Scoring Methodology
Transparent, evidence-based sustainability scoring for individuals and professionals.
S.O.E uses a weighted scoring system across five pillars to calculate an overall sustainability score from 0-100. The methodology is designed to be transparent, verifiable, and applicable to both individuals and professionals.
Your score reflects both your declared actions and the quality of evidence supporting those claims. This dual-score approach ensures that verified claims carry more weight than self-reported data.
S.O.E uses an expanded 8-pillar scoring system. Legacy assessments use 5 pillars, while new assessments include Water, Finance, and Consumption for more comprehensive evaluation.
🌍 Footprint & Energy
25% Weight (Expanded) / 40% (Legacy)Measures your direct environmental impact through energy use, transportation, and diet.
💧 Water Conservation
10% Weight (New)Evaluates water usage habits and conservation measures in daily life.
🛍️ Responsible Consumption
15% Weight (New)Assesses buying habits, product lifecycles, and conscious consumption patterns.
💰 Sustainable Finance

S.O.E distinguishes between Declared Score and Trusted Score:
Declared Score
Your raw score based on self-reported answers. This represents what you claim about your sustainability practices.
Trusted Score
Your verified score = Declared Score × Data Quality Factor. This is the score shown on leaderboards.
Data Quality Factor
The Data Quality Factor ranges from 0.4 to 1.0 based on verification evidence:
| Evidence Level | Factor | Description |
|---|---|---|
| Self-reported | 0.40 | No supporting documents |
| Partially verified | 0.60-0.80 | 1-2 approved documents |
| Fully verified | 1.00 | 3+ approved documents |
Bronze
40-59 points
Silver
60-79 points
Gold
80-89 points
Platinum
90+ points
S.O.E automatically checks for inconsistencies in your data to maintain integrity:
- Cross-pillar consistency: Flags if claims in one area contradict another (e.g., zero flights but frequent international speaking)
- Outlier detection: Identifies unusually low or high values that may need verification
- Missing evidence: Suggests areas where documentation would strengthen your profile
- Suspicious changes: Monitors for sudden large changes in reported data
Flagged items don't automatically reduce your score but may affect your trusted score until resolved.
Beyond your sustainability score, S.O.E includes gamification features to encourage consistent engagement and community competition.
