How does CO2 Lab collect data from suppliers?

Suppliers can submit data directly through invoices and reports sent via email. Our AI extracts emissions-relevant data automatically. No portal training or onboarding needed for your suppliers.

What if our suppliers don't have emissions data?

CO2 Lab supports both activity-based and spend-based calculation methods. Even with minimal supplier data, we can estimate Scope 3 emissions using industry-average emission factors and refine as better data becomes available.

Can we track progress across our supply chain?

Yes. CO2 Lab gives you a consolidated view of supplier emissions, highlights hotspots, and tracks data quality improvements over time.

Is the check-up free, and am I committing to anything?

Yes. It's a free 30-minute chat with no obligation. We talk through where you're at with your reporting, point you in the right direction, and can show you the product if it's useful.

For Procurement Teams

Take control of your Scope 3 emissions

Scope 3 is the biggest and messiest part of most footprints. Forward what suppliers already send you; the analyst categorises it across all 15 categories and ranks it by impact.

You stay the reviewer

Every supplier line, traceable

Each Scope 3 figure shows the method behind it: activity-based where a supplier gave you real data, spend-based where all you have is an invoice total, plus the factor and its source. When a number looks off, you can see whether it's the data or the method, not just accept it.
