GHG Metric

Carbon offsets using GHG-metrics are measured in metric tons of carbon dioxide equivalent (CO₂e) and may represent primary categories of greenhouse gases:

1. Carbon Dioxide (CO₂)
2. Methane (CH₄)
3. Nitrous Oxide (N₂O)
4. Sulfur Hexafluoride (SF₆)
5. Hydrofluorocarbons (HFC_s)
6. Perfluorocarbons (PFC_s) and
7. Nitrogen Trifluoride (NF₃).

In the context of the economic structure in Saudi Arabia, Methane (CH₄) emissions related to oil production are addressed, Perfluorocarbons (PFC_s) are relevant in aluminum production, Nitrous Oxide (N₂O) emissions in the chemical industry (e.g., nitric acid production), and Sulfur Hexafluoride (SF₆) for operating electricity grids. Finally, HFC_s are relevant in the cooling sector (HVAC systems and AC units), NF₃ are relevant in some high-tech industries, including in the manufacture of many electronics.
