Meat-Free Days Savings Calculator

Find CO₂ saved by cutting beef days.

Meat-free days per week

Beef avoided per day

CO₂ per kg beef

Calculated Output

CO₂ saved/year 280.8

CO₂ saved/year (tonnes) 0.2808

Formula: CO₂ saved = days/week × 52 × beef kg × CO₂/kg

Step-by-Step Breakdown

1. Values used:

2. Meat-free days per week = 2

3. Beef avoided per day = 0.1

4. CO₂ per kg beef = 27

6. CO₂ saved/year = 280.8

7. CO₂ saved/year = 0.2808tonnes

Did this calculator solve your problem today?

The math behind it

CO₂ saved = meat-free days/week × 52 × beef avoided per day × 27 kg CO₂ per kg beef.

2 days/week, 0.1 kg → ~281 kg CO₂/year.
