You have to keep in mind that Texans think they are in a different country. So they have a foreign policy all their own, involving selling oil to the dumb residents of other states while they build up their own sustainable infrastructure...

Dallas has company in its pursuit of long-term savings with the green approach to municipal projects. City councils in Austin, Houston, San Antonio, and Frisco have also passed resolutions or ordinances calling for future city projects to follow green guidelines for sustainability.

A number of large corporations have now embraced the "healthy workplace" standard at the urging of employees, says Houston architect Tim Murray.

College graduates who have been raised on the 'reuse and reclaim' mantra are actually asking recruiters where they will be working and in what sort of building."
