Understanding the Gases That Make Up CO₂e
Understanding the Gases Behind CO₂e
Reducing carbon emissions has become a key priority for UK businesses. Many companies now face growing pressure to show progress on sustainability and meet environmental expectations.
CO₂e goes beyond just carbon dioxide. It includes several gases, each with a different impact on climate. By understanding these gases, you can make better choices when selecting cleaning equipment and products. This guide explains it simply, so your business can take the next step with clarity.

CO₂e stands for carbon dioxide equivalent. It is a way to measure the total impact of different greenhouse gases using one standard unit. This makes it easier to compare emissions and understand their effect on the environment.
Each greenhouse gas traps heat differently. CO₂e converts them into the equivalent amount of carbon dioxide based on how much they warm the atmosphere. For example, one tonne of methane has a much stronger warming effect than one tonne of carbon dioxide, so it is counted as more CO₂e. This approach helps businesses track their environmental impact more accurately.

The Gases Included in CO₂e
CO₂e includes more than just carbon dioxide. It also accounts for several other gases, each with a higher warming effect. These gases are often released during industrial, agricultural, or energy-related processes.
Understanding these gases helps your business make better decisions when choosing cleaning products, equipment, and suppliers. Below is a simple breakdown of the main gases included in CO₂e.
1. Carbon Dioxide (CO₂)
Where it comes from: Fuel use, heating systems, vehicle emissions
Why it matters: Most common and long-lasting greenhouse gas
Impact: Used as the baseline for all other gases
2. Methane (CH₄)
Where it comes from: Landfills, agriculture, gas leaks
Why it matters: Traps more heat than CO₂
Impact: Around 28 to 36 times more potent than CO₂ over 100 years
3. Nitrous Oxide (N₂O)
Where it comes from: Fertilisers, waste, manufacturing
Why it matters: Strong warming effect, long life in atmosphere
Impact: Nearly 265 times more powerful than CO₂
4. F-Gases (e.g. HFCs, PFCs, SF₆, NF₃)
Where they come from: Refrigeration, electronics, specialist cleaning tools
Why they matter: Extremely high global warming potential
Impact: Some are thousands of times more damaging than CO₂
CO₂ vs CO: Know the Difference
Carbon dioxide (CO₂) and carbon monoxide (CO) are often confused, but they are very different gases. Both are colourless and odourless, yet their roles and risks are not the same.
CO₂ contributes to climate change by trapping heat in the atmosphere. It is a major greenhouse gas and forms the base unit for measuring CO₂e. CO, on the other hand, is not a greenhouse gas. It is toxic and dangerous to human health, especially in enclosed spaces, but it does not have the same environmental impact as CO₂.

CO₂e Reporting and Why It Matters for UK Businesses
Many UK businesses must measure and report their CO₂e emissions as part of environmental regulations and sustainability goals. Reporting helps companies understand their total greenhouse gas impact and identify areas to reduce emissions.
CO₂e reporting covers emissions from energy use, transport, waste, and purchased goods, including cleaning products and equipment. Accurate data supports better decisions and boosts your company’s reputation for workplace hygiene and environmental compliance.

Key Takeaways
CO₂e measures the combined impact of several greenhouse gases, helping businesses understand their true carbon footprint.
Carbon dioxide (CO₂) is the main greenhouse gas, but methane, nitrous oxide, and F-gases also contribute significantly.
Carbon monoxide (CO) is very different from CO₂. It is harmful to health but does not drive climate change.
Accurate CO₂e reporting supports better environmental decisions and strengthens your company’s sustainability credentials.
Choosing eco-friendly cleaning equipment and products reduces emissions and improves workplace hygiene.
