Category Comparisons in Reports
On page three of our PDF reports, we break down a restaurant's monthly emissions into various food categories, such as "plant-based" or "animal-based" ingredients. This provides detailed insights into which types of ingredients contribute most to environmental impact.
What We Display
For each food category, the report shows:
- Weight (kg): Total weight of ingredients in this category
- Total CO₂ emissions (kg): Combined emissions from all ingredients in the category
- Comparison to all restaurants: How this restaurant's category emissions compare to the average
How the Comparison Works
Normalization Process
The comparison is made by averaging the CO₂ values of each category across all restaurants in our database. To ensure fair comparison, each restaurant is normalized to the same size as your establishment.
Normalization method: Daily Food Unit (DFU)
This ensures that:
- Small cafes aren't unfairly compared to large hotel restaurants
- Seasonal variations in guest numbers are accounted for
- Different service styles (buffet vs. à la carte) are fairly represented
Calculation Steps
- Collect category data from all restaurants
- Normalize each restaurant to the same number of Daily Food Units
- Calculate average CO₂ per category
- Compare your restaurant to this normalized average
Example Categories
Common categories include:
- Plant-based: Vegetables, fruits, grains, legumes
- Animal-based: All meat, fish, dairy, eggs
- Beef: Specifically beef products
- Chicken: Specifically chicken products
- Pork: Specifically pork products
- Fish: All fish and seafood
- Dairy: Milk, cheese, yogurt, cream
- Beverages: Tea, coffee, juices
- Processed: Packaged and processed foods
Interpreting the Results
Understanding Relative Emissions
A climate-friendly restaurant that serves meat might choose to purchase more chicken than beef. This strategic choice means:
- ✅ Overall emissions are lower (chicken < beef)
- ⚠️ The "chicken" category shows relatively higher emissions
- ✅ The "beef" category shows relatively lower emissions
This is expected and positive - it reflects conscious environmental choices.
Example Scenario
Restaurant Profile: Climate-conscious establishment
Tea Category Analysis:
- Observation: Purchased more tea leaves than average restaurant
- Category emissions: Slightly above average for tea
- Overall impact: Negligible (tea has very low total emissions)
- Assessment: Not a concern - total emissions from tea are minimal
Interpretation: Even if certain low-impact categories are above average, the total environmental impact remains small. Focus optimization efforts on high-impact categories.
Strategic Insights
High-Impact Categories
Focus improvement efforts on categories with:
- High total emissions (kg CO₂)
- Large quantities purchased (kg)
- Above-average comparison to other restaurants
Priority for reduction: Beef, dairy, lamb (highest impact per kg)
Low-Impact Categories
Categories with low total emissions can exceed average without concern:
- Tea and coffee (minimal impact)
- Herbs and spices (small quantities)
- Most vegetables (inherently low emissions)
Guideline: Even 2x average in low-impact categories has less impact than small increases in beef consumption.
Use Cases
Menu Planning
Identify optimization opportunities:
Category: Beef
Your emissions: 150 kg CO₂/month
Average: 100 kg CO₂/month
Status: 50% above average
Action: Reduce beef portions or frequency
Celebrate successes:
Category: Plant-based
Your emissions: 80 kg CO₂/month
Average: 120 kg CO₂/month
Status: 33% below average
Action: Highlight on menu as climate-friendly strength
Procurement Decisions
Compare supplier options within categories:
- Different beef cuts and sources
- Organic vs. conventional dairy
- Local vs. imported produce (seasonal impact)
Guest Communication
Demonstrate environmental leadership:
- "Our plant-based options are 40% below industry average"
- "We've reduced beef emissions by 60% through careful sourcing"
- "Seasonal vegetables keep our produce emissions 30% lower"
Report Visualization
Reports typically show:
Bar charts comparing your restaurant (colored bar) to average (baseline)
- Bars extending right: Above average emissions
- Bars extending left: Below average emissions
- Color coding: Red (high), Yellow (medium), Green (low)
Data tables with detailed breakdowns:
- Category name
- Total weight (kg)
- Total emissions (kg CO₂)
- Comparison percentage vs. average
Limitations and Context
Important Considerations
-
Category breadth: Broad categories (e.g., "plant-based") may hide variation in specific ingredients
-
Seasonal effects: Some categories naturally vary by season (e.g., heating energy for greenhouses)
-
Regional differences: Local food availability affects what's considered "average"
-
Service style: Buffet vs. plated service affects waste and portions
Future Improvements
Our models continue to evolve to provide:
- More granular category breakdowns
- Regional and seasonal adjustments
- Specific cultivation method differentiation
- Transportation route specificity
- Greenhouse usage duration tracking

Taking Action
Recommended Process
- Review report - Identify categories above average
- Prioritize - Focus on high-emission, high-volume categories
- Research alternatives - Find lower-impact substitutes
- Test changes - Implement gradually with guest feedback
- Monitor progress - Track improvements in next month's report
Example Action Plan
High Priority (Beef category 50% above average):
- Reduce portion sizes by 20%
- Offer plant-based alternative for every beef dish
- Switch to grass-fed beef (typically lower emissions)
- Reduce menu items featuring beef
Medium Priority (Dairy category 30% above average):
- Offer plant-based milk alternatives
- Use precision portioning for cheese
- Source from regenerative dairy farms
Celebrate (Plant-based category 40% below average):
- Feature prominently on menu
- Train staff to recommend these dishes
- Marketing: "Award-winning climate-friendly options"
FAQ
Q: Why is my chicken category high if chicken is climate-friendly?
A: If you've successfully reduced beef consumption, chicken becomes a larger proportion of your meat purchases. This is expected and positive - you're choosing lower-impact proteins.
Q: Should I worry about being above average in vegetables?
A: Generally no. Even significantly above-average vegetable consumption has minimal environmental impact compared to animal products. Focus on high-impact categories.
Q: How often should categories be reviewed?
A: Monthly reviews align with our reporting cycle. This allows tracking seasonal changes and measuring impact of menu adjustments.
Q: Can I get more specific subcategories?
A: Yes, detailed reports can break down major categories further. Contact your Eaternity account manager for customized reporting.
