I got this via FCRN:
"Sustainability brand consultants Change have published a study in partnership with the organisations Climate Counts and Angus Reid Public Opinion. The study incorporates both actual measurements on climate change action being undertaken by over 90 companies across North America, and perception measurements of these companies’ actions by consumers. Companies include Coca-Cola, Groupe Danone, Nike, Gap, P&G, L’Oreal, Microsoft and Amazon.com.
The companies were grouped by sector (food/beverage shown), and the results illustrated in ‘perception / reality’ maps. In total, 10 sectors were mapped. Across every sector, MapChange showed a disparity between actual sustainability activity of brands, and consumer perception of sustainable activity of those brands – some were perceived as being greener than they actually are, while for others the opposite is true."
Here's the full report.
