Decide sustainability trade-offs and record why
A resource-saving idea clashes with cost or accessibility, and the committee must decide and record why.
The short answer
When a sustainability choice has a downside, compare the options on the same criteria, name who decides, and record the choice and the reason. A choice that costs attendees access or adds cost without a stated reason will not hold up when someone asks later.
List what each option gives up, not only what it saves. Record what you can evidence in the benefit evidence tracker. Call the preferred option better for the environment only if a competent party has shown it with a stated method.
Typical clashes
- Digital materials reduce printing but may exclude attendees without devices. See digital material access alternatives.
- Reusable cups and plates reduce disposables but need washing, handling space and caterer agreement.
- Date-free signage can be reused but may look plain or need changeable panels. See the reusable signage plan.
- Fewer deliveries lower packaging but may need storage space at the venue.
Compare the options on the same criteria
| Criterion | Option A: keep as is | Option B: resource-saving change | Who answers |
|---|---|---|---|
| Cost this event | Quote or estimate | Quote or estimate, including extra labour | Finance |
| Access and inclusion | Who can use it? | Who may not, and what alternative? | Accessibility adviser |
| Attendee experience | Familiar | What changes for attendees? | Programme chair |
| Supplier capability | Already agreed | Can supplier deliver it, in writing? | Operations lead |
| Evidence available | What record would exist? | What record would exist? | Secretariat |
| Risk and fallback | Known | What if it fails on the day? | Project lead |
How to decide
Fill in both columns with facts or quotations, and mark unknowns as questions with an owner, not guesses.
The decision owner chooses and records the reason in one or two sentences, including what the choice gives up. If accessibility or safety is affected, the matter goes to the competent party, not the committee.
Steps to follow
- State the choice in one line and the two options.
- Fill the table and list the unknowns, each with an owner and date.
- Ask the competent party any access, food safety or safety question that arises.
- Decide at a set meeting and record the reason.
- Add what you can measure to the evidence log, and revisit after the event.
Worked example · Fictional example
Reusable plates or disposable plates at a lunch
Fictional organisation and figures, for illustration only.
A fictional association debates reusable plates for a lunch for about 300 people. The caterer's quote for reusable ware is higher, and washing needs a space the venue has not confirmed. Disposable plates need no extra space.
The operations lead asks the venue in writing about washing space and the caterer about its process. Until both answer, the committee chooses disposable plates for this event, records the reason and sets reusable ware as a question for next year. Environmental benefit is marked not measured.

Trade-off decision record
Copy one block per decision. Leave unknowns as questions with an owner.
- Choice being decided:
- Option A and Option B, in one line each:
- Cost of each, from quotes or estimates (mark which):
- Access and inclusion effects of each, and competent party consulted:
- Supplier capability confirmed in writing (yes / no / waiting):
- Unknowns, each with owner and date:
- Decision, decision owner and date:
- What the choice gives up:
- What will be recorded as evidence afterwards:
- When it will be revisited:
Handle it in-house, or bring in help?
Your team can usually handle this when
- One or two clear options, a decision owner and quotes that are easy to compare.
- No access or safety implications.
Outside planning help earns its fee when
- Several clashes at once and no agreed way to weigh them.
- Access, food safety or safety questions need competent parties and a clear record.
- Costs and supplier terms have to be gathered from many suppliers before the committee decides.
Want trade-offs set out for your committee?
An Event Blueprint can set out the options, the comparison table, the questions to suppliers and competent parties, and a decision record your committee can use. The decision stays with your committee. Send the choices you are weighing and the quotes you have. We reply with the level of support that fits.
Questions organisers ask
What if the greener option costs more?
Record the cost, what it buys and who can approve it. The decision owner may accept it, but the reason should be written down.
Can we claim the chosen option is better for the environment?
Only if a competent party has shown it with a stated method. Otherwise report what you counted and mark the rest not measured.
Who decides when access is affected?
Ask a competent accessibility adviser for guidance, and record who made the final decision and why.
