It is a pleasure and a privilege for us to share our 2021 Sustainability Report and present a year of continued achievement and commitment to our shareholders, tenants, team, and community. We have continued and expanded upon our industry leadership in sustainability, Indoor Environmental Quality (IEQ), and healthy buildings and moved strongly forward with actions to support our team and our community. We have a comprehensive techno-economic program, aligned with the Science-Based Targets Initiative (SBTi) 1.5 °C pathway and we have developed customized plans to address each goal with targeted ROI- based initiatives. We have stated our commitment to a 2030 carbon neutrality target for the Empire State Building and a 2035 carbon neutrality target for the balance of our office portfolio. In partnership with the New York State Energy Research and Development Authority (NYSERDA), we launched Version 2.0 of our groundbreaking energy efficiency retrofit program for the existing built environment. These case studies show a pathway and the economic case to achieve, in coordination with New York State’s Climate Leadership and Community Protection Act (CLCPA), our goal of 80% operational emissions reduction by 2030. Visit this free guide for office landlords to develop their roadmap toward carbon neutrality HERE. We led the industry as the first North American commercial portfolio to receive the WELL Health‑Safety rating, and we were one of the first to have our rating renewed. We piloted new IEQ technologies to position our assets to exceed leading IEQ health and wellness standards. We have made all these benefits accessible to all tenants, not just large tenants, through our IEQ Pre-Built Suites with energy efficiency at an accessible price point. Energy efficiency and health and wellness are available to all types of tenants at ESRT properties. We have committed to diversity, equity, and inclusion within our company and supply chain through training, mobilization, and engagement. In 2022 we were included in the Bloomberg Gender Equality Index. Per the policy we implemented in 2021, every bid should include at least one bidder from an underrepresented group and every vendor must agree to ESRT’s Vendor Code of Conduct. We have also invested to create better opportunities and inclusivity for diverse vendors. ESRT has also added to the quality of our community with enhanced engagement activities at the workplace and in our volunteer work. We have served our community through park clean-ups, oyster seeding, work in soup kitchens, and more. We sponsor company-wide volunteer events throughout the year and also provide volunteer time off to encourage our people to make a difference outside of the workplace at organizations of their choosing. In 2021 ESRT demonstrated continued leadership in a challenging time. We pushed forward on all fronts to continue to deliver value to our stakeholders and achieve our sustainability goals. There is more work to do, and we are committed to achieve.

ESRT OVERVIEW

We advance Environmental, Social, and Governance (ESG) principles through our industry leadership, expertise, and commitment to community. We establish and execute our sustainability framework to reduce our buildings’ impacts and foster health and resiliency. We do this with a focus on accountability and financial performance and care for the well-being of ESRT’s people and the communities where we work and live. Daily, we take steps to reduce the environmental impact of our portfolio, more than 10 million rentable square feet of commercial and retail space in the Greater New York metropolitan area, and have made plans for 2022 for the 625 high-rise Manhattan apartments we added to our portfolio in December 2021. We make investments and adjust our practices to achieve quantifiable improvement in energy efficiency, carbon emissions reduction, water efficiency, waste diversion, healthy buildings, and the wellness of our tenants and employees. ESRT’s leadership in energy efficiency and emissions reduction is locally, nationally, and globally recognized. We innovate, model, and implement steps to address climate change, and through our work deliver returns for, and protect, our stakeholders. This is the work on which we have based our goal to achieve carbon neutrality by 2030 at the Empire State Building and by 2035 throughout our entire portfolio. We are a 2021 ENERGY STAR Partner of the Year, and 76% of our office and retail portfolio is certified by ENERGY STAR, the national industry standard for energy efficiency. We earned a Five Star Rating from the Global Real Estate Sustainability Benchmark (GRESB) along with the highest possible score of an A for ESG disclosure and reporting. ESRT’s commitment to disclose and report progress against goals and initiatives transparently is in alignment with leading governance frameworks including GRI, SASB, and TCFD. ESRT’s emissions reduction targets have been approved by SBTi as consistent with a 1.5 °C climate scenario, the most ambitious goal of the Paris Agreement. Our commitment to the advancement of verified scientific approaches to healthy buildings and IEQ, which supports tenant well-being, has earned us the distinction of Fitwel Champion. ESRT partnered with the International WELL Building Institute and the Mayo Clinic to achieve the WELL Health-Safety Rating across 100% of our portfolio and was one of the first commercial portfolios in the Americas to achieve and be recertified for this rating. Our processes and policies support the effective implementation of these standards to ensure accountability and efficiency across our organization and ESG objectives. We are an example of successful implementation of comprehensive, innovative, and impactful ESG policies, stakeholder engagement, and clear and actionable corporate governance. Our expertise and dedication in these areas position us to facilitate sustainable and healthy buildings within our portfolio and share best practices with our peers.

