How the work runs, step by step

Q: How the work runs, step by step

For Scope 3 categories 1, 2 and 15, yes. DitchCarbon is a specialist Scope 3 carbon accounting tool rather than a full inventory platform, so it holds the verified supplier and portfolio data behind those categories and feeds your inventory or reporting system. That replaces fragmented spreadsheets and annual snapshots with continuous refresh and documented sources.

This is the operating model behind the data: how a supplier list or portfolio becomes a defensible Scope 3 total and then a reduction plan. Four steps, in order.

It replaces the survey cycle. Instead of asking every organisation for everything and waiting, we start from what is already published, then ask a smaller number of organisations for the figures that actually move your total.

Step 1: bring the supplier and portfolio data together

We start with the spend and supplier data you already hold, match it to the right legal entities, and attach whatever each organisation has published. That maps the value chain, shows where supplier-specific calculation is possible, and surfaces the hotspots. Numbers you can defend within 2 weeks, before anyone has been contacted.

Step 2: engage the organisations that matter

Primary data makes a Scope 3 total more defensible, and asking for it should not be a burden on either side. We contact the organisations where a primary figure would change your number, with a short localised request, and validate what comes back before it enters your dashboard. Everyone else stays covered by public data and labelled estimates.

Where an organisation cannot provide product level data, there is a documented fallback: supplier-specific activity data first, then supplier-specific spend, then published industry averages. Every figure shows which step produced it, so coverage gaps are visible rather than hidden.

Step 3: turn the data into evidence

Every figure is validated, versioned and linked to its source, so the trail from a reported total back to a document stays intact. That is what makes the output auditable, and it is what a third-party auditor asks for first. Dashboards show the hotspots, progress against targets, and the detail behind any supplier or category.

Step 4: put the data in the buying decision

Emissions data changes outcomes when a category manager sees it before award, not in a report afterwards. Scorecards and peer benchmarks sit in the procurement tools your team already uses, so bidders can be compared on emissions intensity and disclosure quality alongside cost and quality.
