CarbonTiers tool catalogue · 10 live tools
Ten focused tools: five IPCC sector tools, a complete national inventory, corporate and city footprints, and the MRV and EU ETS workbooks for regulated installations. Compare their purpose, standards and coverage before you begin — each has its own user guide.
The quickest way to choose
What is your reporting boundary?
A single source category, a whole country, a company, a city and an EU ETS installation each need a different inventory structure. Pick the card that matches your work.
Source-category calculation
Choose an IPCC sector tool
For a defined energy, industrial, agriculture, land-use or waste calculation, its multi-year inventory and its mitigation scenarios.
National or multi-sector inventory
Choose the National Reporting Suite
For all five IPCC sectors in a shared workspace, with key category analysis, cross-sector QA/QC and the CRT / BTR reporter.
Organisation boundary
Choose CarbonTrack
For a company’s Scope 1, 2 and 3 footprint under the GHG Protocol.
Community or city boundary
Choose CityCarbon
For a municipality’s GPC inventory, SECAP reporting, target tracking and mitigation scenario planning.
ETS monitoring and verification
Choose MRV Pro
For an installation’s monitoring plan, tier management and verification-readiness dossier.
ETS allowances and carbon cost
Choose CarbonTrack ETS
For free allocation, the compliance position against verified emissions and carbon-cost scenarios.
01 · Source-category tools
Use a sector tool when the work starts with a defined source category or facility dataset. Each tool combines Tier 1/2/3 calculation with a multi-year inventory series; all five add scenario modelling across 82 mitigation options, with LULUCF tracking land conversions across source and destination categories.
Build a transparent energy inventory, carry it into a multi-year series and model forward-looking BAU and mitigation pathways.
Built for Energy operators · Industrial sites · Inventory teams
Separate process emissions from energy combustion and model technology or process-transition pathways.
Built for Manufacturers · Exporters · Verification teams
Quantify agricultural emissions and model livestock, fertiliser, rice and land-management mitigation pathways.
Built for Agriculture ministries · Producers · Carbon projects
Account for land-sector emissions, carbon-stock changes and removals in one signed inventory, with land conversions tracked in both the source and destination categories.
Built for Forestry agencies · Land managers · Project developers
Estimate waste-system emissions and model disposal, recovery, treatment and methane-capture pathways.
Built for Waste operators · Water utilities · Inventory teams
02 · Consolidated reporting
Use the National Reporting Suite when the deliverable is the whole inventory rather than an isolated calculation. Sector results share one reporting year, GWP selection and file manager, then run through key category analysis, cross-sector consistency checks and the UNFCCC CRT summary tables and BTR reporter.
Run all five IPCC sectors in one workspace with a shared year, GWP set and file manager — then take the inventory through key category analysis, cross-sector QA/QC and the UNFCCC CRT / BTR reporter.
Built for National inventory teams · Consultancies · Research programmes
03 · Purpose-built boundaries
An organisation and a community have different consolidation rules, scopes and reporting templates. CarbonTrack and CityCarbon therefore operate as dedicated tools with independent licences.
An affordable corporate footprint tool for companies that want to calculate their own Scope 1, 2 and 3 emissions in-house, find their largest sources and turn them into a reduction plan with targets — without paying for a consultancy or a licensed LCA database.
Built for Companies calculating their footprint in-house · SMEs and mid-sized companies · Sustainability, energy and operations teams
Build a decision-ready community-scale inventory for a city, municipality or metropolitan authority, then carry it through to targets, an action register, a mitigation scenario and a submission-ready Covenant of Mayors workbook.
Built for Municipalities · Metropolitan authorities · Covenant of Mayors signatories
Run the full monitoring, reporting and verification cycle of an ETS installation in one workbook: monitoring plan, tier management, uncertainty, control system, annual emissions report, verification file, improvement report and a 10-year evidence register. It does not replace statutory MRV or accredited verification.
Built for ETS installations · MRV specialists · Emissions-trading consultants
Answer the three questions an ETS installation actually has to budget for: how many allowances are we entitled to, how large is the gap against verified emissions, and what does that gap cost. Built on the EU ETS rulebook: Annex I scope, FAR benchmarks and the CBAM free-allocation phase-out.
Built for ETS installations above the threshold · Compliance and carbon finance teams · Emissions-trading consultants
Shared platform foundation
Every CarbonTiers workspace is designed around transparent methods, traceable data and outputs that remain useful outside the platform.
Calculation method, factor source, GWP version and reporting boundary stay explicit.
Move from defaults to country, technology or facility-specific data without changing tools.
Export tables, charts and reports built for review, handover and continued analysis.
Each tool shows only the modules relevant to its accounting boundary and purpose.
New — Organisations
Whichever tool you license, it comes with seats for colleagues. Invite them by email and they open the same tools under your licence — no second subscription.
On top of you: Pro plans add one seat, the corporate tools two, and the bundles three. Add more at any time for the same term as your licence.
Invite as many people as you like to view a workbook — a client or an auditor never costs you a seat. Seats only govern who can open the tools.
If two people edit the same workbook, the platform warns you before anything is overwritten.
