EMPIRE STATE REALTY TRUST: 2021 SUSTAINABILITY REPORT
We target accomplishment of an 80% reduction of operational carbon from the 2007 baseline with a payback against investment of 5-7 years or better. We will offset any remaining carbon emissions for which total carbon reduction is not technically or economically feasible on site. As demonstrated in the static grid line graph below, none of the modeled packages will achieve an 80% emissions reduction or compliance with LL97 limits without work by the city to improve the grid, highlighting the challenge to achieve carbon neutrality or compliance with LL97 with a static New York City grid. The CLCPA grid scenario graph illustrates that all packages ensure the Empire State Building achieves an 80% reduction from baseline and three of the five packages project compliance with LL97 long term 2035-2050 emissions limits. At this time, ESRT plans to move forward with select measures from the package known as “CO 2 mid” which projects an 88% emissions reduction based on the projected performance of projects and a CLCPA compliant grid with a 6.8 year payback or less. ESRT will annually report progress against our goals in the Sustainability Report to document completed projects, savings (financial and emissions), and new technologies we have successfully deployed. We will continue to share adjustments to our process and lessons learned with the real estate community through our reporting and through updates to the playbook.

PROJECTED ANNUAL CARBON EMISSIONS
STATIC 2019 GRID SCENARIO No packages would meet 80% reduction from 2007 baseline by 2035; No packages would meet average long-term LL97 limit
CLCPA GRID SCENARIO All packages would meet 80% reduction 2007 baseline by 2030; Only CO 2 Mid package would meet average long-term LL97 limit
