One improved number leaves other questions
A vegetable packing service reports lower electricity per delivered kilogram. That can be a real improvement on its stated basis, yet its total electricity might rise and customers might pay more. A food system has several relevant outcomes; no single resource ratio describes them all.
A trade-off arises when an option improves one relevant outcome while worsening another. Some combinations improve several outcomes together. Begin with the decision and affected people, then choose a compact set of measures that can reveal both possibilities. The purpose is comparison, not a display containing every number the organisation holds.
State the useful output and boundary
For a resource comparison, define the product, function, time and location. A kilogram of packed edible vegetables delivered in usable condition is different from a kilogram entering the warehouse. Product mix, storage duration and service requirements can also change what the denominator means.
Specify which stages are included. A facility electricity meter excludes some upstream production, transport and equipment impacts. An included refrigeration stage must retain its actual operating period. The comparison can still be useful at that limited boundary, provided it is not presented as a complete environmental ranking.
Read the total beside the ratio
In an invented comparison, the same defined packing-service boundary records 800 kWh for 1000 kg delivered in period A, and 900 kWh for 1500 kg in period B. Equivalent delivered product function is stipulated. Electricity intensity is 0.8 kWh/kg in A and 0.6 kWh/kg in B, a 25% decrease. Total electricity rises by 100 kWh, or 12.5%.
Both findings are correct. The lower ratio does not mean lower total demand. It also does not establish the intervention's effect, because the periods may differ in conditions. Nor does it establish emissions, cost or full-system sustainability: those questions require the electricity origin, other resources and relevant outcomes.
| Measure | Period A | Period B |
|---|---|---|
| Delivered product | 1000 kg | 1500 kg |
| Included electricity | 800 kWh | 900 kWh |
| Electricity per delivered mass | 0.8 kWh/kg | 0.6 kWh/kg |
A lower ratio can accompany a larger total
Read the diagram as text
The invented periods change from 800 kWh/1000 kg to 900 kWh/1500 kg. The ratio falls 0.8 to 0.6 kWh/kg while the included electricity total increases.
Parts
- A: 800 kWh / 1000 kg
- 0.8 kWh/kg within the stated service boundary
- B: 900 kWh / 1500 kg
- 0.6 kWh/kg; equivalent delivered function assumed
- Intensity falls 25%
- (0.8 − 0.6) / 0.8; a recorded ratio change
- Total rises 12.5%
- 100 kWh additional facility electricity
Connections
- A: 800 kWh / 1000 kg → Intensity falls 25%: 0.8 kWh/kg
- B: 900 kWh / 1500 kg → Intensity falls 25%: 0.6 kWh/kg
- Intensity falls 25% → Total rises 12.5%: check totals too
Include outcomes that the ratio omits
Pair the resource record with questions about who can obtain the product, its price relative to people's means, and the labour and skills required. An average selling price cannot establish affordability for every household. More output does not demonstrate decent working conditions or equitable access.
Safety and product suitability also need appropriate process evidence. An absent verification record is not a measured zero failure rate. Avoid turning an unresolved safety question into a small negative score that can be cancelled by inexpensive electricity. Detailed hazard controls and their validation remain in the food-safety branch.
A score contains choices
Do not add kilograms, electricity, prices and survey percentages as though they were one physical quantity. A composite score requires a transformation and weighting rule. That rule expresses choices about which outcomes matter and how much compensation between them is allowed; it is not discovered merely by formatting a dashboard.
If a summary is useful, keep the underlying measures, weights, exclusions and data quality accessible. A missing value should remain identifiable, not become a favourable rating. Show important low-performing outcomes explicitly. Uncertainty about a measure and poor performance on that measure are different facts.
Let the evidence guide the next question
A small transparent display can state the measured result and its limit:'Electricity per delivered kilogram fell in these records, total facility demand rose, and upstream emissions and household affordability were not assessed.' It can then identify which missing evidence matters most for the decision.
Agree the reporting period and indicators before judging a change. Retain negative or unexpected findings and consult affected users and workers. Shared system and uncertainty Foundations support the reading; neighbouring topics develop resource accounts, evaluation design and food access. The dashboard should help readers examine evidence rather than force a predetermined winner.
Worked examples
Two electricity conclusions
How do the invented total and per-kilogram electricity records compare?
- Calculate 800/1000=0.8 kWh/kg and 900/1500=0.6 kWh/kg.
- Intensity falls by(0.8−0.6)/0.8×100=25%.
- Total rises by 900−800=100 kWh; 100/800×100=12.5%.
Recorded electricity intensity fell 25%, while included total electricity rose 12.5%. No complete impact or causal ranking follows.
Read a missing safety value
A summary assigns its best safety score because no verification result was entered. Is that justified?
- Distinguish missing evidence from an observed result.
- Identify the process-specific verification required for the claim.
- Display the gap rather than treating it as favourable performance.
No. An absent record does not establish safe output or a zero failure rate; the summary must retain that uncertainty.
Check your understanding
Does lower facility electricity per kilogram establish lower total electricity?
Show answer and reasoning
No.
The denominator can grow faster than total demand, as in the invented example.
Can one price average establish affordability for all households?
Show answer and reasoning
No.
Household resources, needs and access differ; the average omits their distribution.
Should composite-score weights and exclusions be available to readers?
Show answer and reasoning
Yes.
They affect the result and can hide important adverse outcomes.
Key ideas
- Use the same useful function and an explicit boundary for comparison.
- Read absolute resource totals beside ratios.
- Keep access, livelihoods, safety evidence and environmental outcomes distinguishable.
- Disclose summary rules, data quality and unresolved information.
