Can you handle thousands of SKUs and suppliers?

Yes. CO2 Lab maps your purchase ledger line by line, starting spend-based with EEIO factors for full coverage, and shows the factor and reasoning behind each category so the Scope 3 total is reviewable.

What happens when suppliers send us their own data?

CO2 Lab upgrades that line from spend-based to supplier-specific data, keeps the provenance, and shows your data quality improving over time, without re-doing the model.

Do you cover store energy and refrigeration?

Yes. Store and distribution-centre electricity is your Scope 2, and refrigerant leakage is a fugitive Scope 1 source we capture from your refrigerant logs, with the factor shown per line.

Why not just use a consultant?

A consultant hands you a number and a bill. CO2 Lab hands you the number and the working behind every line, so you can review it, defend it, and re-run it next year without starting over.

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 Retail

The carbon is in the goods on the shelf

Thousands of SKUs, thousands of suppliers, and the footprint is in all of them. Turning that ledger into a number you can defend is data work at scale, before any report gets written. The analyst does that work and shows the factor behind every line.

A spend ledger in, a defensible Scope 3 out

On day one the only complete data most retailers have is a giant purchase ledger, thousands of SKUs and suppliers. Mapping every line to the right factor by hand is slow and hard to defend. The analyst does the mapping, shows the factor and reasoning per line, and hands you a footprint you can review and stand behind under AASB S2.

How it works

Drop in purchase and supplier-spend data, store energy bills and refrigerant logs, the analyst calculates each scope with matched factors, and you report per category, per store or consolidated across the business.

Scope 3 · Category 1

Purchased goods for resale

Goods for resale are the bulk of a retail footprint. CO2 Lab starts spend-based for full coverage using EEIO factors, then upgrades line by line to supplier-specific data as it arrives, so the number gets more precise without the model breaking or the audit trail resetting.

Spend-based coverage from your purchase ledger

Upgrade to supplier-specific data line by line

Primary and secondary data clearly labelled

Category, brand and supplier breakdowns

Electricity per store and distribution centre

Fugitive F-gas from refrigeration

Location- and market-based Scope 2

Inbound freight and distribution

Scope 1, 2 & 3 · Operations

Stores & refrigeration

Store energy is your Scope 2, and for grocery, refrigerant leakage is a real Scope 1 source that audits often flag. CO2 Lab extracts consumption from utility bills per site, captures fugitive F-gas, and follows inbound freight through to the store.

Supplier data

From spend to primary data

The majors are already pushing this: Coles has committed to have 75% of its suppliers by spend set science-based targets by 2027, and Woolworths was the first Australian retailer with SBTi-endorsed targets. As your suppliers return primary data, CO2 Lab swaps it in per line and keeps the provenance intact.
