From their site:
Everything we do has an impact.
When you buy a product, you’re buying more than just that product. You’re buying and supporting everything that’s gone into that product — the good and the bad.
With C-Minus™ we’re taking a big bite out of the bad.
Buying a Guyot Designs C-Minus™ product is a vote of support for corporate, environmental and personal responsibility.
Display yours with pride knowing that each of our C-Minus™ products comes bundled with more than enough green house gas offsets to, well, offset the negative impact of their manufacture.
Beyond Carbon Neutral
C-minus is a departure from the current trend toward “carbon neutral”. We are taking it a step further by making our products carbon negative and we are giving you, our customers, full visibility into the process.
Detailed Verification
When we make a product within our C-Minus™ program it receives a unique serial number. You can use the serial number on our web site to find the specific sales transaction that purchased and retired the offsets. Search for the serial number on our site and you’ll have access to the transaction records, detailed verification reports, and the scientific assumptions that went into the generation of the offset.
The C-minus™ program was designed in conjunction with the Environmental Resources Trust (www.ert.net) a Washington, D.C. based 501c3 non-profit that provides rigorous evaluations of offset projects. Guyot Designs has purchased and retired offsets through ERT’s greenhouse registry.
Effective Solutions
For current C-Minus™ products we’ve purchased offsets from Commonwealth Resource Management which captures methane from old landfills to generate electricity. To learn more, click here.
I have to tell you that I love, love, love their stainless steel bottles. They have a quart size. They have a wide mouth. The lids are tethered to the bottle. They are sturdy without weighing 2 pounds. The commuter fits into my stroller cup holders! They are just perfect in every way! I really tried to come up with something on the negative side to keep this a balanced review and I couldn’t. I have gotten a couple of strange looks from my friends and family when I start raving about this bottle. These bottles are perfect for anyone anywhere. The do offer a handle that attaches to it but were out when I got mine, so I haven’t had a chance to try it out yet.
The squishy bowls are loved by my little. He does everything from carry balls around in them, try to sit on them, to actually using them for eating.
The micro-bites carry a c-minus rating as well and are really good travel and camping utensils. My set are going to live in my glove compartment and have already come in handy a time or two.
Their products are ethically made in China. I haven’t been able to find a steel bottle that isn’t.
I wanna win!
