    Spend tells you what you spent.

    Simple tells you what you emitted, line by line, from the quantities and materials on your own documents.

    Two offers. Same price.

    Offer A · €10,000
    Offer B · €10,000

    Same spend, same estimate. The footprint follows the price.

    01

    Spend-based

    Spend-based estimates are easy to report, but they tell you what you spent, not what you emitted. A cheaper supplier looks cleaner, whatever it actually delivers.

    02

    Activity-based

    Each line is matched to the most specific factor available: manufacturer PCF or EPD first, then the best-matching database factor. You always see which factor was used and why.

    03

    Carbon is a cost

    CO₂e is a cost like money: if you defer it, it doesn't disappear. It compounds and often hits dramatically later.

    Built on recognised standards.

    Built on globally recognised standards, ensuring every calculation is defensible, transparent, and ready for audit. Every figure follows the GHG Protocol and is matched to the most specific data available, from manufacturer EPDs to recognised LCA databases.
