Unilever's designated "sustainable living" brands delivered almost half of the consumer goods giant's growth in the last year, it revealed yesterday. Defined by the firm as brands which have "integrated sustainability into both their purpose and products" and including high profile names such as Knorr, Dove, Lipton, Hellman's and Dirt is Good, Unilever's "sustainable living" brands grew 30 percent faster than the rest of the business, the company said. The firm revealed the positive results in its fifth annual report on progress towards its 2010 Sustainable Living Plan, which aimed to show that sustainability is "no longer a niche issue" for consumers and that "putting sustainable living at the heart of our brands" is helping to increase sales. The report confirmed Unilever's "sustainable living" brands grew faster than last year and also included a new survey by the company, which found 54 percent of consumers "want to buy more sustainably."
