green suppliers?

I am into the phase of my business plan where I am seeking out reliable suppliers who are also committed to responsible business practices- both to the earth and to the people on it. I would love to use all small suppliers, closely connected to the materials they have created. Easier said then done. My question is how do you trust the name organic? Some products are certified, but many aren't. And the truth is, how many of us really research the products we buy to see if they are really what they claim to be? There are so many factors to consider: organic, sustainable, local, fair trade. And do we ever really trust that the government is closely watching and testing to see what goes into our food and products? Can we trust products coming in from other countries? It would be so easy to mislead. Some of these materials are coming from 1/2 way around the world. Passed through hundreds of hands. Can I trust what I am buying? Do you?
