1. What is Meat Carbon Footprint?

The meat carbon footprint measures the greenhouse gas emissions (CO2 equivalent) produced throughout the lifecycle of meat production, from farm to table. Different types of meat have significantly different environmental impacts.

2. How Does the Calculator Work?

The calculator uses the following equation:

Where:

• \( CO2e \) — Carbon dioxide equivalent emissions
• \( Amount \) — Weight of meat consumed (kg)
• \( Factor \) — Emission factor specific to meat type (kg CO2e/kg)

Typical Emission Factors:

• Beef: 26.5 kg CO2e/kg
• Lamb: 25.0 kg CO2e/kg
• Pork: 6.4 kg CO2e/kg
• Chicken: 3.7 kg CO2e/kg

3. Importance of Meat Footprint Calculation

Details: Understanding the carbon footprint of different meats helps consumers make environmentally conscious dietary choices and reduce their overall climate impact.

4. Using the Calculator

Tips: Enter the amount of meat consumed in kilograms and select the type of meat. The calculator will estimate the associated carbon emissions.

5. Frequently Asked Questions (FAQ)

Q1: Why does beef have such a high footprint?
A: Beef production requires large amounts of feed, land, and water, and cattle produce methane - a potent greenhouse gas.

Q2: Are these values for cooked or raw meat?
A: These factors are for raw meat. Cooking may add additional emissions depending on energy source.

Q3: How does meat compare to plant-based proteins?
A: Plant proteins typically have much lower footprints (e.g., lentils ~0.9 kg CO2e/kg, tofu ~2.0 kg CO2e/kg).

Q4: Does production method affect the footprint?
A: Yes, grass-fed beef may have higher emissions than grain-fed due to longer growth periods, though land use differs.

Q5: What about processed meats?
A: Processed meats have slightly higher footprints due to additional energy used in processing and packaging.
