Carbon-intensity factors used in the map are detailed in co2eq_parameters.json. These numbers come mostly from the following scientific peer reviewed literature: IPCC (2014) Fifth Assessment Report is used as reference in most instances (see a summary in the wikipedia entry). The IPCC report where the values can be found is here.
Here is an overview of the default emission factors used:
| Mode | Emission factor (gCO2eq/kWh) | Category | Source |
|---|---|---|---|
| battery discharge | 301 | Renewable (default) | World average intensity by electricityMap |
| biomass | 230 | Renewable | IPCC 2014 |
| coal | 820 | Fossil | IPCC 2014 |
| gas | 490 | Fossil | IPCC 2014 |
| geothermal | 38 | Renewable | IPCC 2014 |
| hydro | 24 | Renewable | IPCC 2014 |
| hydro discharge | 301 | Renewable (default) | World average intensity by electricityMap |
| nuclear | 12 | Low-carbon | IPCC 2014 |
| oil | 650 | Fossil | IPCC 2014 |
| solar | 45 | Renewable | IPCC 2014 |
| unknown | 700 | Fossil | Assumes thermal (coal, gas, oil or biomass) |
| wind | 11 | Renewable | IPCC 2014 |
