Environmental Risk Score with environmental consequence score of 20 score: a worked example

This scenario runs the environmental risk score calculation on the strong side: environmental consequence score of 20 score, with every other input held at its documented default. an EHS lead needs to prioritize environmental risks and corrective actions

The inputs for this scenario

  • Environmental consequence score: 20 score (raised for this scenario; the documented default is 8)
  • Occurrence likelihood score: 5 score (unchanged)
  • Control weakness score: 6 score (unchanged)

Working through the calculation

  • Applying the documented formula (Environmental risk score = weighted consequence, likelihood, and control weakness score) to the inputs above produces each figure below.
  • At this operating point the engine returns 11.25 score for environmental risk score, the number this scenario is built around.
  • At this operating point the engine returns 20 score for environmental consequence score.
  • At this operating point the engine returns 5 score for occurrence likelihood score.
  • At this operating point the engine returns 6 score for control weakness score.

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 74.42% above the baseline at 11.25 score.
  • Use it when building or reviewing an environmental aspects-and-impacts register and ranking which risks to mitigate first. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance
