Executive Summary
Green leases have moved from a niche sustainability instrument to a key feature of commercial real estate. However, the machinery needed to make these leases work remains poorly developed by most organizations. This report draws on interviews and Verdantix survey data to provide practical guidance on how sustainability data should be structured, governed and validated under green leases. The central finding is that green lease data failure is rarely a technical problem, but rather a governance problem. Landlords, occupiers and investors should use the insights in this report to establish measurable and achievable green lease data frameworks.Summary for decision-makers