INTRODUCTION

Materiality and Stakeholder Engagement

In 2021 we conducted a Materiality Assessment in alignment with TCFD and SASB standards to highlight the ESG issues most impactful to our business and stakeholders, based on their responses. The Materiality Assessment measured ESG topics based on each stakeholder’s impression of the topic’s impact and importance on the organization. Stakeholders included employees, peers, investors, service providers, government and community members. Impact refers to the effect an organization has on the economy, the environment and/or society, which can indicate its contribution (positive or negative) to sustainable development. Sustainable development meets the needs in the present without compromising the ability of future generations to meet their needs. A high impact implies that an organization’s contribution (positive or negative) could or will be large. Importance refers to the degree to which a specific metric/issue is aligned with the organization’s vision and purpose, and/or the extent to which stakeholders express concern for this metric/issue. A high importance implies that a topic is integral to the organization’s overall mission and operations.

SASB Standards focus on ESG issues expected to have a financially material impact on the company, aimed at serving the needs of most investors. TCFD provides a framework for climate- related disclosures to enable stakeholders to understand better the concentrations of carbon- related assets. ESRT aligned its materiality assessment with TCFD and SASB disclosure topics to ensure stakeholder expectations are addressed.

EMPIRE STATE REALTY TRUST: 2021 SUSTAINABILITY REPORT

Buildings presently consume 70% of electricity in the United States and account for almost 40% of Greenhouse Gas (GHG) emissions. In major cities like New York City, the built environment accounts for over 70% of GHG emissions. 1 At ESRT, we believe in the power of building performance to drive global and local emissions reductions, improve employee productivity, enhance our competitive position, mitigate our stakeholders’ exposure to future costs and degradation of value, and lead in environmental stewardship. We evaluate new and emerging technologies to optimize performance across our key priority areas, and advance our efforts towards the reduction of energy, GHG emissions, water, and waste and the enhancement of IEQ. Our decarbonization and sustainability programs include consideration of embodied carbon so that we balance optimization with reuse and lifecycle assessments. Our strategy and implementation of best practices, state-of-the- art technologies, and results-driven initiatives position us to set the standard for the built environment.

INTRODUCTION

Carbon Neutrality The Empire State Building (ESB) targets carbon neutrality by 2030 with an 80% operational carbon reduction, achieved through the implementation of energy efficiency and emissions reduction measures, an increasingly renewables-sourced grid in compliance with New York State’s CLCPA, and up to 20% offsets with off-site additive clean energy generation, Renewable Energy Credits (RECs), or other verifiable strategies. Owners, operators, and tenants of commercial properties must work together to meet carbon reduction targets as set forth in New York City’s Local Law 97 (LL97). Our work has proven that building interventions are required, along with planned major changes in power supply to the grid, to achieve NYC’s and international long-term targets of 80% reduction of GHG by 2050. The most impactful reduction by buildings is achieved through implementation of energy and emissions reduction measures at the asset level. Our groundbreaking deep energy retrofit at the Empire State Building, which began in 2010 has reduced GHG emissions by 54% from our 2009 benchmark. This version 1.0 work provided the real estate industry with a blueprint of what was then technically and economically possible in the built environment and was integrated into our entire portfolio. ESRT has just completed and announced in April 2022 an update of its 2009 roll-out that outlines further steps on our decarbonization roadmap, referred to as ‘ESRT 2.0’.

