Tim Cook turned up in Manhattan today, to help kickoff the Climate Week NYC 2014 conference. The CEO was invited to speak as part of the 'enterprise-focused global solutions' portion of the event, and he participated in a short on-stage interview regarding Apple's carbon footprint.
More specifically, Cook talked about the various things Apple is doing to reduce its carbon footprint. Not only is it working to ensure that many of its facilities are run on renewable energy, but it's also working to make impactful changes through its supply chain and at the product level.
