We target an 80% reduction of operational carbon emissions from the 2007 baseline with a payback against investment of five to seven years or better. We will offset any residual carbon emissions for which total carbon reduction is not technically or economically feasible on site or poses safety and resiliency risks. As demonstrated in the static grid line graph to the right, 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, which highlights the challenge to achieve net zero or compliance with LL97 with a static New York City grid. The CLCPA grid scenario graph illustrates that all packages ensure that 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, financial and emissions savings, 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 disclosures and updates to the Playbook.
