Timberland is using outdoor imagery and humor to convey a message of environmental accountability in a new “Nature Needs Heros” ad campaign for print and television for its Earthkeepers footwear. Each pair is made with 1.5 plastic bottles. The spots are slated to appear in Europe, Asia and North American during live sports, prime time and late night programming. In a related matter, Timberland conducts its 13th annual “Serv-a-palooza” where more than 4,800 volunteers at 160 project sites generated 35,000 hours of service. Work included classroom renovations in Zhuhai, China, and restoration of a wildlife reserve in London.
