The company eFormic introduced , which consists of carbon-neutral labels that can be placed on a product and a Web site that lets consumers see how a product has been carbon-neutralized.

Every product you buy, whether it's the orange juice you drink at breakfast or the fuel you put into your Toyota Prius, results in the production of carbon dioxide that contributes to global warming, said Pieter van Midwoud, CEO and co-founder of eFormic.

To offset these emissions, many companies pour money into projects that replace nonrenewable energy with , or plant trees to absorb carbon dioxide. If such a company buys a CO2code, it can put a label on a product that certifies the project is carbon neutral and provides consumers with a code that can be entered into the CO2code Web site. Entering the code brings the consumer to a page showing the amount of emissions caused in the production of the specific product, and information on a climate project intended to balance those emissions, complete with a Google Maps image showing the location of the project.

Companies can give consumers a choice between multiple programs. For example, a person who buys orange juice can decide whether to balance the emissions by supporting a solar project in California or a overseas. If a project isn't chosen, the system automatically assigns one after a set period of time.
