Description:The nf-co2footprint plugin integrates with Nextflow pipelines to calculate and report the energy consumption and CO₂ emissions of workflow runs by analyzing task resource metrics and carbon intensity data. It solves the problem of environmental impact visibility by generating detailed HTML and text reports with per-task breakdowns and pipeline-wide visualizations. This plugin is used by bioinformaticians and computational researchers who want to measure and optimize the carbon footprint of their scientific workflows.
