Consumer goods maker Unilever (ULVR.L) says its brands that most fully embrace its CEO’s passion for sustainability perform the best, adding fuel to its oft-repeated argument that social responsibility is good for business. Of the more than 400 brands Unilever sells, those with the strongest sustainability credentials — such as Dove, Lifebuoy, Ben & Jerry’s and Comfort — have seen sales grow at a high single-digit or double-digit rate over the past three years, Unilever said on Tuesday.
