Oregon historical2023 electricity-generation emissions
EPA eGRID2023 revision2 state electricity-generation emissions context,ST23 worksheet. Historical2023,not current2026 conditions or data center facility emissions. Annual NOx,SO2 andCO2 totals in source tons are distinct from source-reported total output rates in lb/MWh;CO2 is not CO2 equivalent. Annual net generation is MWh,not installed capacity or customer use. Rates are not marginal emissions,ambient concentrations,health effects or emissions factors allocated to a data center. No tons-to-tonnes conversion,rate recomputation,facility join or causal data center inference. State generation context does not establish the mix delivered to consumers. Puerto Rico source row is outside this51state/DC review,not absence.

Oregon historical power and useful thermal emissions2025 and2024
EIA Table9.5 historical state2025 and2024 emissions estimates from energy consumption at conventional power and combined-heat-and-power plants. Includes electricity generation AND production of useful thermal output,not electricity-only emissions. Source unit is thousand metric tons,not eGRID source tons,pounds,CO2equivalent or emission intensity. Source CO2,SO2 and NOx are distinct pollutants,not summed as one climate measure. Displayed zero values may represent small values rounded to zero;no absence or zero-emissions certification. Retain displayed HTML precision;source says Excel cells provide additional precision,not adopted here. No direct eGRID trend or data center allocation,marginal emissions,ambient concentration,health risk,permit compliance,current2026 activity or Native facility joins.
