The Greendex uses a simple rollover map with different shades of green to clearly illustrate differences in consumer behavior. While the mouseover behavior can be a little tricky at times, the simplicity of the map format is ingenious.
No surprise, the US is at the bottom of the green scale, while Brazil and India are doing the best. The map points out that consumer-istic, wasteful behavior has got to go.
The really fun part of it is that you can take a quiz to see what your own “Greendex” is, so you can compare how well you stack up against the masses. They also have a guide on how to improve your Greendex. It’s a very well-done site.
Well done, National Geographic!
