Who it’s for
Who needs Scope 3 modelling
For most organisations Scope 3 is the largest and most complex part of the footprint, and the part everyone now asks about. You need it if:
Your emissions are mostly upstream
In what you buy and what your suppliers do. That’s most organisations.
You’re setting SBTi targets
Which require Scope 3 targets where it’s material.
You supply the NHS or public sector
And face a full Scope 3 inventory.
Customers are sending you questionnaires
CDP, or their own supplier surveys, which you can’t answer without it.
The engagement
What’s included
Screening first, then modelling where it counts, with the supplier engagement that makes next year’s number better than this year’s.
Category screening
We screen all fifteen Scope 3 categories to find what’s material, so effort goes where the emissions are.
Spend-based and activity-based modelling
A fast spend-based baseline first, then activity-based data where accuracy matters most.
Supplier data collection and engagement
We help you approach your top suppliers by spend and emissions and get usable data back.
Hotspot analysis and reduction priorities
A clear view of where your value-chain emissions sit and where to act first.
Audit-ready reporting
Delivered through NetScope, with sources and assumptions logged so it stands up to scrutiny.
Quality control
Where Scope 3 goes wrong
Everything measured to the same depth
So months are spent on categories that barely move the total.
Spend-based factors treated as the final answer
When they’re a starting point to refine.
No supplier engagement
So the data never improves and the number stays soft.
Awkward categories quietly dropped
And the gap shows up under scrutiny.
The footprint doesn’t reconcile with the accounts
So finance won’t stand behind it.
The process
How it runs
Step 01
Screen and prioritise
We map all fifteen categories against your business to see which are material, and agree where to focus.
Step 02
Model the baseline
We build a defensible baseline using GHG Protocol methodology: spend-based to start, activity-based where it counts.
Step 03
Engage suppliers
We help you approach your priority suppliers for primary data, replacing estimates with real numbers over time.
Step 04
Report and reduce
You get an audit-ready report and a prioritised list of reduction opportunities that feeds straight into your strategy.
FAQ
Common questions
You have to screen all fifteen to show you’ve considered them, but you don’t measure them all to the same depth. We focus effort on the categories that are material to you and document why the rest aren’t.
