It's hard to say that one product is green and another is not. There are so many different factors that can make or break the "green flooring" status. If you don't pay close attention, you can end up buying cleaners or flooring materials that are advertised as "green," but are not actually good for the environment at all.
Let's look at bamboo as an example. Bamboo is known as green flooring as it's harvested from renewable resources. However, there are many "green status breakers" to look out for. Some manufacturers are using formaldehyde in the glue that binds bamboo flooring together. Others are actually clearing healthy forests to make way for monocultures of bamboo (an area where nothing but bamboo grows). In addition, some manufacturers are using chemical pesticides and/or fertilizers which can seep into drinking supplies and food crops. Clearly, these are not eco-friendly choices.
The lesson here is to be careful and don't be afraid to ask questions before making your decision. Find out about the products and methods employed in the making of the flooring before believing that it is truly green. Finally, don't be swayed into buying a so-called "green" product that defeats the purpose.
