Green infrastructure is becoming a prominently used term in planning, policies, and goals at all levels of government and throughout the country. But the term means different things to different people. In fact, there is enough variety in the green infrastructure concepts being bantered about that the definition of green infrastructure is a main tenant of one article (Allen 2012) in this special issue of Environmental Practice. The use of the term can indeed become very confusing among the uninitiated. Green washing is a term used to describe services or products that make an unsubstantiated claim of being green. Thus, it is important, as several of our authors note in this special issue, to be clear about what is meant by green infrastructure so as to not end up with it on the heap of green washing or discarded buzzwords.
