We're always interested in working out how to help people talk about products, services and ideas we care about. Carbon Brilliant (or maybe just Brilliant?) is a little idea we had. It's really just another carbon offsetting service. The major difference is that we invented this one (although it'll probably never actually see the light of day). It's a little bit viral too.
Here's how it works:
Someone pays Brilliant either £20, £30 or £40 (depending on the size of their car) and Brilliant offsets their emissions. In return, they get a sticker to put on their car windscreen that tells the world that they've offset their emissions for the whole year. (Based on the Road Tax Vignette principle).
The sticker scheme works because it's a mark of pride. It shows that the user cares, but it isn't just about bragging; it's a way to share the idea, spread the meme and support the cause. It's a social object that's inherently viral - you can see whole groups of friends picking the idea up and running with it.
Oh, and the message, call to action and pricing are all super-simple. That's important.
