The Impact of Sustainability Practices on Financial Performance: Empirical Evidence from Australian Energy Companies

The thesis examines whether sustainability practices are related to the financial performance of Australian listed energy companies. The study analyses forty-three companies listed in the Australian Securities Exchange (ASX), publicly available secondary data sourced from the annual reports and sustainability disclosures covering the period from 2020 to 2024. The three most recognized financial performance indicators include the return on assets, return on equity and return on capital employed. They are measured on six indicators membership in the Dow Jones Sustainability Index, membership in the United Nations Global Compact, adherence to Global Reporting Initiative, corporate social responsibility disclosures, corporate sustainability rankings, and sustainable growth rate of companies. The study employs quantitative statistical techniques such as panel regression models and a vector analysis of autoregression in the analysis of both short and long-term links between sustainability practices and financial performance. The findings indicate the sustainable growth rate as the most predictable and predictable indicator of financial performance. Companies that have better internally funded growth potential are found to be more efficient in assets, have better shareholder payoff, and capital productiveness. Conversely, the involvement of global sustainability initiatives and the application of reporting systems, including the Dow Jones Sustainability Index, Global Compact and Global Reporting Initiative do not demonstrate the high immediate impact on profitability when considering the firm characteristics. Overall, the research results indicate that sustainability can enhance the financial performance when incorporated into the core business strategy and growth discipline but not as a symbolic or compliance-based process. Using the thesis, managers, investors and policy makers can find practical guidance to the sector since it has shown that, the creation of long-term value in the Australian energy sector requires the integration of sustainability into the finance and operations-based decision-making process.
