The document discusses approaches for making software development more environmentally sustainable, referred to as "green coding" or "eco-coding". It outlines code smells and inefficiencies that can negatively impact energy usage and device lifespan. It then introduces ecoCode, an open source plugin for the SonarQube platform that helps developers identify such issues through static analysis and provides metrics to track sustainability improvements over time. The document argues ecoCode can help establish best practices for green software development while avoiding limitations of existing tools through its community-driven approach.
