Do green contractors need a green certification?

Home Construction Pictures With so many contractors claiming to be green, it's a good idea to check for certifications. See more pictures of home construction.

Does a contractor need to be certified to offer green construction? The short answer is no. Any contractor may advertise green design and construction on a Web site, business card or other advertisement. A contractor offering green services without certification may be self-taught, learning green best practices from books or publications. Or a self-titled green contractor may not have been taught at all and may purely take advantage of the positive marketing gained by calling a company green.

To help homeowners distinguish among green contractors, a number of organizations now provide green certifications to different types of contractors to offer proof of their expertise. So why is certification so important when considering a green contractor?
