2020 Sustainability Report: Empire State Realty Trust

DATA-DRIVEN PERFORMANCE The foundation of our sustainability program is to measure, manage, and evaluate performance against our goals. We leverage data management platforms and cutting-edge technologies to provide advanced analytics and insights to inform and improve our performance. We partner with a leading energy analysis firm to review energy supply, demand, budgets and pricing to plan accordingly for energy supply and current and future renewable sources. Our data management platform provides advanced optimization, and real-time metering and monitoring. We leverage industry-recognized frameworks and standards including GRESB, SASB, TCFD, and GRI to inform our strategy and evaluate progress against our goals. Annually, we calculate greenhouse gas emissions in alignment with the Greenhouse Gas (GHG) Protocol. To ensure accuracy and transparency in reporting, third-party verification is performed in alignment with the ISO 14064-3 standard. ENERGY EFFICIENCY AND CARBON EMISSIONS To achieve our goals, we focus on ROI-driven energy efficiency strategies in leading technology and advanced analytics—supported by quantifiable performance improvements across the portfolio. We have developed a holistic energy efficiency approach with tactics to support our assets. To keep driving down our carbon emissions, we will continue to reduce our energy consumption, procure renewable energy credits to offset emissions from electricity consumption, evaluate opportunities for on-site or community-based renewable energy and storage where viable, and partner with policymakers to drive a renewable and resilient grid.
