Investing in green, social, and sustainability bonds: enablers of, barriers to, and challenges faced by Australian retail investment

The 2015 Paris Agreement reinvigorated global efforts to address the pressing challenges of climate change by calling for sustained reductions in carbon emissions and the transition toward a low-carbon economy. Achieving these objectives requires financing well beyond the scope of public resources, positioning capital markets as central to mobilizing private investment in environmental and social projects. Within this context, Green, Social, and Sustainability (GSS) bonds have emerged as a pivotal mechanism in debt capital markets, facilitating the flow of funds toward sustainable outcomes while meeting growing investor demand for responsible investment opportunities. Despite strong global momentum, the Australian GSS bond market remains comparatively nascent. Although retail investor appetite has been consistently strong, the scale of domestic issuance has yet to align with this demand. This chapter examines the drivers, barriers, and challenges influencing retail investor participation in Australia’s GSS bond market, situated within a broader context of economic dependence on fossil fuels and resource-intensive industries, alongside heightened vulnerability to the impacts of climate change. Employing an exploratory survey-based approach, the study generates a novel dataset capturing the lived experiences, motivations, and awareness of retail investors. It further explores perceptions of external review mechanisms designed to enhance the credibility of labeled bonds. The findings offer valuable insights for policymakers, regulators, and market participants seeking to deepen market participation and functionality. Ultimately, the chapter underscores the critical role of retail investors in advancing Australia’s sustainable finance agenda and supporting the nation’s transition to a low-carbon economy.