GOAL ESRT Carbon Neutral by 2035

ESRT’S DEFINITION OF CARBON NEUTRALITY

Reduce building operational emissions with a renewably sourced grid aligned with New York State’s CLCPA, offset residual emissions through clean energy generation and/or RECs, and report transparently, until net annual building operational carbon emissions are equal to zero.

Goals and Targets

In 2021 ESRT conducted an in-depth goals and targets exercise to ensure our goals are ambitious and supported by independently verified data. We focused on six categories for our portfolio: GHG emissions, energy, water, waste, and ENERGY STAR and green building certifications. To develop and establish these goals, we used 2018 as a baseline year to ensure goals met or exceeded our existing commitments such as NYC Carbon Challenge, US Department of Energy’s Better Climate Challenge and Empire Building Challenge. We also aligned our targets with industry standards and frameworks where possible, including the United Nations Sustainable Development Goals (UN SDGs).

EMPIRE STATE REALTY TRUST: 2021 SUSTAINABILITY REPORT

We perform energy audits on a regular basis (at a minimum every 3 years), procure RECs to offset emissions from electricity consumption, and partner with policymakers to drive a renewable and resilient grid. Our plan to accomplish our 2035 carbon neutrality target is to continue to implement these measures, perform evaluations of emerging technologies, and scope opportunities for on-site or community-based renewable energy and storage where viable. Our Chairman, President and CEO is the Chair of the Real Estate Roundtable’s Sustainability Policy Advisory Committee that focuses on federal legislation and engagement with commissions, departments, and agencies on the federal level. We have promoted energy efficiency throughout our portfolio since 2007 when New York City began its climate leadership under Mayor Bloomberg. ESRT’s participation included work on programs such as:

We implement Real-Time Energy Monitoring, conduct Measurement and Verification (M&V) audits and Tenant Engagement Management analytics, and perform quarterly M&V on energy projects. We partner with ConEdison and New York Independent System Operator (NYISO) on over 8 million square feet of our portfolio in their Demand Response (DR). With DR, we reduce our assets’ electricity usage through peak periods, reduce stress on the grid, and help prevent disruptions to service such as, brown outs and blackouts. All assets have access to a Real-Time meter data (RTM) tool designed for proactive demand management during demand response events.

INTRODUCTION

We implement water efficiency strategies to support our water reduction goals and minimize our impact on the environment. Our water efficiency initiatives include a combination of retrofits, submeters, and pilot technology.

Low-flow retrofits/upgrades As part of our standards, we continue to implement ultra-low- flow fixtures that we estimate to be 40–50% better than Code and are EPA WaterSense labeled.

Water submeters To monitor and measure water consumption by end use and identify areas for targeted reduction, we install water submeters for key water-using systems. We track progress from water efficiency upgrades, identify leaks from specific systems, and readily identify opportunities to increase water efficiency. Advanced software-based water use monitoring We have implemented an artificial intelligence software to detect and stop water leaks in select spaces, monitor water use, and analyze water use trends. This technology enables our property managers and engineers to expertly manage water consumption and make informed operational decisions in real time. As of December 31, 2021, 30% of our portfolio has implemented this smart technology. We plan to extend implementation of this technology across our entire portfolio to further reduce process water usage over the next year.

WATER The reduction of water consumption in buildings reduces overall environmental impact, drives operational cost savings, and contributes to the reduction of risk from fluctuations in water supply. Water usage reduction and water runoff quality and quantity management are critical issues. We address each of these through water processing, water fixtures, green roofs, and native xeriscape planting (where applicable). To implement our water policy and implement conservation initiatives we partner with our property managers and building engineers to understand the factors that influence asset water usage through collection of readily available information and inventory of all water fixtures, equipment, and systems and provide guidance on the following: • Set and track towards performance goals • Keep water data updated in ENERGY STAR Portfolio Manager • Fix identified leaks • Install or retrofit existing fixtures for ultra-low-flow models where possible • Ensure best practices for water conservation • Engage and educate tenants on opportunities for specifications and behaviors to drive water efficiency • Continue to research, pilot, and implement strategic water management technologies and strategies in base building and tenant spaces

