Stanford is expecting to achieve 80% reduction in emissions from campus operations by 2022 when a new solar facility comes online. Now, Stanford is beginning to measure Scope 3 emissions, the indirect emissions from such things as growing and transporting food, travel, investments and producing the goods we buy. Sally Benson, professor of energy resources engineering and graduate student, Rebecca Grekin, are working on a tool to make quantifying Scope 3 emissions easier.
