What is the sustainability premium ? Research shows that even in an era of scepticism, there is a strong consumer interest in sustainability. A PwC survey found that around 80% of consumers are willing to pay more for sustainably produced goods . This is supported by our 2025 UK consumer study, conducted in collaboration with the University of Exeter, which found 83% of respondents agreed.
But How Much more?
Read more about the sustainability premiumThe sustainability premium reflects how sustainabilty perceptions drive brand consideration and value. When real effort is not clearly shared, brands may miss opportunities (sometimes by up to 20%, depending on the products and how the information is presented). The qZERO score was created to address this problem.
