The only app that pits volcanoes against spaceships. Learn how the carbon footprint of one thing stacks up against another. Simple, yes? Let’s CARBONIZE.

    A pear is worth 200 something in carbon emission, #CarbonizeFACT


    grams CO2e

      Now that’s a fact that needs sharing. And for every 100 shares, we’ll plant a tree with American Forests’ Global Re-leaf Campaign that will store 1 tonne of CO2. Neat.

      10,304 shares and counting. That’s 1,030 tonnes of CO2 dealt with.


      Where’s your data from?

      Data comes from Mike Berners-Lee’s authoritative book, How Bad Are Bananas? References are too extensive to list here, but include the Carbon Trust, Defra, BREEAM, WWF, the Stockholm Environmental Institute and The Guardian.
