Earth Aid- what's your experience?

I recently heard about a program called Earth Aid where you sign up and track your utility bills, then get credits for reducing your energy use based on the previous year's use. The way they do this is by bundling and selling your reduction in emissions (based on your energy savings). This sounds like a fantastic idea and a great way to incentivize energy savings.

But... I'm a bit wary of signing up because I can't find any reviews yet of actual users. I read the fine print ("individual member agreement"). The individual member agreement states that it lasts three years and then automatically renews (unless you request otherwise).

This is the part that I'm especially wary of (emphasis mine):

"I understand that the Program is supported in part by advertising revenue and that
Earth Aid may use my Member Information to (a) improve the Earth Aid Program; (b) deliver targeted banner or other advertisements on the Earth Aid website; and (c)
send me advertisements for third-party products via email or other mechanisms."

I really, really do not want to sign up for this if I don't have a way to opt-out of unwanted emails or "other mechanisms" (which sounds to me like it could be snail mail)... for 3 years.

Also, I rent my apartment and my landlord pays the water bill. I never even see it. I'm not sure if people who don't have all three utilities (electric, gas, and water) in their name are eligible.

Lastly, can I even participate in Chicago yet? Earth Aid Enterprises is based in DC and it's the only city mentioned so far. I didn't actually try to sign up yet (because of my concern stated above) so I'm not sure if it would let me.

So, I'm eager to hear from you if you are a member of Earth Aid.
