On the home page drop-down menu there's a page About Pure Planet, which includes this statement:
"Pure Planet was founded by friends who wanted to offer green energy for less than brown, polluting power. We use smart technology and a shared community to make being sustainable the easy choice. If renewable is a sacrifice we'll all lose.
We're a private, independent company. BP holds a minority shareholding of just under 24%. As one of the largest energy brokers in the world, BP buys all the renewable electricity and carbon offset gas on behalf of our Members."
That's at least a start in answering your question?
