each step of the investment decision-making process. 

We have developed proprietary frameworks to assess material ESG issues such as climate risk. These issues are then incorporated into factors such as company valuations, volatility scores, or strength of governance. This process helps inform our investment decision making and portfolio construction.


We hold ourselves to the same high governance standards we expect of the companies we invest in. Our approach to disciplined investment governance and ethical conduct is guided and supported by a suite of Board-approved ESG policies. 

Beyond our investment activity we maintain high internal standards across our own social and environmental performance, as well as governance standards. These include, for example, a code of ethics, human rights position statement, inclusion and diversity and whistleblowing policies. 

Our Climate Change Report, published in alignment with the recommendations of the Taskforce on Climate-related Financial Disclosures, provides more information on our governance, strategy, risk management and metrics in relation to climate change.


Buying shares in a company is just the beginning. A key component of our responsible investment framework is our comprehensive stewardship approach to company engagement and proxy voting. We actively engage with company boards and management to drive more sustainable long-term outcomes for investors and publish an annual report on our key themes and activity.


As active, long-term investors, we take our ownership responsibilities seriously and regularly meet with the companies we invest in. Engagement initiatives are the shared responsibility of portfolio managers and investment analysts, with insights incorporated into our investment research and portfolio decision-making. We may also hold ESG-specific engagement meetings with companies to undertake deep-dive research on certain topics.

Proxy voting

It is our policy to vote on all proxy resolutions at all investor meetings for investments that we directly hold on behalf of our clients unless, in exceptional circumstances, we believe it is in best interests of the client to abstain from voting. Our voting decisions are informed by a range of factors, with the key guiding principle being the best interests of our clients as investors.

Investment solutions

All Maple-Brown Abbott investment strategies integrate ESG into their investment process and our specialist capability allows us to work with clients to create bespoke solutions that meet their specific ESG needs.

Our Australian equities investment team offer the Maple-Brown Abbott Responsible Investment Fund, an actively managed Australian share fund that delivers responsible investment through the adoption of an integration, engagement and negative screening strategy.

We are regularly assessed by external frameworks on our ESG approach and performance and maintain leading ratings across all assessments.
