Net Positive Impact Score: impact, measured seriously
In the world of sustainability, much is promised and little is measured. The Net Positive Impact Score (NPIS) is Simbial's answer: a transparent and potentially certifiable methodology that assigns every project a score based on real physical outcomes, not declarations.
The formula: Handprint minus Footprint
Every project generates positive impacts (handprint: energy saved, CO₂ avoided, materials recovered, people trained) and negative impacts (footprint: resources consumed to carry it out). The Net Positive Impact Score is the difference: NPIS = Handprint − Footprint. One single number — honest and comparable.
Three dimensions: environment, society, economy
Indicators cover the three dimensions of sustainability: environmental (emissions, energy, water, waste, biodiversity), social (training, inclusion, health, community), and economic (efficiency, local supply chains, quality employment). Each indicator is expressed in its native physical unit.
Physical indicators, public coefficients
The certifiable truth lies in physical units: kWh, kg of CO₂ equivalent, tonnes of material, hours of training. Conversion into points is carried out using public, versioned coefficients inspired by international reference methodologies: anyone can verify how a score is generated.
Four levels of certification
Each indicator declares its own confidence level: estimated, assessed by AI for plausibility, validated by the lead with evidence, certified with documentation. The higher the level, the more the data carries weight — and the more it can be used in corporate reporting.
And for people: the Talent Score
Each talent accumulates the impact of the projects they have contributed to along with their individual merit (quality of deliverables, consistency, collaboration). The two values always remain separable: anyone viewing a profile can see how much comes from collective results and how much from the individual's personal journey.

Is the Net Positive Impact Score certifiable?
The methodology is built to be: physical indicators with method and evidence, public coefficients, explicit verification levels. The highest level requires documentation that can be checked by third parties; for regulatory use, validation by the company's auditors is required.
Who calculates the scores?
Calculations are performed exclusively on Simbial's servers based on the indicators register: no score can be modified by participants. The AI assesses the plausibility of declarations; evidence remains tracked.
How is it different from other sustainability scores?
Three choices set it apart: it starts from native physical units rather than self-assessments; it explicitly subtracts negative impacts (footprint); it makes conversion coefficients public. Net Positive Impact Score is a proprietary methodology of Simbial (Magnisi srl).
