Conversion Formula:
t CO2e → kg CO2: multiply by 1000.000000
CO₂ vs. CO₂e:
CO₂ (carbon dioxide) refers specifically to carbon dioxide emissions.
CO₂e (carbon dioxide equivalent) encompasses all greenhouse gases converted to the equivalent warming effect of CO₂. This includes methane (CH₄), nitrous oxide (N₂O), and fluorinated gases, which have higher global warming potentials than CO₂.
Carbon Metrics Reference
| Concept | Definition | Units | Example |
|---|---|---|---|
| Carbon Footprint | Total greenhouse gas emissions caused by an individual, event, organization, service, place or product | CO₂e | Average person: ~4.8 tonnes CO₂e/year |
| Carbon Intensity | Amount of carbon emitted per unit of energy or per unit of GDP | g CO₂e/kWh or kg CO₂e/$ | Coal electricity: ~1,000 g CO₂e/kWh |
| Global Warming Potential (GWP) | Measure of how much heat a greenhouse gas traps compared to CO₂ | CO₂e | Methane GWP: 25-28 times CO₂ |
| Carbon Budget | Cumulative amount of carbon emissions permitted to limit global warming to a specific temperature | Gt CO₂e | 1.5°C budget: ~400 Gt CO₂ remaining |

Carbon Offsetting:
Carbon offsetting involves funding projects that reduce or remove carbon emissions to compensate for emissions produced elsewhere. Common approaches include:
- • Renewable energy investments (wind, solar, hydro)
- • Forest conservation and reforestation
- • Carbon capture and storage technologies
- • Methane capture from landfills or agricultural operations
- • Energy efficiency improvements
While offsetting can help mitigate climate impact, the most effective approach is to first reduce emissions as much as possible.
Carbon Footprint Reduction Tips
🏠 At Home
- • Switch to renewable energy providers
- • Improve home insulation and energy efficiency
- • Use energy-efficient appliances and lighting
- • Reduce, reuse, and recycle waste
- • Conserve water (especially hot water)
🚂 Transportation
- • Walk, cycle, or use public transport
- • Consider an electric or hybrid vehicle
- • Carpool when possible
- • Avoid unnecessary air travel
🍽️ Food Choices
- • Reduce meat consumption, especially beef
- • Choose local, seasonal produce
- • Minimize food waste
- • Opt for products with minimal packaging

Common Conversion Formulas
| From | To | Formula |
|---|---|---|
| CO₂ Emissions | kg CO₂ to Metric Tons CO₂ | Metric Tons = kg CO₂ / 1,000 |
| Carbon Dioxide (CO₂) | Carbon (C) | CO₂ = C × 3.67 |
| Driving Emissions | Distance (miles), Fuel Efficiency (mpg) | kg CO₂ = (Distance / MPG) × 8.887 |
| Electricity Emissions | Energy (kWh), Grid Factor (kg CO₂/kWh) | kg CO₂ = kWh × Grid Factor |
