Carbon Emissions Data

Snohomish PUD is proud to be a leader in providing environmentally responsible electricity. To aid customers in their calculation of their carbon footprints, the PUD provides calculations of the carbon content (or emissions factor) of their electricity using Washington state’s Fuel Mix Disclosure filing, and the Washington State Department of Ecology’s method for using that filing, to measure greenhouse gas emissions. More information on how this is done, and the math behind it is available in the documents to the right.

Snohomish PUD’s Metric Tons (MT) of CO2 equivalent per megawatt-hour* (MWh) for 2019 was .0215 – or less than 5% of the national average.


*One MWh is equal to 1,000 kilowatt-hours (kWh)
