California State Teachers Retirement System

The California State Teachers Retirement System (CalSTRS), based in the US and operating in the "Other services (93)" industry, has established significant climate commitments. For the reporting year 2023, CalSTRS reported Scope 2 emissions from purchased electricity amounting to approximately 923,000 kg CO2e, and Scope 1 and 2 combined emissions of approximately 239,000 kg CO2e. In 2022, Scope 2 emissions were about 977,000 kg CO2e, with combined Scope 1 and 2 emissions at approximately 366,000 kg CO2e. The previous year, 2021, saw Scope 2 emissions of about 864,000 kg CO2e, and combined Scope 1 and 2 emissions totalling approximately 374,000 kg CO2e.

Looking further back, in 2017, CalSTRS reported total emissions of approximately 2,132,000 kg CO2e, comprising Scope 1 emissions of about 205,000 kg CO2e, Scope 2 emissions of approximately 1,419,000 kg CO2e, and Scope 3 emissions (specifically business travel) of about 821,000 kg CO2e. In 2016, total emissions were approximately 2,238,000 kg CO2e, with Scope 1 at about 244,000 kg CO2e, Scope 2 at around 1,994,000 kg CO2e, and Scope 3 (business travel) at approximately 774,000 kg CO2e. In 2015, total emissions were approximately 2,135,000 kg CO2e, with Scope 1 emissions around 238,000 kg CO2e, Scope 2 at approximately 1,897,000 kg CO2e, and Scope 3 (business travel) at about 777,000 kg CO2e.

CalSTRS is committed to achieving net-zero emissions from its operations by 1 January 2035, or as soon as possible thereafter, in compliance with California Senate Bill 1203. This commitment applies to Scope 1 and Scope 2 emissions. Previously, CalSTRS had set a target for overall reduction by 2020, aiming for a 30% reduction in Scope 1 emissions and a 16% reduction in Scope 2 emissions from a 2015 baseline. They continue to seek opportunities to reduce their enterprise greenhouse gas emissions.
