Finishing verification

Today, trying to scale EPDs means cutting corners.

Calculators that never touch your BOM.
Fill out a simplified template and get a static PDF. It's manual, slow, error-prone, and disconnected from your products.
Single EPDs that stretch across entire product families.
Simple scaling gets most products wrong. Getting it less wrong takes more work than calculating each product directly.
Rubber-stamp verification that puts your claims at risk.
Internal verification won't hold up for long. More and more procurement teams demand third-party verified EPDs.

Variable is built for scale. Product-specific. Third-party verified. Always up to date.

90%
Time saved for your team.
100×
Lower cost per EPD than consultants.
<60 days
From kickoff to live system.

Let machines do the manual work. Automation handles the tedious 90%.

From raw data to live models. AI transforms your input data, rule-based automations build models in minutes.
