Sustainability Signals

Twice a year, Deloitte surveys roughly 20,000 respondents in approximately 20 countries to explore how environmental awareness and related behaviors are evolving worldwide. The study—which is part of a broader survey on consumers’ intentions and behaviors—includes three focus areas: sustainability attitudes and beliefs, personal choices, and workplace engagement. The results can help leaders track how attitudes about the environment and sustainability are affecting daily lives, yielding important signals about how consumers, employees, and communities are changing over time.

Trade-offs for sustainable products

Globally, about half of consumers surveyed by Deloitte since 2021 purchase at least one sustainable product every month. However, sustainable products can come with trade-offs, including perceptions of higher costs, lower quality, or diminished performance. Even with the rise in global climate change awareness, for example, demand for sustainable products has not changed much, and has even slipped a bit over the past few years.

KEY TAKEAWAY

Insofar as price remains a challenge for people making sustainable product purchases, demand is likely to stall if consumers are forced to choose between what’s better for the planet and what’s better for their wallets. Companies that can offer competitive prices many find greater demand for their products than current sales seem to suggest.
