Five IPCC Sectors·One Corporate Footprint

Calculation tools for every IPCC sector.

Independent calculation modules for each of the five IPCC sectors plus a corporate carbon footprint tool.

Energy

Sector 1Free tier available

Calculate, verify and report greenhouse gas emissions from every energy-sector source — stationary combustion, mobile combustion, fugitive emissions, reference approach and CCS — on a single platform built for international standards. Fully aligned with IPCC 2006 Guidelines Volume 2 — Energy.

Modules

ModuleScope
Stationary CombustionEmissions from coal, natural gas, fuel oil, LPG, biomass and other fuels burned in boilers, furnaces, turbines and generators — broken down by IPCC sector and fuel type
Mobile CombustionRoad, rail, maritime, aviation and off-road fuel consumption — detailed by vehicle category and fuel
Fugitive EmissionsMethane from natural-gas transmission/distribution, coal mining (underground, surface, abandoned) and oil & gas production — plus refrigerant and SF₆ leaks
Reference ApproachTop-down energy balance cross-check — validates sectoral calculations against national supply data (production + imports − exports − bunkers ± stock change)
CCSCarbon capture, transport and geological storage corrections — ensures captured CO₂ is properly deducted from the inventory

Emissions Calculated

  • CO₂, CH₄, N₂O — stationary combustion emissions for all fuel types (by sector and technology)
  • CO₂, CH₄, N₂O — road, maritime, aviation, rail and off-road mobile combustion emissions
  • CH₄ — natural-gas network fugitive leaks, coal mine methane and oil & gas operations
  • CO₂ — national energy balance verification using the reference approach
  • CO₂ — corrections for carbon capture and geological storage (CCS)
  • SF₆ — electrical switchgear and HFC / PFC refrigerant leaks
  • Biomass CO₂ — reported as IPCC memo item (excluded from totals per guidelines)

11 Capabilities·Audit-Ready

Everything you need to calculate, model and report.

From IPCC default factors to plant-specific Tier 3 precision — with CBAM, Scope 2 dual reporting and scenario modelling built in.

Foundation

IPCC 2006 Compliant

All calculations are based on the IPCC 2006 Guidelines methodology. Up-to-date emission factors and international data sets are included for every source category. Your reports are ready for independent international audit.

Country-Specific Emission Factors

Country-specific Tier 2 grid emission factors for 8 countries (Turkey, USA, UK, Germany, France, China, Japan, India) plus the EU-27 average. IPCC 2006 Tier 1 defaults for all other sectors; users can supply their own Tier 2/3 values.

Tier 1 / 2 / 3 Levels

Flexible calculation from default factors to facility-specific advanced precision. Each module allows tier selection based on available data; inventory accuracy increases as you progress.

Excel & PDF Output

All calculation details are exported in report-ready Excel and PDF formats. Source-category breakdown tables, year-on-year comparisons and summary sheets are generated automatically.

Multi-Year Analysis

Multi-year trend analysis and scenario comparison are built in for the energy sector. For other sectors and corporate inventories, annual calculations can be run separately and compared.

GWP AR4 / AR5 / AR6

Switch between IPCC AR4 (2007), AR5 (2014) and AR6 (2021) assessment report GWP values with a single click. Full flexibility according to your reporting standard; all gases are converted automatically.

Scenario Modelling & Mitigation Planning

Emission projections with BAU, IPCC 1.5°C, IPCC 2°C and EU ETS Fit-for-55 built-in templates. Develop NDC-aligned mitigation strategies using a 81-measure sectoral catalogue and custom scenarios (S-curve, polynomial, exponential).

CBAM Cost Simulation

Embedded carbon calculation under the EU Carbon Border Adjustment Mechanism, annual free-allowance phase-in rates and net CBAM certificate cost against the EU ETS price. Third-country carbon prices paid can be deducted.

Built-in Emission Factor Database

40+ IPCC 2006 fuel records (NCV, carbon content), 15+ vehicle/fuel combinations, grid emission factors for EU-27, USA (EPA eGRID), UK (DEFRA), Germany (UBA), France (RTE), China (NDRC), Japan (MoE), India (CEA) and more, plus 14 EEIO sector coefficients — all up-to-date and referenced inside the platform.

Dual Reporting — Scope 2

Parallel location-based (country/regional grid factor) and market-based (REC, PPA, residual mix) calculation per GHG Protocol Scope 2 Guidance. Report the difference between both methods in a single output.

Multi-Country Grid Support

Location-based Scope 2 grid emission factors for 8 countries plus the EU-27 average. Market-based residual mix values for EU, Germany, UK and USA on the roadmap. All factors sourced from national TSOs and official registries (TEIAS, IEA, EPA eGRID, DEFRA, UBA, RTE, NDRC, MoE Japan, CEA).
