Scope 3 Emissions Reporting
Scope 3 Category 7 reporting from real journey data, not surveys.
RideTandem delivers audit-ready Scope 3 Category 7 (Employee Commuting) emissions reporting based on actual journey data. Every trip on our shuttles is logged, emissions-factored using DEFRA/BEIS (UK) or UBA (DE) coefficients and mapped to the GHG Protocol. Outputs are export-ready for CDP, CSRD, SECR and UK SDS.
The disclosure picture
Commuting is the footprint most employers can't yet measure.
Definition
What is Scope 3 Category 7?
Scope 3 covers the indirect greenhouse gas emissions across a company's value chain. Category 7, Employee Commuting, is the emissions from staff travelling between home and work. Under the GHG Protocol it is reported separately - and for many employers it is one of the larger, least-measured parts of the footprint.
UK-listed companies are moving to Scope 3 disclosure under the UK Sustainability Disclosure Standards (aligned to IFRS S2), while EU operators report under CSRD. Most reporters still rely on survey-based estimates - which auditors increasingly flag as a weak point, because they are prone to response bias, sample error and year-on-year comparability problems.
- Survey bias is a known accuracy issue. Self-reported commuting habits drift between respondents and reporting years, so the number is hard to defend. GHG Protocol data-quality tiers
- Auditors are pushing back on estimates. As Scope 3 assurance tightens, estimated Category 7 figures attract more scrutiny than measured ones. Big-four sustainability assurance commentary, 2024 - source to confirm
- Regulation is converging on mandatory Cat 7. CSRD, UK SDS and SECR are all moving commuting emissions from optional to expected. EU CSRD + UK FRC
- Low-tier data costs disclosure points. Frameworks such as CDP reward higher-quality, primary data over estimates. CDP scoring methodology, 2024 - source to confirm
What it unlocks
What should journey-based Scope 3 reporting deliver?
Six things you get from real trip data that a commuter survey can't give you.
-
Defensible in assuranceA trip-level log plus a clear methodology stands up to your auditor.
-
CSRD / SECR / UK SDS-readyStructured exports formatted for each disclosure framework.
-
Like-for-like year on yearNo survey methodology drift, so trends are genuinely comparable.
-
Granular by site, route, monthDrill into exactly where the commuting footprint sits.
-
Included with the serviceNo separate survey programme to commission and run each year.
-
Survey add-on for the restOptional module covers non-shuttle employees, clearly flagged as estimates.
How it works
How RideTandem's Scope 3 reporting works.
Every shuttle journey becomes a defensible data point - from the moment a rider boards to the figure that lands in your disclosure.
-
1
Log every trip
Distance, vehicle specification and fuel type are recorded automatically for each journey - no survey forms, no recall.
-
2
Apply emissions factors
We apply DEFRA/BEIS factors for UK routes and UBA factors for German routes, updated annually and vehicle-specific.
-
3
Map to GHG Protocol Cat 7
Trips are aggregated by site, route, vehicle and month, then mapped to Scope 3 Category 7, Employee Commuting.
-
4
Export to your framework
Structured outputs export to CDP, CSRD, SECR and UK SDS templates, ready for your assurance team.
Comparison

| Year-on-year comparability | High | Variable | ISO 14064 principle |
| Cost of acquisition | Included with the service | Separate programme | RideTandem pricing |
| CDP disclosure score impact | Tier 1-2 data | Tier 3-4 data | CDP scoring methodology |
More than 210 tonnes of CO₂ offset, with more than 32,000 car journeys replaced in just 12 months.
FAQ
Scope 3 emissions reporting, frequently asked questions
The data is prepared to an audit-ready standard, following GHG Protocol and DEFRA/BEIS guidance. External assurance is performed by your own auditor or sustainability consultant - we provide the full methodology and the underlying trip data to support it.
DEFRA/BEIS (the UK Government GHG conversion factors) for UK routes, and UBA factors for German routes. Both are vehicle-type-specific and updated annually.
The service captures actual journeys made on RideTandem buses. For wider commuting coverage we offer an optional survey module for non-shuttle employees, clearly labelled as estimates in the audit trail so the two data types are never confused.
Yes. Exports are structured to match CDP, CSRD, SECR and UK SDS reporting templates, so the figures drop into your submission rather than needing to be reworked.
As far back as we have operated your service. For new clients, the baseline year starts at go-live, unless you have prior survey data you'd like us to incorporate.
