Investors are more likely to opt for ‘green bonds‘, even when the actual environmental impact of said bonds is negligible, a new study by researchers at the University of Waterloo has found.
The study, which surveyed more than 1,100 participants, presented each with three different investment scenarios, and asked them to choose between bonds that varied in labelling, environmental benefits and financial returns.
It found that investors were more likely to invest in bonds labelled as green, even in a situation where non-green bonds offered higher financial returns.
‘Green’ labels
“Green labels on bonds and other investments indicate that the funds are allocated to environmentally sustainable projects, such as renewable energy, clean transportation, or climate adaptation,” commented Dr. Adam Vitalis from the School of Accounting and Finance. “The purpose of green labels is to promote sustainability.”
However, the study also noted that since investors rely on labels rather than conduct due diligence, there is an increased risk that they will sink capital into financial products marketed as ‘green’ that do not deliver real sustainability benefits.
“Greenwashing undermines investor confidence and risks diverting capital away from genuinely sustainable projects, slowing progress toward real climate solutions,” Vitalis, who conducted the study alongside Dr. Olaf Weber and Dr. Vasundhara Saravade from the Faculty of Environment, added.
Regulatory safeguards
The researchers call for stronger regulatory frameworks to standardise green bond labelling, more transparency and accountability in sustainability reporting, and better education for investors to assess the real environmental impact of their investments.
“Regulatory safeguards play a crucial role in addressing this by ensuring transparency, accountability and clear sustainability criteria in financial markets,” Vitalis added. “Emerging disclosure standards require firms to provide accurate, comparable sustainability information, which helps protect investors from misleading claims and ensure that financial capital flows to support meaningful environmental commitments and long-term sustainability goals.”
