Greenhouse Gas Protocol methodology for oil-fired electricity



This methodology represents CO2 emissions associated with the oil-fired production of grid electricity in specific countries and other international jurisdictions. The data is sourced from the Greenhouse Gas Protocol worksheet for GHG emissions from purchased electricity (Version 2.1; published June 2009), based on data published by the International Energy Agency IEA.

The methodology

Emissions model

Electricity is produced by a variety of energy sources, including fossil fuel combustion (coal, natural gas, oil), nuclear fission, and renewable sources (e.g. hydro, wind, solar). These sources produce greenhouse gases and other pollutants to differing extents. This methodology represents greenhouse gas emissions associated with oil-fired power-generation specifically.

The methodology is based upon emissions factors which represent the rate at which emissions occur in relation to quantities of electricity generated. Multiplying a quantity of electricity generated by these emissions factors results in an estimate of the emissions associated with that quantity.

Model data

The emissions intensity of oil-fired plants varies by geographic region. 130 distinct countries and other international jurisdictions are described by time-series of historical annual emissions factors for CO2 (2000-2006).

Activity data required

The quantity of electricity generated is required to make a calculation.

Calculation and result

The quantity returned represents the CO2 emissions associated with the country/region and energy quantity specified.
