Carbon Diagnostic Pro
The most comprehensive free carbon calculator for the GCC. Full Scope 1, 2, and 3 GHG inventory with country-specific emission factors, refrigerant losses, district cooling, and value chain emissions. DEFRA 2024 and IEA 2023 factors built in.
Enterprise-Grade Carbon Management
From quick screening to accredited verification, everything you need to measure, reduce, and verify your carbon footprint in the GCC.
Qatar-Specific Emission Factors
Built-in KAHRAMAA grid emission factors, district cooling coefficients, and desalination energy intensities. Localised data for accurate Qatar-based GHG inventories.
Full Scope 1+2+3
Comprehensive coverage: stationary combustion, mobile sources, refrigerant losses, purchased electricity, district cooling, business travel, commuting, waste, and water.
GCC Grid Factors
Country-specific electricity grid emission factors for Qatar, UAE, Saudi Arabia, Bahrain, Oman, and Kuwait. Updated annually from IEA data.
Reduction Pathways
Prioritised decarbonisation actions ranked by abatement potential. Sector-specific recommendations for energy, transport, buildings, and industry.
Paris Alignment
Assess your trajectory against the 1.5 degrees C global target and Qatar's Nationally Determined Contribution. Science-based target setting support.
GSustain Verified
Optional accredited ISO 14064-3 verification by GSustain's GAB-accredited team. Independent third-party assurance for investor confidence.
Carbon Diagnostic Pro
Get a comprehensive estimate of your organisation's carbon footprint across all three scopes. Full GCC emission factors, refrigerant tracking, district cooling, and value chain emissions. Takes under 5 minutes.
Scope 1 — Direct Emissions
On-site fuel combustion, fleet vehicles, refrigerant losses, and generators. All figures should be annual totals for the reporting period.
Scope 2 — Indirect Energy Emissions
Purchased electricity, district cooling, and renewable energy. Grid emission factor is auto-selected based on your country (Qatar).
Scope 3 — Value Chain Emissions
Upstream and downstream emissions from business travel, employee commuting, purchased goods, waste, and water.

Frequently Asked Questions
We use IEA 2023 grid emission factors for all GCC countries, DEFRA 2024 conversion factors for fuels and refrigerants, and IPCC AR6 GWP values. Factors include diesel (2.71 kgCO2e/L), petrol (2.315 kgCO2e/L), LPG (2.98 kgCO2e/kg), natural gas (2.02 kgCO2e/m3), and country-specific grid factors (e.g., Qatar 0.4896 kgCO2e/kWh). All factors are updated annually.
Carbon Diagnostic Pro includes GCC-specific features not found in generic calculators: district cooling (ton-hours), desalinated water emission factors, country-specific grid factors for all six GCC nations, refrigerant losses with GWP values, and a fleet fuel type selector (petrol/diesel/mixed). The tool also covers five key Scope 3 categories including spend-based procurement emissions.
The free diagnostic provides a screening-level estimate. The Standard and Professional tiers produce ISO 14064-1 compliant GHG inventories. The Verified tier includes GAB-accredited ISO 14064-3 third-party verification.
The free diagnostic covers five key Scope 3 categories: business travel (Cat. 6) with cabin class differentiation, employee commuting (Cat. 7) based on distance and headcount, purchased goods and services (Cat. 1) using the spend-based method, waste (Cat. 5), and water supply. The Professional tier covers all 15 Scope 3 categories.
District cooling is particularly relevant in Qatar and the Gulf. We use an estimated factor of 0.5 kgCO2e per ton-hour, which accounts for the electricity used by the district cooling plant, chilled water distribution, and pump energy. This factor is conservative and suitable for screening purposes. A full inventory would use plant-specific efficiency data.
The free diagnostic results can be printed or saved as PDF directly from the browser using the "Download as PDF" button. Paid tiers include professional PDF reports, Excel data exports, and board-ready presentation templates.
All data is transmitted securely via HTTPS and processed in accordance with Qatar PDPL and our Privacy Policy. We do not share your data with third parties. Assessment data is retained for 12 months unless you request deletion.
