For this, the amounts of other gases are converted to the amount of CO<sub>2</sub> that would have the same impact on global warming (over a 100-year period).

The formula used for the calculation of the carbon footprint ($C$) is:
The formula used for the calculation of the carbon footprint ($CO_2e$) of one Nextflow task is:

$C = t \cdot (n_c \cdot P_c \cdot u_c + n_m \cdot P_m) \cdot PUE \cdot CI$
$CO_2e = t \cdot (n_c \cdot P_c \cdot u_c + n_m \cdot P_m) \cdot PUE \cdot CI$

**$PUE$** = the efficiency coefficient of the data centre<br/>
**$CI$** = the carbon intensity of energy production, which represents the carbon footprint of producing 1 kWh of energy for a given country and energy mix

For the final CO<sub>2</sub>e estimation of a pipeline run, the values of all cached and completed tasks are summed up.
