Calculators

The Calculation Hub is the core engine that processes raw data into standardized sustainability scores. It supports real-time calculations for individual products, orders, and entire shopping carts.

How it works

You provide product data with material composition, weight, and transport parameters
The engine applies LCA (Life Cycle Assessment) methodology
Results are returned as standardized impact scores

Calculation types

Type	Description	Use case
CO2 Equivalent	Total greenhouse gas emissions in kg CO2e	Product pages, cart totals
MKI Score	Milieukostenindicator (environmental cost) in EUR	Construction, infra projects
Water Footprint	Water consumption in liters	Food, agriculture
Energy Use	Total energy in kWh	Manufacturing, electronics
Custom Metric	User-defined calculations	Sector-specific needs

Basic calculation

mutation {
  calculateImpact(input: {
    productId: "prod_abc123"
    quantity: 50
  }) {
    co2Equivalent
    mkiScore
    waterFootprint
    energyUse
    breakdown {
      phase
      contribution
      percentage
    }
  }
}

The breakdown field provides a phase-by-phase analysis showing where in the lifecycle the impact occurs:

{
  "data": {
    "calculateImpact": {
      "co2Equivalent": 620.0,
      "mkiScore": 43.5,
      "waterFootprint": 15000,
      "energyUse": 890,
      "breakdown": [
        { "phase": "RAW_MATERIALS", "contribution": 310.0, "percentage": 50 },
        { "phase": "MANUFACTURING", "contribution": 155.0, "percentage": 25 },
        { "phase": "TRANSPORT", "contribution": 93.0, "percentage": 15 },
        { "phase": "USE_PHASE", "contribution": 31.0, "percentage": 5 },
        { "phase": "END_OF_LIFE", "contribution": 31.0, "percentage": 5 }
      ]
    }
  }
}

Calculation with transport

Include transport parameters for accurate Scope 3 calculations:

mutation {
  calculateImpact(input: {
    productId: "prod_abc123"
    quantity: 100
    transportMethod: TRUCK
    distance: 500
    distanceUnit: KM
    originCountry: "NL"
    destinationCountry: "DE"
  }) {
    co2Equivalent
    transportContribution
    equivalency {
      description
      value
    }
  }
}

Shopping cart calculation

Calculate the total impact of a shopping cart in real-time:

mutation {
  calculateCartImpact(input: {
    items: [
      { productId: "prod_abc123", quantity: 2 },
      { productId: "prod_def456", quantity: 1 },
      { productId: "prod_ghi789", quantity: 5 }
    ]
    shippingMethod: STANDARD
    shippingAddress: { country: "NL", postalCode: "1012AB" }
  }) {
    totalCo2Equivalent
    totalMkiScore
    perItem {
      productId
      co2Equivalent
    }
    shippingImpact
    equivalency {
      description
      value
    }
  }
}

Supported lifecycle phases
