Each kilowatt-hour of this fuel counts as 0.402 kg CO₂e: 0.346 from burning it and 0.056 for producing it and bringing it to you (estimated).

EstimatedAn estimate by open-climate.ai, not a number the publisher printed. Where a fuel publisher prints combustion only, we add the supply chain before the burn (well-to-tank), computed by one stated rule from the publisher's own combustion value and a published supply-chain ratio.

Σ 0.402: open-climate.ai adds up the two parts. ČHMÚ prints fuel combustion. open-climate.ai estimates fuel supply from other published figures.
Reporting this kilowatt-hour under the GHG Protocol
Scope 1 0.346 Scope 3, category 3 0.056
You burn the fuel, so its combustion is your Scope 1.
Supplying the fuel is Scope 3, category 3 for whoever burns it.

- BoundaryWell-to-useOne unit of energy as consumed, priced from the well to the point of use: the well-to-tank chain plus the burn for a fuel; generation, its well-to-tank and the transmission and distribution losses for a delivered carrier (electricity, steam or hot water, chilled water).

- Fuel supply and fuel combustion
- GWP methodWhich IPCC assessment report's warming potentials convert each gas to CO₂e, and over how many years the warming is counted (GWP100: 100 years). Learn more
- IPCC AR5, 100-year horizon
- Not on the record; set from ČHMÚ's method notes
- CO₂e basisWhich carbon the CO₂e counts. Fossil only leaves out biogenic methane, land-use change and biogenic CO₂; excl. biogenic CO₂ counts biogenic methane but not the other two; net total counts every pool, net of removals. The same activity on two bases is two different numbers. Learn more

What this number covers
The path of one kilowatt-hour of this fuel, from the well to your flame. ČHMÚ gives one figure for the first three steps together.
Well-to-tank0.056Scope 3, cat. 3
Extraction
Getting the fuel out of the ground
Processing
Treating it to the quality it is sold at
Transport
Moving it to your site
Your meter
1 kWh used. The factor is per kWh measured here.
Burning it
In your boiler, furnace or engine: CO₂, with a little CH₄ and N₂O
Scope 10.346
0.056 + 0.346 = 0.402 per kWh
Outside this boundary
- Making the boiler that burns it
- Building the pipelines and the network
ČHMÚ counts the fuel, not the things built to extract, move and burn it.
Gases
ČHMÚ publishes this factor as CO₂e only, with no split by gas. The CO₂e counts fossil carbon only; biogenic CO₂, biogenic methane and land-use carbon are left out.
From ČHMÚ's record to a comparable factor
ČHMÚ publishes one of the two parts; open-climate.ai estimated the others and added them all up to this total. Here is each field as printed and what open-climate.ai made of it.
The total and its parts
Each part has its own page. Use a part on its own when you report Scope 1 and Scope 3 separately; never add a part to the total.
