Green technology is being embraced more and more within the tech industry.
Big players such as Dell, HP and Intel are all citing it as a driver for their new products, be it lower power consumption on a server or the materials that build it.
Businesses buying the hardware are also taking up the green gauntlet, seeing it as a badge of honour to draw an environmentally-conscious customer base, as well as a way to help cut costs.
Greening the mobile world
But what of the mobile phone industry? The handset is a piece of hardware we all use on a daily - or more likely, hourly - basis, but how green is this industry and what does it need to fix to become so?
Some steps have been taken. Manufacturers are starting to market phones as eco-friendly, suggesting there's a place on the shelves and consumer pockets for such devices.
As more and more old handsets pile up in our homes, services are popping up to recycle them. Some manufacturers are looking at ways to cut down on packaging, and shipping manuals built into the phones to save paper, while others are looking at green power for base stations.
One major move the industry has taken recently is to agree on a universal charger. Across Europe over the next year, major phone makers including Nokia will start producing their phones to work with a mini-USB charger, meaning we won't need a new power connector every time we pick up a new handset.
But are such steps enough, or are they merely the beginning of the transition to a green mobile industry?
Sony Ericsson's first steps
Sony Ericsson recently launched its attempt at green handsets.
Its global marketing director said at the time: "It's not about making normal phones green, it's about making green phones normal."
However, journalists quickly turned the meeting aimed to promote Sony Ericsson's green credentials into an interrogation about why the firm had only just made the moves - and what more they could do.
David Aeron-Thomas from Forum for The Future was in attendance. While he clearly approved of the new green handsets, even he openly condemned the company for not doing enough.
He said: "Sony Ericsson hasn't gone far enough yet, but they are doing great things towards this. The thing is you need to take customers and suppliers with you in long term partnerships."
At Forum for the Future, Aeron-Thomas works with many companies such as BT and Vodafone on green initiatives but to get on board they need to fit in with strict guidelines.
