GHG Emissions Data CodeGreen has reviewed applicable data and worked with ESRT to prepare a GHG inventory following GHG Protocol Corporate Account and Reporting Standard: Revised Edition guidelines. CodeGreen reviewed energy consumption data utilizing ENERGY STAR Portfolio Manager data and reported tenant sub-meter data to ensure proper allocation of fuel, district steam and base building electricity, tenant submeter and tenant direct-meter emissions across Scope 1, 2, and 3 GHG emissions in alignment with the GHG Protocol. Scope 1 emissions are classified as direct GHG emissions resulting from fuel oil and natural gas. Scope 2 emissions are classified as indirect emissions including electricity and district steam. Scope 3 emissions are classified as indirect emissions resulting from tenant direct and submetered energy consumption. Emissions factors and Global Warming Potentials were also verified. Based on CodeGreen’s Limited Assurance review, there is no evidence indicating that GHG data submitted in public disclosures is not accurate and complete. Water Consumption Data CodeGreen has reviewed applicable water data in ENERGY STAR Portfolio Manager against utility invoices and worked with ESRT to calculate absolute water consumption data for the portfolio of assets. Based on CodeGreen’s Limited Assurance review, there is no evidence indicating that water data submitted in public disclosures is not accurate and complete. Exclusions CodeGreen has excluded the following energy meters from the Limited Assurance review, as utility invoices were unavailable for: Empire State Building Tenant Meters including Walgreens and Starbucks electric.

The emissions were calculated in a consistent and transparent manner and were found to be a fair and accurate representation of the Empire State Realty Trust’s actual usage and were free from material misstatement. CodeGreen has verified a total of: • 39,856 metric tons of CO2 equivalent (CO 2 e) emissions • 157,898 MWh of energy consumption • 318,388 cubic meters of water consumption Based on the processes and procedures conducted, there is no evidence that the GHG statement: • Is not materially correct • Is not a fair representation of the GHG data • Has not been prepared in accordance with the Greenhouse Gas Protocol
