Investors with an interest in ESG and sustainability have a new tool, the FTSE EPRA Nareit Green Real Estate Index Series that allows investors to integrate ESG considerations in their portfolios of listed real estate. These new investment benchmarks “tilt” portfolio weights up or down according to the portion of the company’s net leasable area that has an eligible green building certification, and according to estimated energy efficiency, resulting in a portfolio with significantly higher energy efficiency and lower carbon emissions.
