CarbonTrack Core
GHG Protocol · ISO 14064-1
Corporate Scope 1, Scope 2 and all 15 Scope 3 categories, inventory controls, CBAM readiness and professional reports.
Scope 1 activity data can feed MRV Pro source streams.
Standalone licence
No credit card, no demo call. Pick your sector, enter your data, see your Tier 1 result instantly — powered by 140+ country grid factors and IPCC 2006 methodology.
Built for consultancies, corporate ESG teams and national inventory compilers worldwide.
Source-category calculations, a complete national inventory, corporate and city footprints, and regulated installation workflows require different structures. CarbonTiers gives each one a focused workspace, while CarbonTrack Core, MRV Pro and ETS pass the relevant data forward without collapsing their separate licences or responsibilities.
Compare all products, standards and coverageSource category
Energy, IPPU, Agriculture, LULUCF and Waste — focused calculations with sector-specific methods and tiers.
Multi-sector boundary
Bring all five IPCC sectors into one reporting year, GWP basis and consolidated inventory workspace.
Organisation boundary
Account for Scope 1, Scope 2 and all 15 Scope 3 categories, with CBAM/ETS readiness analysis and verification-supporting reports.
Community boundary
Prepare GPC BASIC/BASIC+ inventories and SECAP reporting for cities and local authorities.
CarbonTrack product family
Three standalone professional workbooks form one controlled operating chain. Core builds the corporate inventory, MRV Pro documents the monitoring and verification cycle, and ETS turns verified emissions into an allowance position and carbon-cost view. Buy only the stage you need or activate a bundle.

CORE + MRV PRO + ETS
For regulated operators and advisers that need all three workbooks and their controlled data hand-offs.
Data & methodology
Every factor in the calculation engine is traceable to a published, internationally accepted source. Each result discloses the exact method, tier and factor reference it used — and every workspace keeps that lineage visible without forcing unrelated accounting boundaries into one interface.

International Energy Agency
Grid electricity carbon intensity for 140+ countries and energy-use benchmarks.
Additional grid and residual-mix data: Ember, AIB, RTE, national TSOs (incl. TEİAŞ); spend-based Scope 3: EXIOBASE / EEIO. Compliance frameworks supported: EU CBAM, CSRD / ESRS E1 and CDP disclosure.
Enter a single day and get your footprint in kg CO₂e across transport, home and office energy, digital use, food, purchases, water, services and waste — with an uncertainty range and benchmark comparisons. Built on the same transparent factor library as our corporate inventory tools.
Results are estimates based on activity data and average emission factors; every factor and assumption used is listed in the report.
Calculate flights with radiative forcing index (RFI), hotel accommodation nights, rail alternatives, and company car journeys under IPCC standards.
Measure location-based purchased electricity, HVAC heating/cooling, digital workloads, and employee workstation energy footprints.
Understand consumption-based vs. generation-based grid intensities, residual mixes, and I-REC / YEK-G contractual market instruments.
Every paid plan includes seats for colleagues. Invite them by email — they open the same tools under your licence, with no second subscription to buy.
Included with your plan, on top of you: Pro adds 1 seat, corporate tools 2, bundles 3.
Add as many people as you like to view files — a client or auditor never costs you a seat. Seats are only for opening the tools.
If two people edit the same file, the platform warns you before anything is overwritten.
Need more than the included seats? Add them for the same term as your licence, from your organisation settings.
