The green war? It has nothing to do with a central European political movement. Rather the conflict in question is about employee retention, overall well-being and leading by example. If one is in the business of auditing business, it should be a priority to have one's own affairs in tip-top shape.

The BBC shares with us that KPMG's and PricewaterhouseCoopers' newest architectural additions to the City of London have earned BREEAM ratings of "excellent" and "outstanding." Jon Barnes, manager of PricewaterhouseCoopers' properties, says that there were no excuses in installing the right equipment in a new building. PricewaterhouseCoopers' new headquarter cost ₤65,000,000 (~$107,000,000) to outfit with "outstanding"-rated infrastructure.

The PricewaterhouseCooper building will generate 25% of its own electricity through burning 45,000 liters of fry-oil bio-diesel a month saving the company about ₤1,000,000 annually. Perhaps the move will help to degrease London's fat-clogged sewers.

Mr. Buckingham, from architecture company BDP, has quite an interesting view on the subject; "... Regardless of the motivation, the environment is damaged less," he said to the BBC One World Service. The motivation, at PricewaterhouseCooper, is that the majority of their staff are described as being eco-conscious individuals under 35 and that they hope the new facilities will help with employee retention. 

About the buildings:

The 10-story, 60,884 square-meter PricewaterhouseCooper building was designed by Fosters + Partners and BDP will have room for 5500, four restaurants, 240 cycle spaces and a roof garden. It uses a cornucopia of technologies from solar water heating, on-site generation, solar shading and fully automated building management systems.

KPMG's new headquarters is a 15-story, 400,000 square-feet building housing 4,000 was designed by Kohn Pedersen Fox. The open-plan flexible space building was personally opened by the Queen herself and outfitted with greywater recycling, a grass roof, 200 cycle spaces and 20% of the building itself is recycled.
