Concordia University study identifies drivers of bottled water consumption

A study published in the Journal of Cleaner Production reveals that awareness of plastic pollution and microplastics does not necessarily reduce the consumption of single-use bottled water. Researchers at Concordia University surveyed over 15,000 individuals across 81 countries to understand global drinking habits.

The findings indicate that convenience, advertising, and perceived safety are primary drivers for purchasing bottled water. Approximately 78% of respondents reported being in locations where safe drinking water was unavailable, making bottled water a practical necessity for many. Lead author Sarah Sajedi noted that awareness of health hazards does not always translate into behavioral changes.

Demographic trends showed that younger and more highly educated respondents were more likely to use single-use bottles, often citing convenience and germ protection, though they were also more likely to recycle them. In contrast, older respondents were more inclined to use refillable bottles. Additionally, increased exposure to bottled-water advertising was statistically linked to higher consumption rates.
