Greenhouse Gas Emissions - Explained

Many people and organisations know that they need to record and report on their emissions but what measurement do you need to go against? GHG emissions factors are the standard that is used but what are they?

Greenhouse gas (GHG) emission factors are values used to estimate the amount of GHG emissions associated with a particular activity or process. They are usually expressed as the amount of GHG emissions per unit of activity, such as per kilometre travelled, per unit of electricity consumed, or per ton of waste disposed of.

GHG emission factors vary depending on the activity or process being measured and the specific sources of emissions involved. For example, the GHG emission factor for electricity generation will depend on the fuel source used, such as coal, natural gas, or renewables. Similarly, the GHG emission factor for transportation will depend on the type of vehicle and fuel used, as well as factors such as speed, traffic, and road conditions.

GHG emission factors are used to calculate a company's or individual's carbon footprint, which is the total amount of GHG emissions associated with their activities or operations. Carbon footprints can be used as a tool to identify opportunities for emissions reductions and to track progress towards climate goals.

GHG emission factors are often published by government agencies, industry associations, and non-governmental organizations. They may be used by businesses, governments, and individuals to assess and manage their carbon footprint and to inform decisions related to energy use, transportation, waste management, and other activities that contribute to GHG emissions.
