 Sir Mike Rake, Chairman of BT Group. What are the key challenges facing the telecommunications sector? Well, I think the real challenge is the importance of ICT and telecommunications to society as a whole, to the global economy, to competitiveness, to education, to lifting people out of poverty, to e-government. It's become absolutely critical. It's become more a utility than a luxury. And that's what we have to understand. And that in itself creates challenges. How is BT addressing some of those challenges? Well, I think the challenge, the essential challenges, can we get fast enough that, you know, the demand for super passport ban globally is exponential, wherever you are in the world. That's what people need and insist upon. So the challenge is to make those investments, get a reasonable return, a fair return over a period of time, and to negotiate very complex and different regulatory environments right the way around the world, which has to be done. You know, the question, therefore, is having really good systems of interoperability and telecommunications, having as much as you can a level playing field for operating across the world, and for ensuring that across the world that ICT, the telecommunications providers, are providing what society really needs. What are the key roles for ICTs in achieving some of the sustainable development goals? Well, again, I think if we look at the challenge of the environment, they're enormous. And I think, you know, after a period when perhaps we weren't paying enough attention to the environment, politically, it's come right back on track, which is important. And I think these are very complex dynamics. And what's really clear is that ICT has a key role in dealing with this, whether it's smart metering, whether it's sufficient use of energy, whether it's recycling, everything comes down to the use of ICT to do this. It also comes down to telecoms companies. BT, for example, you wouldn't necessarily see that, consumes 0.7% of the national grid in the United Kingdom. So telecom operators themselves have a lot to do in dealing with their machinery, their equipment, their powered units. We all want superfast broadband and fiber. That requires power in a way that copper doesn't. So again, managing those dynamics when you're giving society what it needs and wants, and doing that in an efficient way, an environmentally friendly way, and it's in its absolute decor of what BT's trying to do. Develop home arms and machines that switch off when they're not being used, not on standby, makes a huge difference. All of those issues leading by example, as well as providing a means for others to improve their environmental levels of efficiency and responsibility are really critical.
