World Resources Institute Offices
World Resources Institute was going green long before Al Gore ever told them to. Back in 1999, when the rest of the energy consuming world was in the dark ages, WRI was already using sustainable wood products, reclaimed wood, and consuming energy from renewable sources.
The institute itself is located in Washington D.C. near Union Station. Their work encompasses many fields such as the reversal of ecosystem degradation, information access for all, and climate protection. Suffice it to say, WRI is looking out for the future.
