Bring your emissions data, reporting and reduction targets into one carbon accounting and management platform. Sustrax MX helps teams manage Scope 1, 2 and 3 emissions across sites and reporting periods, with support from Carbon Footprint Ltd.
Carbon accounting software from Carbon Footprint Ltd: a calculation engine with annually updated emission factors, backed by more than 20 years of carbon expertise. Choose a step to see what your team can do with Sustrax MX.
Capture fuel, electricity, travel, freight, waste, water and purchasing data for every site. Enter records directly, upload category templates in bulk, or let AI Fill (Beta) read bills and invoices into a review table for your team to confirm.
Every record is converted with annually updated emission factors: UK Government conversion factors from Defra, plus country-specific electricity factors from CaDI, Carbon Footprint Ltd’s proprietary emissions database. Each entry lands in its GHG Protocol scope and category automatically, across activity-based and spend-based methods and advanced categories such as IT equipment, bulk materials, ingredients and paper.
Explore Scope 3 reporting →Give site teams, finance and sustainability leads the access they need. Collect data where the activity happens, compare locations by month and year, and consolidate company results at any scale.
Explore multi-site management →Attach evidence, add notes and apply data tags and custom fields to each record, and group locations with site tags, so every figure can be traced back to its source when reviewers, auditors or verifiers ask.
Organise emissions by GHG Protocol scope and category, compare location-based and market-based electricity, and apply the SECR, PPN 006, SBTi and Net Zero Standard reporting filters before you export the data behind your CSRD, CDP and other disclosures.
See how reporting works →Set a baseline year, model active, passive and custom reduction pathways against business as usual, and see actual emissions plotted alongside them through to 2050, with Near-term, Long-term and Net Zero milestones from the Carbon Footprint Net Zero Standard marked on the timeline, and room for extra rows such as an SBTi-aligned pathway. AI recommendations suggest where to act next.

For a sustainability manager, the challenge is often collecting consistent information from colleagues, offices and suppliers. Sustrax provides a shared place for that work: enter or upload activity data, check calculations, retain evidence and explore the resulting footprint.
Finance teams can bring in purchasing data, site teams can contribute energy records, and reviewers can examine results. Role-based access helps each person work with the information relevant to their responsibilities.
Emission factors are maintained for you: UK Government conversion factors from Defra, with country-specific electricity factors from CaDI, Carbon Footprint Ltd’s proprietary emissions database. Your team works with activity data, not factor lookups.
Sustrax organises emissions by GHG Protocol scope and category. Its analysis controls include location-based and market-based electricity reporting, site and date filters, and reporting views for SECR, PPN 006, SBTi and the Net Zero Standard.
For example, the SECR filter selects relevant categories and adds UK/global energy breakdowns; filtered data can then be exported. These tools support the calculation and data-preparation work. They do not replace checking your organisation’s reporting obligations, boundary, disclosures or verification needs.
Discuss the categories and reporting outputs you need when choosing a package. Carbon Footprint Ltd’s verification and assurance services offer a separate route to expert review.
Compare an active reduction target with a business-as-usual pathway, review actual emissions against the baseline, and record assumptions beside your targets. Monthly tracking in MX helps you spot changes during the year. Intensity metrics can put emissions in context alongside measures such as employee numbers or turnover.
MX suits organisations that need monthly tracking, multiple contributors and a broader range of inputs. AX offers annual tracking with expert review. For a smaller first footprint, explore the Lite range before comparing all plans and limits.
Sustrax is part of Carbon Footprint Ltd’s wider offering, alongside carbon footprinting expertise, reduction planning and the carbon credit marketplace. Use your footprint to prioritise reductions, then explore public project information when considering support for climate projects.
