I think it is important to be part of organizations like the US Green Building Council. They are the guys behind LEED certification. All I had to do was pay $300….and anybody can become a member.
The money goes towards the good work they are doing. There are chapter organizations and other benefits which increases my exposure to other green minded businesses. I am happy I did it. It a little like getting a subscription to a magazin3e. It increases you activity in a certain area.
Some cynics point out that any crappy company can become a member to greenwash their image. True. But who cares. At least they paid money to the organization which helps in other ways.
