Using "green" products is fashionable. In fact, it's hard to find a product that doesn't make some sort of "green" claim. It makes consumers feel like they have contributed to the "green" movement. Manufacturers and retailers enjoy recognition for doing something for the environment while enjoy increasing market share. While many products have contributed to the reduction of negative human health and environmental impacts, not all are as green as implied.
"Green" has become a politically correct buzz word without a meaningful definition. Its meaning to an individual is as different and unique as that person.
