American retailer Whole Foods has teamed up with quirky chocolate manufacturer Bloomsberry & Co and TerraPass to introduce a new eco-friendly chocolate bar, in what has to be the best excuse yet to eat more chocolate.

Each ‘Climate Change Chocolate’ bar comes with a TerraPass offset of 133 pounds of carbon dioxide reductions, the average American’s daily carbon impact. The bar’s packaging includes helpful hints on ways to lighten your environmental impact, while its production and distribution are carbon neutral.

TerraPass itself was set up in 2004 as a for-profit social enterprise to allow individuals and businesses to take responsibility for their carbon emissions. As its core business, the company sells annual ‘passes’ calculated to offset emissions for companies, households and even student residences. Individuals can also buy carbon offsetting certificates as gifts, or purchase a TerraPass to offset the environmental impact of weddings and other events.

The collaboration between Whole Foods,  Bloomsberry and TerraPass is a great example of a clever and mutually beneficial brand partnership . Whole Foods gets to support its positioning as an environmental leader in retail, Bloomsberry gains a new distribution channel for its premium chocolate, and TerraPass has an opportunity to introduce carbon offsetting to new consumers, who will hopefully then upgrade to its annual products.

As a new product concept, it’s a lovely idea. It’s easy to imagine consumers choosing Climate Change Chocolate as a gift, and what chocolate lover could resist the idea of doing some good with their daily munch? There’s only one better product that I can imagine – a chocolate bar that gives you a way to offset the calories. Now that’s one I’ll be looking out for…
