Environmental Risk Score with environmental consequence score of 4 score: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop environmental consequence score to 4 score, then walk the calculation through step by step. Score environmental risk from consequence, likelihood, and current-control strength.

The inputs for this scenario

  • Environmental consequence score: 4 score (the input this scenario stresses; the baseline uses 8)
  • Occurrence likelihood score: 5 score (held at the documented default)
  • Control weakness score: 6 score (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Environmental risk score = weighted consequence, likelihood, and control weakness score.
  • Environmental risk score works out to 4.85 score at these inputs, and this is the headline figure for the scenario.
  • Environmental consequence score works out to 4 score at these inputs.
  • Occurrence likelihood score works out to 5 score at these inputs.
  • Control weakness score works out to 6 score at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where environmental consequence score sits at 8 score and the headline result is 6.45 score, this scenario comes in 24.81% below the baseline at 4.85 score.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to environmental consequence score, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. The score is only as good as the scoring rubric behind it; inconsistent scales between assessors make scores look comparable when they aren't.
