Emission factor from SEMARNAT

Electric power generation, transmission and distribution - Crude oil (production average)

Mexico · Combustion · Any year

Each kilowatt-hour of this fuel counts as 0.265 kg CO₂e from burning it. open-climate.ai worked this figure out from values published by SEMARNAT, for use in any year.

Where 0.265 comes from

Derived by open-climate.ai

open-climate.ai adds up the gases SEMARNAT publishes, each weighted by its warming potential.

Reporting this kilowatt-hour under the GHG Protocol

Scope 1 0.265

You burn the fuel, so its combustion is your Scope 1.

What this number covers

The path of one kilowatt-hour of this fuel, from the well to your flame.

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
0.265

= 0.265 per kWh

Outside this boundary

Producing and delivering the fuel
Making the boiler that burns it
Building the pipelines and the network

SEMARNAT counts only burning the fuel, not producing and delivering it or the things built to extract, move and burn it.

Gases

Basis: Excl. biogenic CO₂FossilBio CH₄Land useBio CO₂GHG Protocol and IPCC inventories

Fossil CO₂0.26499.7%
Nitrous oxide (N₂O)0.000590.2%
Methane (CH₄)0.0003220.1%

Σ 0.264 + 0.000322 + 0.00059 = 0.265.

Each gas is converted to CO₂e with AR6 100-year warming potentials; biogenic CO₂ and land-use carbon are left out, while methane from biogenic sources is counted.

From SEMARNAT's record to a comparable factor

SEMARNAT publishes the inputs; open-climate.ai computed this value from them. Here is each field as printed and what open-climate.ai made of it.
