Per process emissions

The plot shows the distribution of CO₂e emissions and corresponding energy consumptions for each workflow process. The values that are displayed when hovering over the plot refer to the CO2e emissions.

Carbon intensity & energy usage timeline

This plot shows the fluctuation of carbon intensity (CI) during workflow computation and the energy consumption of individual tasks. Together, these two factors determine the emitted CO₂e.

Tasks

(tasks table omitted because the dataset is too big)

This table shows information about each task in the workflow. Use the search box on the right to filter rows for specific values. Clicking headers will sort the table by that value and scrolling side to side will reveal more columns.

Options

This table shows the nf-co2footprint plugin options that were used to calculate the CO₂e footprint estimations.
