"The motivation doesn't matter, the action matters," said Davies. "Motivation is irrelevant. The thing that matters is moving forward and reducing carbon dioxide – that's what matters to the polar bears."
"If the governments of the world aren't going to act then great, if it's the self-interest and profitability that's going to motivate companies to move then it's great and I'm going to applaud it," Davies added.
Environmentalists are optimistic that as more and more companies catch on to the greener lifestyle, more viewers, consumers and citizens in general will also start caring about the environment.
The leadership these companies demonstrate, they say, will make plenty of progress.
"News Corp. isn't alone going to save the polar bears," said Peyton Fleming, communications director for Ceres, an organization that works to promote global climate change. "But the pressure they exert on even the news media or the sector they are in or more broadly as a political and corporate voice is important."
