My brother sent me an article from FT.com, website of London's Financial Times.

The article's about some companies in Britain that are going to start adding "grams of CO2" to food labels to indicate approximately how much carbon dioxide the production of the item generated.

Well, Cadbury is one of the companies mentioned in the article, and I just have to mention that Tom's favorite candy in the whole world is Cadbury's Dairy Milk chocolate bars!

Quoting from the article: "Many of these companies are working with the UK government-funded Carbon Trust, which has helped to develop certain methodologies for measuring the carbon that went into manufacture. The Carbon Trust says more than 150 companies have approached it about using the labels.

"Mr Murray says the process takes several months for the first product or service, but faster to roll out subsequently to other products. Companies have to scrutinise factors such as their electricity usage, their transport, heating, their use of materials, and any greenhouse gases produced by chemical processes in their manufacturing.

"The cost of the process varies widely from one company to another, from several thousand pounds to £10,000 or more. Undertaking such a review can be beneficial, Mr Murray reports: companies can find and solve inefficiencies in their supply chain, such as cutting their energy use. He estimates most companies could shave at least 20 per cent from their energy bills alone without major changes."

Imagine that, companies could actually cut their energy use just be going through the process of really understanding the energy consumed during the manufacturing process!

So far it is just starting in Britain, but with any luck, it will spread throughout the planet, and become ubiquitous, like the nutrition labels we see here.

I can see my thought process now: Hmm, should I get a Kit-Kat or a Snickers bar? Let me see, which has more calories? Now, which produced more CO2? Decisions, decisions!
