Scope 3 Emissions
Screening, measurement and reduction of value chain emissions across all 15 GHG Protocol categories — upstream and downstream. For most organizations this is over 70% of the footprint.
What Is Scope 3?
Scope 3 covers every indirect emission that sits outside a company's own operations and purchased energy — from the goods and services it buys to the way its products are used and disposed of.
For most organizations, Scope 3 represents over 70% of the total carbon footprint. It is also the hardest scope to measure, because almost none of the data sits inside the company's own systems.
Getting it right means working through suppliers, customers and logistics partners — and being explicit about which categories rest on primary data and which still rest on proxies.
- All 15 Categories
- Supplier Engagement
- SBTi Aligned
Fifteen categories. One measurable footprint.
From first screening to value chain reduction.
All 15 GHG Protocol Categories
Eight upstream, seven downstream. Every category is screened for relevance, and the reasoning is documented either way.
Upstream
- 01Purchased Goods & Services
- 02Capital Goods
- 03Fuel & Energy Related Activities
- 04Upstream Transport & Distribution
- 05Waste Generated in Operations
- 06Business Travel
- 07Employee Commuting
- 08Upstream Leased Assets
Downstream
- 09Downstream Transport & Distribution
- 10Processing of Sold Products
- 11Use of Sold Products
- 12End-of-Life Treatment
- 13Downstream Leased Assets
- 14Franchises
- 15Investments
The GreenGoldTech Scope 3 Framework
Five modules that take a value chain from a blank page to a measured, reducible footprint.
Category Screening & Materiality Assessment
Establish which of the 15 categories actually matter before spending effort on data.
- Relevance screening across all 15 categories
- Spend-based first pass to size each category
- Materiality thresholds agreed with the business
- Prioritised measurement plan
Data Collection & Quantification
Quantify each category with the best method its data will support.
- Supplier primary data collection
- Spend-based and average-data methods
- Activity-based modelling where volumes are known
- Methodology documented per category
Supplier Engagement & Data Quality Improvement
Move the value chain from estimates towards measured data, supplier by supplier.
- Supplier surveys and onboarding
- Data quality scoring per supplier and category
- Capability building for smaller suppliers
- Progressive shift from proxy to primary data
Reporting & Multi-Framework Disclosure
One Scope 3 dataset, mapped to every framework that asks for it.
- GHG Protocol Scope 3 Standard
- CSRD disclosure
- CDP value chain reporting
- SBTi and TCFD alignment
Reduction Strategy & Value Chain Decarbonisation
Turn hotspots into levers the business can actually pull.
- Hotspot identification across categories
- Supplier reduction targets
- Procurement policy levers
- Product redesign and circularity
Fifteen categories. One measurable footprint.
From first screening to value chain reduction.
Built for
Sectors where the value chain, not the site, carries the footprint.
- FMCG & Retail
- Financial Services
- Manufacturing
- Technology
- Food & Agriculture
- Heavy Industry
We Don't Deliver Estimates. We Build Value Chain Intelligence.
Anyone can produce a spend-based number. The work is making it accurate enough to set targets against and defend under assurance.
Every category screened
All 15 categories are assessed for relevance — including the inconvenient ones — and the screening logic is documented.
Suppliers engaged, not surveyed once
We build a supplier data programme that improves year on year rather than a one-off questionnaire.
Data quality is scored, not assumed
Every category carries a quality rating, so you know which numbers can carry a target and which cannot yet.
Documented for assurance
Methodology, sources and assumptions are recorded per category, ready for third-party verification.
Hotspots become levers
Measurement is the starting point: the output is a reduction plan tied to procurement, product and logistics decisions.
Get Scope 3 under control.
Let's start with a screening of all 15 categories, size what actually matters in your value chain, and build the measurement plan from there.
