* Marginal Electricity Emission Factor (current) calculates greenhouse gas emissions based on the marginal increase to electricity production based on new electricity demand. It assumes that all new electricity supply is 50 percent greenhouse gas-neutral and 50 percent from a combined cycle gas turbine.

**Average Electricity Emission Factor calculates greenhouse gas emissions based on the average actual emission factor for BC Hydro from the past five years (direct and indirect emissions).

***Marginal Electricity Emission Factor (proposed) assumes 2007 Speech from the Throne targets of no net greenhouse gas emissions from new sources by 2016 is implemented.
