Index Methodology

Q: What knowledge gap does the Index fill?

A: Other indices capture brands’ environmental efforts, their disclosure of environmental information or their corporate policies and actions. Until now, the public perception of brands’ sustainability efforts was largely unknown.

Q: Which brands are included in the Index?

A: To capture the image of the top global brands, Dalia picked the Interbrand100 list. The list provided globally recognisable logos, which could easily be assessed by respondents. This provided a benchmark to evaluate brands across 12 industries against each other. In the future, more industry-specific rankings will follow.

Q: Who rates the brands?

A: Each country has national census representative results with n = 1.000 respondents per country in the United States, United Kingdom, Australia, Canada, Germany, France, Spain, Italy, Sweden, Poland, Netherlands, Turkey, China, Russia, Brazil, India, Indonesia, the Philippines, Mexico, and South Africa. The total number of respondents surveyed is 20,000+.

Surveys have been adjusted for legal drinking age in the United States, Canada, Sweden, India, Indonesia, and Italy.

Q: How was the question asked?

A: In order to assess consumer perception, the SPI uses the following question:

How environmentally sustainable do you think the following brand is?

The term ‘sustainability’ was intentionally open to respondent interpretation in order to capture spontaneous reactions or associations to a brand.

Q: How is the score calculated?

A: A minimum of n = 500 people rated one brand. Only people who knew the brand were included in the calculations of the score.

To get the most information out of people’s answers, the Index looks at both the positive and negative associations of the brands people rate by creating a ratio of positive to negative scores.
