Corporate Carbon Footprint – Self-Calculated Using Purchase Data

Who is this for?

This is for companies that don't currently measure their emissions and want to establish a baseline. You don't need specialist equipment, consultants, or years of experience — you can get started using financial data you already have.

Three paths to calculating your footprint

When you select "No, we don't measure emissions," you'll see three options:

1. Self-calculated (free) Calculate your footprint yourself using your purchase data. This is the fastest way to establish a baseline at no cost.

2. Consultant-calculated We use an industry-recognised methodology with a dedicated expert to produce a more accurate footprint on your behalf. This is a good middle ground between full audit and self-calculation.

3. Third-party audited Work with us (or an external auditor) to calculate your emissions in a fully auditable way. This is the gold standard — the results can withstand external scrutiny. Book an initial call to get started.

How the self-calculated (spend-based) method works

The spend-based method uses your company's purchasing records to estimate emissions. The principle is straightforward: every product and service you buy has an associated carbon intensity based on industry averages. By analysing your spending patterns, we can build a picture of your footprint without needing detailed energy bills or activity-level data.

What to upload: A purchase data file containing any payments made to third parties in exchange for goods or services — essentially your accounts payable ledger.

Step-by-step:

Required fields:

You need at least one of Category or Product Description, but providing both gives a more accurate result. The category and description are what allow the platform to assign an emissions intensity factor based on industry averages.
