The problem

Why accurate CO₂ data matters

Many companies struggle to quantify their environmental impact, making it difficult to reduce emissions and stay ahead of regulations.
Increasing regulations require precise emissions data
Inaccurate calculations lead to missed reduction opportunities — AI-assisted analysis helps close the gap
Transparency is key for compliance and competitive advantage

Why it matters

Leave behind the uncertainty of spend-based methods

Traditional spend-based climate data offer limited visibility, while a activity-based approach uses real operational data to provide a clearer and more accurate direction.

Spend-based

The spend-based method can be a practical entry point for estimating CO₂ emissions when detailed data is lacking. However, it is sensitive to inflation and price changes, which can distort the link between cost and actual emissions.

Activity-based

Using real operational data, this method ensures precise carbon calculations, enabling informed decisions and true accountability.
