LOW IMPACT DEVELOPMENT SITE DESIGN Case Study 2 – Green Washing “ The term is generally used when significantly more money or time has been spent advertising being green (that is, operating with consideration for the environment), rather than spending resources on environmentally sound practices.” -- Wikipedia.org Greenwashing is the unjustified appropriation of environmental virtue by a company, an industry, a government, a politician or even a non-government organization to create a pro-environmental image, sell a product or a policy, or to try and rehabilitate their standing with the public and decision makers after being embroiled in controversy. -- Sourcewatch.org PRESENTATION L62
