David Jones, global CEO at Havas, is considered one of the world's most influential advertising figures, overseeing the movements of the global communications company across 75 countries.
David is an advocate for the role of business in creating sustainable change, believing that brands have an important part to play in encouraging consumers to make more sustainable choices. Aiding business in this journey is advertising, an industry in which David has had an impressive impact over the last decade.
The Havas chief has been arguing that social media plays a critical role in making leaders, corporations and governments more socially responsible and transparent.
"People have basically been empowered by digital and social media to hold businesses and leaders accountable and in the future in my view, the most successful businesses will be those that are the most socially responsible," he said in a recent interview.
Recognising an empowered younger generation, David believes that the digital revolution has put power into the hands of young people. In 2009 he co-founded One Young World, a non-profit organisation that provides talented young people with a global platform through which to effect positive change.
In an interview with Jo Confino in 2011, David said: "The young generation is unique: there has not been another time in history when the youngest people understood the most about what is going on in the world.
"It is also the most socially responsible generation we have ever seen. They are not the same as the rebellious teenagers of the past; they are not saying: 'Why does business have to make money and capitalism is evil?' They get the fact that business can make money but in the right way."
David was the driving force behind Kofi Annan's TckTckTck campaign, which Havas describes as "one of the most successful ever social media movements in history". The global petition saw 18 million people sign up and become "climate allies", calling for action on climate change.
