Washington Governor Christine Gregoire (D) has signed a bill (S.B. 6373) that will align the state’s greenhouse gas (GHG) reporting requirements with the Environmental Protection Agency’s (EPA’s) reporting rules, although the state law is somewhat more stringent than federal rules. For example, EPA requires annual reporting for fuel suppliers and facilities that emit 25,000 metric tons of GHGs per year, whereas the Washington law requires reporting by facilities that emit 10,000 metric tons.
