The purpose of this study is to help improve understanding of the scale and sources of fugitive methane emissions (i.e., small unintentional gas leaks) from California’s commercial buildings.

The study seeks to conduct 100+ on-site leak detection tests and receive 300+ survey responses from the following building sectors: office buildings, lodging/hotels, schools/education, healthcare, retail, food, and warehouses.
