The data in this interactivity comes from the book How Bad Are Bananas? by Mike Berners-Lee.
Here is a chance to gain a better understanding of how our lifestyle choices affect our carbon footprint.
In this interactivity you will be asked to pair up items or activities with the amount of carbon used when producing or engaging in them. When you have matched a pair correctly you will be able to read some more information about that item/activity.
There are many more cards than appear in a single game, so you may like to play several times so that you have a chance to see all of the cards.
To find out more about carbon footprints you might like to watch Mike Berners-Lee Ted talk "The Carbon Footprint of Everything".
