This post from Alternet says we should admire the following 12 countries for their sustainable policies:

1. Iceland
2. Switzerland
3. Costa Rica
4. Sweden
5. Luxembourg
6. Germany
7. Cuba
8. Colombia
9. Singapore
10. France
11. Norway
12. Finland

Now all these countries definitely have progressive policies that other countries can learn from. But with the possible exceptions of Costa Rica, Cuba, and Colombia, all these countries have a lot of heavy industry and finance. They have large carbon emissions. They have replaced a lot of their original natural habitat with ecologically sterile urban development and factory farming. They house corporate headquarters and investors that exploit natural resources and export urbanization and heavy industry abroad. It simply won’t work to take these best-of-business-as-usual, relatively-low-footprint models and copy them in developing countries on a much larger scale. The resulting footprint will still be much too large, and lead to collapse. So what we need to do is take bits and pieces of what they do well, but come up with a completely new, truly sustainable model.
