With a growing number of CEOs publicly committing their companies to taking action on climate change, what difference can their pronouncements make? Can they persuade others to follow suit, or encourage governments to legislate?
Or is there still too much scepticism about the honesty of business? As Richard Branson has discovered, speaking out but not following through on commitments can bring its own reputational risk. He has been criticised for failing to deliver on a $3bn climate pledge made back in 2006.
There may also be justifiable doubts about whether one leader or CEO on his own can change the long-term course of his or her company. A speech, press release or strategy document does not necessarily translate into business behaviour five, ten or twenty years down the line.
