National Geographic has just completed its second annual study on personal choices toward making the world more sustainable. Working with GlobeScan, an international polling company, the results are presented as their Consumer Greendex.
A total of 17,000 consumers in 17 countries answered questions on their energy use, conservation, transportation choices, food sources, use of green vs. traditional products, attitudes toward sustainability and the environment and knowledge of related issues. The study will continue annually to track the changes and progress.
You can test your personal Greendex, too. Click here to measure your own sustainable behavior.