WASTE We commit to minimize waste generated at our properties through waste reduction, recycling, composting, donation, and other initiatives to divert waste from landfills. Our Sustainable Waste Management Policy outlines the necessary steps for implementation, with responsibilities delegated to our property managers, project managers, custodial staff, tenants, and any third-party waste vendors to improve waste diversion. We place clearly labeled accessible bins for trash, paper, and combined plastic, metal, and glass recycling at all of our assets and loading docks and comply with applicable local Codes and regulations. The installation of waste decals from the Business Integrity Commission (BIC) at our New York City properties provides an opportunity for us to identify single stream or separated recycling to assist building occupants and maintenance. We provide an array of education and engagement programs for our tenants on topics which include recycling, composting, donation programs, and special diversion of regulated waste such as lamps, batteries, and electronic waste. We deploy proactive practical waste diversion strategies that meet or exceed local regulations. We provide training and set best practices and standards for our employees and outside contractor teams to reduce overall waste generation and increase diversion rates. We identify opportunities to track and report waste at each property to ensure that all waste is being collected and diverted in accordance with ESRT’s guidelines. • We commit to perform waste audits at 100% of our buildings to understand waste performance and identify opportunities for improvement. • Waste audits were not completed in 2020 due to low occupancy. Waste audits were completed at each building in 2021 when occupancy reached levels sufficient for impactful results. • We have implemented pilot compost programs with some of our largest tenants and offer furniture reuse and donation programs, and electronic waste collection opportunities.

INTRODUCTION

High-Performance Healthy Buildings

ESRT is committed to provide tenants with healthy work environments focused on the health and wellness of the people who occupy our buildings every day. Healthy buildings where we can work together and collaborate help to restore company culture after widespread office closures, increase productivity, and drive the bottom line. ESRT developed a program of strategies rolled out across the portfolio, in alignment with the Fitwel Certification (83% of NYC portfolio certified), WELL-Health Safety Rating (100% of portfolio certified) and industry-leading best practice. These strategies are illustrated in the figure to the right. INDOOR ENVIRONMENTAL QUALITY (IEQ) For more than a decade, improving IEQ has been a key tenet of our sustainability strategy. Our industry-leading, comprehensive, and state-of-the-art program focuses on operational best practices to ensure healthy and productive spaces, including MERV 13 filters, bipolar ionization air purification technology, indoor air quality (IAQ) testing, CO 2 sensors, green cleaning practices, integrated pest management strategies, and low-emitting materials. In 2020, ESRT was the first commercial real estate portfolio in the Americas to achieve the WELL Health-Safety Rating across 100% of its portfolio and one of the first to recertify. The WELL Health-Safety Rating, developed by the International WELL Building Institute, is an evidence based, third-party rating focused on operational policies, maintenance protocols, emergency plans, and stakeholder education to address a post-COVID-19 environment and broader health and safety-related issues in the future. When faced with the most intense pandemic in over a century, ESRT developed a pathway for our employees, visitors, and tenants to return to the office with confidence. We are partners with the WELL Living Lab and Mayo Clinic to advance the study of the indoor environment’s impact on human health and to help develop practices that can be implemented across the country. ESRT is part of the WELL Living Lab Alliance, a global consortium of organizations that support the advancement of knowledge of IEQ to improve human health and well-being. Our engagement in this effort will extend the WELL Living Lab’s pioneering research at the intersection of health, building, and behavioral sciences. Through our partnership with Delos and WELL Living Lab, a company dedicated to the scientific research, evaluation, and solutions surrounding IEQ impacts on building occupants’ health and well-being, we help the industry provide guidance that our tenants can depend on to promote functional, energy-efficient, and human health–enhancing spaces. We continue to monitor and track performance as science, data, and knowledge evolve.
