Background of emission factor

Natural gas is a fossil fuel widely used in energy production, transportation, and industry. It consists primarily of methane, which is a potent greenhouse gas. The emission factor of natural gas indicates how much carbon dioxide is released per unit of energy produced from its combustion. Potential methane leaks from natural gas are particularly harmful to the climate.

Emission factor category

The emission factor for fuels shows how much emissions are caused by burning the fuel. Carbon dioxide emissions occur when the carbon in the fuel combines with oxygen during combustion. Most global greenhouse gas emissions are caused by burning fossil fuels (coal, natural gas and oil)

Quality of emission factor

High-quality emission factors verified by an external verifier, usually sourced directly from the supplier (primary data). The factor may be a maximum of 3-5 years old and cover all greenhouse gases (CO2e).

Unverified primary data factors, as well as new and accurate average factors based on physical quantities. The factor may be a maximum of 3-5 years old.

Average, based on physical quantities, with one of the following shortcomings: more than 5 years old, only CO2 emissions, or contains many assumptions.

Inaccurate emission factors based on physical quantities that contain several of the following shortcomings: more than 5 years old, only CO2, or contains many assumptions. The newest, highest-quality spend-based emission coefficients also fall into this category.

Old and inaccurate spend-based emission factors. Their use in emission calculations should be avoided.
