Sustainable Investing Meets Blockchain: ESG Attitudes and Crypto Investment Decisions

Abstract

Objective:This study investigates whether individual preferences for Environmental, Social, and Governance (ESG) principles influence portfolio decisions related to crypto assets. While ESG-focused investing is widely observed in traditional finance, less is known about how these preferences affect exposure to controversial assets such as cryptocurrencies, particularly considering their environmental concerns (e.g., energy-intensive mining processes). Methodology:The analysis uses data from the 2023 Austrian Household Finance and Consumption Survey (HFCS), which includes responses from a nationally representative sample of 2,000 individuals. The study employs descriptive statistics to profile investors, Pearson correlation analysis to examine bivariate relationships, and Ordinary Least Squares (OLS) regression to assess the effect of ESG preferences on crypto-asset investment, controlling for age, risk tolerance, and financial literacy. Results:The findings reveal a statistically significant and positive relationship between ESG preferences and crypto-asset exposure. ESG-conscious individuals are more likely to invest in cryptocurrencies than in traditional asset classes such as bonds or equities. The OLS model indicates that a one-unit increase in ESG preference score is associated with an average increase of €302 in crypto holdings, holding other variables constant. Correlation analysis supports this, with a coefficient of r = 0.28 between ESG scores and crypto exposure. Conclusion:Despite concerns over the environmental impact of certain cryptocurrencies, ESG-minded investors show notable engagement with crypto-assets—likely driven by innovation, decentralization values, or interest in ESG-aligned blockchain projects. These findings suggest a shift in how sustainable investing is understood in the digital age and underscore the need for nuanced ESG frameworks in crypto markets. The study offers valuable insights for policymakers, asset managers, and sustainability advocates aiming to guide the future of responsible digital finance.
