Corporate carbon footprint calculator
Build your company’s GHG inventory line by line across all three scopes: fuels and vehicles (Scope 1), purchased electricity (Scope 2, with the official Türkiye grid factor) and the value chain (Scope 3). Tag every row by data quality and see not just a number, but how ready you are for verification. Runs in your browser — no sign-up.
Factors: Türkiye Ministry of Energy consumption-point factor (2021 data, March 2024 form) + DEFRA/DESNZ 2025. Last checked: 6 September 2026.

Most SMEs use operational control: you report 100% of emissions from operations you control.
Scope 1 — Direct emissions
Fuel burned on site or in your own vehicles, and refrigerant leaks from your own equipment. Take quantities from utility bills, fuel receipts and maintenance records.
Scope 2 — Purchased energy
Electricity you purchase. The location-based figure uses the Türkiye Ministry of Energy consumption-point factor — transmission and distribution losses included.
For the market-based memo line: certified kWh are deducted there; the location-based headline is unchanged (GHG Protocol dual reporting).
Scope 3 — Value chain
Line-item calculators for the four categories that dominate most SME inventories: business travel, commuting and homeworking, and operational waste. Then screen all 15 categories — GHG Protocol expects even a "not material" decision to be recorded.
Business travel (Category 6)
Employee commuting & homeworking (Category 7)
Waste generated in operations (Category 5)
15-category screening
Categories covered by the calculators above are marked automatically. Decide on the rest: not material, relevant with no data, or relevant with your own estimate? "No data yet" is an honest answer — it shows in the report as an estimation gap rather than silently counting as zero.

You have the number — now let’s make it defensible.
Data collection structure, factor choices, boundary decisions and verification readiness: let’s take your inventory to disclosure quality, through a verifier’s lens.

Framework: the calculation follows the scope structure of the GHG Protocol Corporate Standard. The same inventory logic serves companies reporting under Türkiye’s TSRS (ISSB-aligned) and suppliers answering CSRD/ESRS E1 data requests from EU customers; this tool builds your working inventory — it does not replace independent verification (ISO 14064-3) before disclosure.
Electricity factor: the Türkiye Ministry of Energy’s consumption-point emission factor form (ETKB-EVÇED-FRM-042 Rev.01, 12 March 2024; 2021 data): 0.479 tCO₂e/MWh for distribution-connected consumers, 0.445 for transmission-connected — T&D losses included. We update this page when the Ministry publishes a new form.
Other factors: the official UK DESNZ/DEFRA 2025 set (v1.0, 10 June 2025): fuels, vehicles, flights, hotel stays (Türkiye row: 32.1 kg CO₂e/room-night), waste and homeworking — the most widely accepted open factor set in corporate reporting. Refrigerant GWPs follow IPCC AR5. If official Türkiye-specific fuel factors are published, they take precedence.
What this tool does not do: it produces no spend-based Scope 3 estimates (explained above), no product carbon footprints (ISO 14067) or EPDs, and no assurance. The result is an informational working inventory; any externally disclosed figure must pass independent verification.
How is a corporate carbon footprint calculated?
A corporate carbon footprint is the CO₂-equivalent total of the greenhouse gas emissions a company causes, directly and indirectly, in a reporting year. The shared international language is the GHG Protocol, which groups emissions into three scopes: Scope 1 covers fuel you burn and leaks from your own equipment; Scope 2 covers purchased electricity and heat; Scope 3 covers the rest of your value chain, from procurement and business travel to waste and the use of your products.
For companies in Türkiye this is no longer a voluntary exercise. TSRS brings ISSB-aligned sustainability reporting to large companies; every producer selling to EU customers sees supplier data requests driven by CSRD; and CBAM has tied emissions data directly to cost for steel, aluminium, cement and fertiliser exports. Every chain ends at the same question: how many tonnes does your company emit, and on what data do you say so?
Two things decide the quality of the answer: the source of the factors and the quality of the data. Using Türkiye’s official consumption-point electricity factor is materially different from using a generic global average. And a value read from an invoice does not carry the same weight as a rough guess, even inside the same inventory — which is why every row in this tool is stored with a data-quality tag, and the results screen shows openly how much of your inventory rests on measurement. That is the first thing a verifier looks at.
Frequently asked questions
Can I use this for TSRS reporting?
To build your working inventory and organise the numbers, yes. Figures disclosed under TSRS must be checked against your company boundaries and pass assurance — the tool does not replace that, but it hands you a line-by-line documented starting point for it.
Why does the Türkiye grid factor rest on 2021 data?
The Ministry’s most recent official form (March 2024 revision) is based on production year 2021. We will update the tool when a newer official form is published — we prefer a citable official value over unofficial estimates.
Location-based vs market-based Scope 2 — what’s the difference?
Location-based uses the country’s average grid factor; market-based reflects certified purchases such as YEK-G/I-REC. GHG Protocol asks for both; this tool headlines the location-based figure and shows market-based as a memo line when you enter certified kWh.
Does homeworking really count?
Yes — under Scope 3 Category 7. The tool uses DEFRA’s homeworking factor (heating + equipment, per FTE-hour). In a fully remote company this line can replace office electricity as the main item.
