Recycling CO₂ Savings Calculator

Estimate CO₂ saved by recycling.

Material recycled per year

CO₂ saved per kg

Calculated Output

CO₂ saved/year 200

CO₂ saved/year (tonnes) 0.2

Formula: CO₂ saved = kg recycled × CO₂ saved per kg

Step-by-Step Breakdown

1. Values used:

2. Material recycled per year = 200

3. CO₂ saved per kg = 1

5. CO₂ saved/year = Material recycled per year x CO₂ saved per kg = 200 x 1 = 200

6. CO₂ saved/year = 0.2tonnes

The math behind it

CO₂ saved = kg recycled × CO₂ saved per kg. Paper ~1, aluminium ~9, plastic ~1.5 kg CO₂ per kg.

200 kg at 1 kg CO₂/kg → 200 kg CO₂/year.

Aluminium?

Recycling aluminium saves the most — ~9 kg CO₂ per kg.
