Total CO2 Equivalent vs CO2 Emissions
Formel
## How to Calculate Greenhouse Gas Equivalents Different greenhouse gases have different warming potentials. Converting to CO2-equivalent (CO2e) allows comparison. ### Global Warming Potentials (GWP-100) - **CO2**: 1x (baseline) - **Methane (CH4)**: 28x - **Nitrous Oxide (N2O)**: 265x ### Formula **Total CO2e = CO2 + (CH4 * 28) + (N2O * 265)**
Lösungsbeispiel
A facility emits 100 tons CO2, 5 tons CH4, and 1 ton N2O per year.
- 01CO2 contribution: 100 metric tons CO2e
- 02Methane: 5 * 28 = 140 metric tons CO2e
- 03Nitrous oxide: 1 * 265 = 265 metric tons CO2e
- 04Total: 100 + 140 + 265 = 505 metric tons CO2e
- 05Non-CO2 share: (140 + 265) / 505 * 100 = 80.2%
Häufig Gestellte Fragen
What are the main greenhouse gases?
The primary greenhouse gases are carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and fluorinated gases. CO2 accounts for about 76% of global emissions by weight but less when adjusted for potency.
Why is N2O so potent?
Nitrous oxide has 265 times the warming potential of CO2 over 100 years and persists in the atmosphere for about 114 years. Major sources include agriculture, industry, and fuel combustion.
What does CO2e mean?
CO2-equivalent (CO2e) is a standard metric that converts all greenhouse gases to the equivalent amount of CO2 with the same warming effect, enabling comparison across different gases.
