The World Wildlife Fund's

If you are thinking how to green your business a first step would be to join the World Wildlife Fund's Green Initiative Game Changer, a so-called "crowd-sourcing exercise", where companies are examples of green policies, products and business models that cut down the environmental impact and loss of biodiversity.

The initiative is based in the United Kingdom has not yet had the official route, what will happen next week, but the WWF has about 20 studies on its website. Some of them are well known - Better Place, an innovator in the transport sector - and others like Magenn Power, are still under the radar.

Anyone can submit case studies for the site, but WWF will monitor to ensure that only listed companies are credible. If the site goes forward, could be valuable for companies seeking a sustainability point of departure. If you want to increase the efficiency of water, for example, just check these case studies of smart buildings, low-water washing, and recycling water.
