Unilever has been crowned the world’s most sustainable brand, according to GlobeScan’s 2015 Sustainability Leaders Report. The Dutch FMCG giant, which recently achieved its zero-waste-to-landfill target, stole a lead of 27 percentage points on its rivals, having dominated the thinktank’s corporate sustainability leadership ranking for the past five years.

According to the report, Unilever’s is the leader in most of the world, although its leadership margin is largest in Europe. The research consultancy questioned 816 sustainability experts drawn from corporate organizations, governments, NGOs and other organizations in 82 countries.

The report highlighted a growing divide among experts over the importance of a clear, well-defined statement of corporate values versus a business model that favors sustainability. Some 26 percent claimed that corporate values were a key driver for sustainability, down from 27 percent last year, while 22 percent believe integrating sustainability into the core business model is more important, up from 15 percent in 2014.

Unilever’s next mission is to help improve the health and wellbeing of over 1 billion people by 2020 through its Enhancing Livelihoods programs.
