Total Score Calculation

The total Proof Sustainability Score on the Scorecard is calculated using a combination of weighted factors and quintile-based scoring. Here’s how it works:

  1. Weighting by Impact:

    • Each factor on the Scorecard is weighted based on its impact level:

      • Low Impact factors: Max of 10 points

      • Medium Impact factors: Max of 20 points

      • High Impact factors: Max of 30 points

  2. Converting Factors to a 0-100 Scale:

    • For factors not on a 0-100 scale (e.g., Reporting History), performance is converted to a proportional score on a 0-100 scale. Each factor is then assigned a score corresponding to the highest value in its quintile.

      • Example: If a factor falls into the ‘Good’ rating (60-79 range), the top score (79) is used for calculation.

  3. Rounding:

    • Decimal points are rounded up to the nearest whole number.

Example Breakdown:

  1. Response Rate:

    • Max 10 points x 0.7 (70%) = 7 points

  2. Reporting History:

    • Max 20 points x 0.79 (from the 'Good' quintile upper bound) = 16 points

  3. Metric Count:

    • Max 10 points x 1.0 (100%) = 10 points

  4. Metric Diversity:

    • Max 10 points x 1.0 (100%) = 10 points

  5. Benchmark Performance:

    • Max 20 points x 0.19 (19%) = 4 points

  6. Improvement Over Time:

    • Max 30 points x 0.29 (29%) = 9 points

Gauge Chart Classifications

Your total score will be categorized as:

  • Poor: 0-19 total points

  • Fair: 20-39 total points

  • Satisfactory: 40-59 total points

  • Good: 60-79 total points

  • Excellent: 80-100 total points

This ensures that your score reflects a balanced view of your sustainability performance across various impactful metrics.
