Sustainability at a mega-event spans ecological, social, and economic questions that cannot be captured by one physical unit. This calculator treats them as a structured scoring exercise: nine user-supplied criterion scores are grouped into three dimensions and then normalized into a single 0–100 summary.

What this calculator does

The Olympic Games Sustainability Calculator averages three ecological criteria, three social criteria, and three economic criteria. It reports the three dimension scores and their equally weighted overall average. The ecological fields are new construction, visitor footprint, and event size; social covers public approval, social safety, and rule of law; economic covers budget balance, financial exposure, and long-term viability.

How to use it

Score every criterion from 0 to 100 using a consistent evidence standard. Decide before entering numbers what a high score means—for example, whether a higher visitor-footprint score represents better or worse performance—and apply that interpretation consistently. The calculator does not supply the evidence or reverse-score unfavorable criteria for you.

How the calculation works

Each dimension score is the arithmetic mean of its three entered criteria. Ecological score = sum of its three values ÷ 3, with the same method for social and economic dimensions. Overall sustainability = (ecological + social + economic) ÷ 3, so each dimension contributes one-third of the final 0–100 result.

Example

Using the default scores, ecological performance averages about 73.33, social performance 60.00, and economic performance 33.33. The overall score is therefore (73.33 + 60.00 + 33.33) ÷ 3 ≈ 55.56/100, which the calculator labels as a moderate sustainability score.

How to interpret the result

The overall number is only as meaningful as the scoring rubric behind the nine inputs. Use the dimension scores to avoid hiding a weak area behind a strong one; an event could score well ecologically but poorly economically, for example. The tool is strongest as a transparent comparison framework when the same rubric is applied to multiple events.

Limitations and notes

This is a conceptual index, not an independently validated Olympic sustainability rating. The calculator gives equal weight to all three dimensions and all criteria within them, and it does not verify evidence, uncertainty, or causal impact. Results can change substantially with subjective scoring choices, so document the source and rationale for every entered criterion.
