Greenwashing, the practice of overstating the environmental benefits of products or practices, poses a significant challenge to achieving genuine sustainability.  
Alarmingly prevalent, a recent Which? study revealed that 84% of 1,000 products with green claims in the UK failed to meet at least one principle of the UK Green Claims Code. Whether intentional or accidental, the repercussions of greenwashing are severe: reputational damage, hindered progress towards sustainability, and potential legal liabilities.
