Unilever’s threat to withdraw its advertising from online platforms such as Facebook and Google if they fail to eradicate content which “create division in society and promote anger and hate” is a powerful statement.

It reveals the keenness of the consumer giant, one of the world’s largest advertisers, to tackle a major challenge of modern society.

Under CEO Paul Polman, Unilever has sought to define how a large multinational can be a responsible corporate citizen – an approach many peers are starting to follow or at last observe carefully.

Many of these companies are aware that investors are increasingly in tune with calls to improve our planet and society, so are seeking to transform themselves.

It’s a powerful message that companies- with their global reach and dynamic leadership- can act in ways that governments and intergovernmental organisations often can’t. They can be a force for good, if the possess the right degree of will and commitment.
