🌍 Overview: Calculate Your Carbon Footprint
The CO₂ Emission Calculator estimates how much carbon dioxide is released by your daily activities, such as:
- 🚗 Driving personal or company vehicles
- ⚡ Consuming electricity or energy from various sources
- 💡 Using custom emissions data for accurate results
The tool supports two modes:
- Driving Mode: Input your trip distance and CO₂ emissions per km
- Energy Mode: Input energy consumed (in kWh) and select a known emission factor or enter your own
You’ll also see how many trees are required to absorb that carbon output annually.
📘 Based on IPCC 2014 Guidelines and global forestry offset averages.
🧮 Formula & Methodology
The calculator uses two different equations depending on the mode:
- Driving Mode:
CO₂ Emissions (g) = Distance (km) × Emission Factor (g/km) - Energy Consumption Mode:
CO₂ Emissions (g) = Energy (kWh) × Emission Factor (g/kWh)
The result is converted to kilograms (1 kg = 1000 g), and we estimate how many trees would be required to offset that emission using:
Number of Trees = CO₂ (kg) ÷ 21(Assuming one mature tree absorbs ~21 kg of CO₂ per year.)
📊 Example Calculations
- 🚗 Driving:
Distance = 100 km
Emission Factor = 150 g/km
CO₂ = 100 × 150 = 15,000 g = 15 kg
Trees needed = 15 ÷ 21 ≈ 1 tree - ⚡ Energy Consumption:
Energy = 200 kWh
Emission Factor = 500 g/kWh
CO₂ = 200 × 500 = 100,000 g = 100 kg
Trees needed = 100 ÷ 21 ≈ 5 trees

❓ Frequently Asked Questions
What is a CO₂ emission factor?
It's the average amount of carbon dioxide released per unit of activity—e.g., per kilometer driven or per kilowatt-hour consumed. Emission factors vary by vehicle type, fuel, and electricity source.
Where do the emission values come from?
The calculator uses standard values published by the Intergovernmental Panel on Climate Change (IPCC, 2014). You can also enter custom values.
What types of energy can I select?
The tool includes options for coal, gas, oil, nuclear, solar, wind, hydro, and others. Each energy type has a predefined emission factor.
Can I use my own CO₂ emission rate?
Yes! Simply choose the "Custom" option and enter any emission factor you want in g/km or g/kWh.
How many trees does it take to offset emissions?
A mature tree absorbs about 21 kg of CO₂ per year. We divide your emission result (in kg) by 21 to estimate the offset required.
Does this cover air travel or shipping?
Not directly, but you can use custom emission values (e.g., g/km per passenger) from aviation or logistics providers for a rough estimate.
Is this tool suitable for carbon offset programs?
It provides a quick approximation. For verified offsetting, consult certified carbon footprint auditors or offset platforms.
