GREENHOUSE GAS (GHG) EMISSIONS INVENTORY

AMERICAN SAVINGS BANK GHG INVENTORY (MT CO 2 e)

Given how central climate impact is to our state and our strategies, we understand the importance of measuring and reporting on our GHG emissions. We completed our first detailed emissions inventory in 2022 and continue working with experienced advisors to calculate and disclose our emissions in line with global and industry standards. This year, we’ve built upon our initial inventory by expanding coverage of Scope 3 categories. The GHG emissions inventory captures the types of emissions listed in the table below over the last three years (relative to a 2015 baseline, the earliest year for which we have a complete enterprise-wide inventory). Net GHG emissions in measured categories decreased 19.2% from 2015 to 2022, driven largely by our consolidation of office spaces and branches.

Totals 5,865 Note: Figures have been developed in partnership with an experienced GHG emissions advisor, and should be considered preliminary and subject to future verification. Certain totals for 2015, 2020, and 2021 have been revised slightly from previous disclosures to reflect considerations including: use of the Global Warming Potentials in the UN Intergovernmental Panel on Climate Change’s 4th Assessment Report consistent with regulatory reporting and addition of select Scope 3 categories. 1 Fuel consumption data was used to estimate CO 2 emissions, vehicle mileage data was used to estimate CH 4 and N 2 O emissions. 2 Associated emissions were calculated per Greenhouse Gas Protocol guidance, estimating an upper bound refrigerant leakage rate that is 10% of the total HVAC unit capacity. Office square footage was also used to estimate HVAC capacity. Scope 2 fugitive emissions include emissions from HVAC units not owned or controlled (generally leased facilities). 3 Associated emissions were calculated per EPA guidance using office space electricity consumption and EPA region-specific emissions factors. Location-based method. 4 Spend-based method in which business travel spend is used to estimate emissions. 5 Data for 2021 and earlier is based on average (national) data on commuting patterns, adjusting for remote work percentages. 2022 data was calculated using Hawaii-specific commuting patterns. This Hawaii-specific data was derived by calculating estimated commute distances of 1,000+ employees, based on anonymized ZIP codes. 7,260 6,410 6,103
