Diesel CO₂ Calculator
Convert diesel (l) use into tCO₂e and annual fuel spend — IPCC factors.
Every litre of diesel releases 2.68 kg CO₂e — generators, trucks, pumps, it doesn't matter where it burns. Enter your monthly quantity and price; the result pairs the tonnes with the spend so reduction projects can quote both.
Every litre of diesel releases 2.68 kg CO₂e — generators, trucks, pumps, it doesn't matter where it burns. Every unit of diesel (l) burned releases 2.68 kg CO₂e (IPCC default, combustion only). Fuel emissions and fuel bills fall together — the business case and the carbon case are the same case.
Screening-level estimate using published average emission factors. Audited disclosures (BRSR, GRI, CDP) require primary activity data and verified factors — confirm with your sustainability auditor.

Frequently asked questions
How much CO₂ comes from a litre of diesel or petrol?+
Diesel: 2.68 kg CO₂e/L; petrol: 2.31; LPG: 2.98/kg; CNG: 2.75/kg; coal: ~2.42/kg (grade-dependent) — IPCC combustion defaults. Multiply by your purchase volume and the Scope 1 line writes itself. The carbon is fixed chemistry; only the volume is negotiable.
Why track fuel emissions monthly instead of annually?+
Because fuel is bought monthly and decisions are made monthly: a generator running long this month shows up now, not in a year-end surprise. Monthly lines also build the evidence trail (invoices ↔ entries) that assurance and audits sample.
What's the fastest way to cut fuel emissions?+
Displace, then improve: solar+storage against generator hours, electric against ICE kilometres, heat pumps or biomass against boiler fuel — displacement zeroes the line. Where the fuel must stay, maintenance and load management deliver the 10–20% the reduction row prices.
Do these factors include upstream (well-to-tank) emissions?+
No — combustion only, the Scope 1 convention. Upstream extraction/refining/transport adds ~15–25% but belongs in Scope 3 category 3. Keep the boundaries clean: this number is defensible precisely because it claims only what your chimney emits.
