ESB 2023 Performance and Projections
As of 2023, ESB has reduced CO2e emissions by 13.0% compared 2019 baseline and 57.1% compared to 2007 baseline. Utilizing 2023 operation and expected ESRT2.0 projects, the building is expected to meet its LL97 2030 Limit, LL97 2035 Limit, and 80x30 Target.
2009 Emissions – The 2009 building CO2e emissions utilizing 2009 utility rates and 2009 eGRID emission factors. BAU (Static Grid) – The 2019-present building CO2e emissions without ESRT2.0 project integration. Future years utilize a constant, 2023 electrical grid coefficient projection. Actual Emissions (CLCPA) – Actual building emissions from 2019-present. Projected Emissions (CLCPA) – Future CO2e emission projections based on the planned ESRT2.0 projects. Future years utilize CLCPA projections for electrical grid coefficients.
LL97 2030 Limit – The LL97 building CO2e emission limit required to be met by 2030 to avoid fines. LL97 2035 Limit – The LL97 building CO2e emission limit required to be met by 2035 to avoid fines. 80x30 Target – The building CO2e emission target to achieve an 80% CO2e emission reduction from the 2007 baseline.
