Reader’s Digest has a new study that ranks countries and major cities.

On the cities front:

Using different data, we analyzed 72 major international cities and ranked them in terms of being green and livable. The sources included The Millennium Cities Database for Sustainable Transport (2001) by Jeff Kenworthy and Felix Laube of Australia’s Murdoch University, the World Bank’s Development Economic Research Group Estimates, and our own reporting on local environmental laws, energy prices, garbage production and disposal, and parkland.

And D.C., it turns out, scores pretty well, finishing in the top 25. And it’s the second best in the United States—-behind New York but ahead of Denver, Houston, Los Angeles, San Diego, and others.
