What are some examples of GHG emissions?

Greenhouse gas (GHG) emissions come from many sources, depending on the nature of an organisation's operations. GHGs are released through energy consumption, industrial activities, transportation, and other daily processes, contributing to your company's carbon footprint. 

Understanding where these emissions come from is essential for reducing them. Below are some common examples of how GHG emissions are generated in different types of operations, specifically in office buildings and manufacturing plants.

Example of emissions from an Office Building

In a typical office building, GHG emissions result from various day-to-day operations, including:

• Heating and Cooling: Using heating systems during winter and air conditioning in the summer generates significant amounts of energy. If this energy comes from fossil fuels (such as natural gas or coal), it results in GHG emissions.

• Electricity Usage: Office equipment like computers, printers, lights, and even kitchen appliances require electricity. If this electricity is generated from fossil fuel power plants, it contributes to the carbon footprint of the office.

• Transportation: Employees commuting to and from work also contribute to GHG emissions, whether they drive personal vehicles, take public transport, or carpool. Air travel for business meetings generates substantial emissions.

Managing energy use in buildings and encouraging more sustainable commuting options can help reduce the carbon footprint of office operations.

Example of emissions from a Manufacturing Plants 

A manufacturing plant typically has a higher carbon footprint due to its energy-intensive operations. Some key examples of GHG emissions in a manufacturing setting include:

• Energy Consumption: Machinery, production lines, and equipment used in manufacturing often require large amounts of energy. If this energy comes from burning fossil fuels, it results in significant GHG emissions. Factories that use renewable energy or increase energy efficiency can reduce their carbon footprint.
  

• Raw Material Production: The extraction and processing of raw materials, such as metals, plastics, or chemicals, are often energy-intensive and result in emissions. For example, mining raw materials like iron or producing chemicals can involve complex processes that emit CO₂ and other greenhouse gases.

• Transportation of Goods: Once products are manufactured, they are transported to customers or distributors. If this transportation relies on fossil-fuel-powered trucks, ships, or airplanes, it contributes to a company’s overall carbon footprint.
  

Manufacturing plants can reduce their emissions by improving energy efficiency, switching to low-carbon energy sources, and optimizing logistics and supply chain processes.
