Unsustainable Sustainability?
Is the sustainability movement becoming unsustainable? According to the Leonardo Academy, GreenBuild 2006 was responsible for the following emissions: 
- Carbon Dioxide = 13,269,500 lbs
- Sulfur Dioxide = 5,100 lbs
- Nitrogen Oxide = 17,900 lbs
- Particulates (PM10) = 2,800 lbs
- Mercury = 0.0389 lbs
While several companies (and individuals such as myself) donated/purchased emission reduction offsets through the Leanardo Academy's Cleaner and Greener Program, do those actions mitigate the full effects of 13,000 assembling in one location to talk about sustainability? Attendance for GreenBuild 2007 is expected to be more than 25,000! Do the benefits outweigh the environmental costs?
