Opportunity Zones offer an attractive investment incentive for low-income communities, with the intent being that these investments will have a positive social impact. However, the law does not require a means of measuring the impact. To meet this need, the U.S. Impact Investing Alliance has developed a framework for ensuring positive results. "Opportunity Zones represent a once-in-a-generation opportunity to spur private investment into America's distressed communities," said Fran Seegull, executive director of the U.S. Impact Investing Alliance. "However...it is important that those entering this market remain committed to transparency and community engagement."
