Every framework.
Fully covered.

CarbonTrack is built from the ground up to satisfy every major UK and international carbon reporting requirement. Not adapted. Built for it.

Compliance Frameworks

Built for the frameworks that matter.

UK mandatory reporting, government tender compliance, and international standards. All covered in one platform.

Core Methodology

DEFRA 2025/26

UK Government greenhouse gas conversion factors. The authoritative source for UK carbon accounting. CarbonTrack pre-loads every relevant factor and applies them automatically.
  • All 2025/26 factors pre-loaded in the database
  • Applied automatically. No manual lookup.
  • 6 decimal place precision on every calculation
  • Updated annually when DEFRA publishes new values
  • DEFRA table and row referenced on every trip record
Mandatory UK Reporting

SECR

Streamlined Energy and Carbon Reporting. Mandatory for UK quoted companies, large unquoted companies and LLPs meeting the size threshold. Scope 3 travel data must be included in the Directors' Report.
  • Category 6 business travel data structured for SECR
  • Category 7 commuting data included
  • Report export formatted for Directors' Report inclusion
  • Year-on-year comparison built in
  • Intensity metric calculations supported
Government Tenders

PPN 06/21

Procurement Policy Note 06/21. Mandatory Carbon Reduction Plans required for UK government contracts above £5 million. Scope 3 Category 6 travel data is a required component. Get compliant or lose the tender.
  • Category 6 data structured for Carbon Reduction Plans
  • CRP template pre-populated with your data
  • Audit trail satisfies government assessor requirements
  • Baseline year and reduction trajectory supported
  • Multi-site aggregation for complex organisations
International Standard

GHG Protocol Scope 3

The international standard for corporate Scope 3 emissions accounting. CarbonTrack covers Category 6 (Business Travel) and Category 7 (Employee Commuting), the two travel categories in the GHG Protocol standard.
  • Category 6 business travel. Fully aligned.
  • Category 7 employee commuting. Fully aligned.
  • GHG Protocol distance methodology followed
  • Boundary and attribution methodology documented
  • Suitable for third-party assurance
Climate Disclosure

TCFD

Task Force on Climate-related Financial Disclosures. Mandatory for UK-listed companies and large asset managers. Scope 3 travel emissions are a key input to climate-related risk and opportunity reporting.
  • Travel emissions data ready for TCFD disclosures
  • Year-on-year trend data for trajectory reporting
  • Methodology notes suitable for TCFD documentation
  • Integration with broader Scope 1, 2 data possible
ESG Reporting

ESOS & CSRD

Energy Savings Opportunity Scheme (UK) and Corporate Sustainability Reporting Directive (EU). Both require Scope 3 travel data for qualifying organisations. CarbonTrack exports data in formats suitable for both.
  • ESOS Phase 3. Category 6 and 7 data structured.
  • CSRD-formatted export on Pro tier roadmap
  • GRI-aligned reporting structure
  • Raw data export for any ESG platform ingestion
DEFRA Factors Included

Every factor. Pre-loaded.

No manual lookups. No outdated spreadsheet factors. Every relevant DEFRA 2025/26 emission factor is in the database and applied automatically.

By Industry

Compliance by sector.

Different industries face different mandatory frameworks. Here's what applies to you.

Construction & Civil Engineering

PPN 06/21SECRGHG Protocol

Government contracts require Carbon Reduction Plans. SECR applies if you meet size thresholds. Both require Category 6 travel data.

Manufacturing & Industrials

SECRESOSGHG Protocol

SECR mandatory. ESOS Phase 3 requires energy and emissions data. Both covered by CarbonTrack output.

Financial Services

TCFDSECRCSRD

TCFD mandatory for listed firms. SECR applies. CSRD expanding to UK operations. High travel volume makes Category 6 material.

Professional Services

SECRGHG ProtocolClient ESG

Client ESG pressure growing. SECR applies at threshold. Partners travelling constantly. Every trip needs to be defensible.

Public Sector

PPN 06/21Gov Net Zero

Government Net Zero commitments require Scope 3 reporting. PPN 06/21 applies to procurement. Travel data needed across departments.

Healthcare

NHS Net ZeroGHG Protocol

NHS Net Zero Strategy requires Scope 3 travel reporting. Community staff, home visits and conference travel all Category 6 and 7.

The compliance statement your auditor needs to see

"Data methodology: Fully mapped to DEFRA 2025/26 Conversion Factors. Scope 3 Category 6 and 7 calculated using GHG Protocol methodology. Distance calculations use Haversine Great Circle formula for aviation (DEFRA-specified) and Google Maps Distance Matrix for road and rail. Full calculation trail available per trip on request."
