What is the Carbon Footprint Calculator?
A carbon footprint calculator converts your energy use into CO₂ emissions using standard emission factors.
How to Calculate
CO₂ = electricity × 0.71 + petrol/diesel × 2.31 + LPG × 2.98 (kg). We annualise it and divide by ~21 kg (a tree's yearly absorption).
Formula
CO₂ = Σ (usage × emission factor)
