The prospects for the first completely green Real Estate Investment Trust, or REIT, are closer to becoming reality. A well-known pioneer in the commercial real estate industry has registered an offering with the SEC for a REIT called Green Realty Trust, Inc. As reported first by CoStar Group, Rob Hannah, CEO and co-founder of TSG Real Estate, a Chicago firm, has made what appears to be the first foray into an all-green REIT. There are other REITs that have a significant number of green properties in their portfolio, such as Liberty Property Trust (NYSE:LRY), which has 21 green buildings in its portfolio of about 700 properties.
