Average Food Consumption for Comparisons
Understanding whether a food product is better or worse than average requires establishing a reliable baseline. This page explains how we calculate the current population consumption statistic used for all comparisons.
Why Averages Matter
Certain metrics for food products we consume, such as:
- CO₂ emissions
- Water scarcity rating
- Rainforest impact
- Animal welfare score
...are only valuable when compared to current population statistics. Only then can we understand:
- If we actually improve the situation
- By how much we improve it
Without this comparison, absolute values lack context and meaning.
Methodology
Data Sources
Our average is calculated from:
- Calculation Database: Millions of environmental assessments performed over the years
- Sales Statistics: Real-world data on meals and products actually consumed
- Frequency Weighting: Acknowledging that some foods are eaten more often than others
Calculation Process
Step 1: Collect all environmental calculations from our database
Step 2: Gather sales statistics for corresponding foods
Step 3: Weight each food by consumption frequency
Step 4: Calculate weighted average across all data
Step 5: Normalize by Daily Food Unit (DFU)
This produces a weighted average that reflects actual eating patterns, not just theoretical food availability.
The Global CO₂/DFU Ratio
Current Value
3894 g CO₂e per 1 DFU
This means that for one Daily Food Unit (representing a day's nutritional needs), the average person causes 3894 grams of CO₂-equivalent emissions.
What is 1 DFU?
One Daily Food Unit contains:
- 2000 kcal (energy)
- 50 g proteins
- 66 g fats
- 2.5 liters water
- 600 g dry mass
See Daily Food Unit (DFU) for detailed explanation.
Interpretation
Any food with a better CO₂/DFU ratio than 3894 g is an improvement.
Example 1: Product with 2000 g CO₂ / 1 DFU
→ Better than average (2000 < 3894)
→ Improvement: 49%
Example 2: Product with 5000 g CO₂ / 1 DFU
→ Worse than average (5000 > 3894)
→ Worse by: 28%
Weighted Averages Explained
Why Weighting Matters
Consider two scenarios:
Unweighted Average (Incorrect):
Food A (rarely eaten): 10,000 g CO₂/DFU
Food B (commonly eaten): 2,000 g CO₂/DFU
Simple average: (10,000 + 2,000) / 2 = 6,000 g CO₂/DFU
Weighted Average (Correct):
Food A (5% of consumption): 10,000 g CO₂/DFU × 0.05 = 500
Food B (95% of consumption): 2,000 g CO₂/DFU × 0.95 = 1,900
Weighted average: 500 + 1,900 = 2,400 g CO₂/DFU
The weighted average (2,400) is much more accurate because it reflects actual eating patterns.
Real-World Application
Our weighted average accounts for:
- Staple foods (rice, bread, potatoes) eaten daily
- Occasional foods (exotic fruits, specialty items) eaten rarely
- Seasonal variations in consumption patterns
- Regional preferences in different markets
- Cultural differences in dietary patterns
Data Quality and Updates

How This Powers Comparisons
Improvement Percentage
The 3894 g baseline enables the Improvement Percentage calculation:
Improvement % = 1 - (Product CO₂/DFU) / 3894
CO₂ Savings
It also enables absolute savings calculations:
CO₂ Savings = (3894 × DFU) - Product CO₂
Climate Friendly Threshold
Products achieving ≥50% improvement (≤1947 g CO₂/DFU) qualify as: ✅ Climate Friendly
This 50% threshold comes from scientific recommendations for necessary emissions reductions.
Related Concepts
Benchmarks
While the global average is 3894 g CO₂/DFU, specific food categories have their own benchmarks:
- Beverages: Lower than average
- Vegetables: Much lower than average
- Poultry: Near average
- Beef: Significantly higher than average
See Benchmark Documentation for category-specific values.
Regional Variations
The global average can be adjusted for:
- Geographic location: European vs. Asian vs. American consumption patterns
- Economic factors: Income levels affect diet composition
- Cultural context: Traditional diets vary significantly
Practical Applications
For Product Developers
Question: Is our new plant-based burger an improvement?
Answer:
- Calculate product CO₂ and DFU
- Compute CO₂/DFU ratio
- Compare to 3894 g baseline
- If under 50% of baseline (1947 g): Climate Friendly ✅
For Restaurants
Question: How does our menu compare to average dining?
Answer:
- Calculate weighted average of all menu items
- Weight by popularity (sales frequency)
- Compare to 3894 g CO₂/DFU baseline
- Identify high-impact items for optimization
For Consumers
Question: Is this meal a better choice?
Answer:
- Look for climate-friendly label (≥50% improvement)
- Check environmental rating (A, B, C, D, E)
- Compare similar meals to choose the better option

FAQ
Q: Does the 3894 g value ever change?
A: Yes, it's updated as we collect more data and consumption patterns evolve. Changes are gradual and well-documented.
Q: Is this value the same worldwide?
A: The 3894 g is our global weighted average. Regional variations exist but are typically within 10-20% of this value.
Q: How often is this updated?
A: The baseline is reviewed annually and updated when significant new data becomes available or consumption patterns shift notably.
Q: Can I use this for my own calculations?
A: Yes, 3894 g CO₂e/DFU is our current published baseline. However, for precise product assessments, we recommend using our calculation services which account for all nuances.
Q: How does this compare to other methodologies?
A: Our approach is unique in weighting by actual consumption. Many other baselines use simple averages or recommended diets rather than real-world eating patterns.
