Sweep (sweep.net) is an AI-powered developer tool that automates the process of fixing bugs, implementing features, and optimizing code by generating pull requests directly in GitHub repositories. While marketed for general code improvement, it has no dedicated features for measuring, tracking, or reporting carbon footprints or environmental impact. Any potential benefits for carbon reduction are indirect, stemming from possible performance optimizations that could lower computational energy use, but it lacks Scope 1-3 emissions calculations, sustainability dashboards, or compliance reporting typical of true carbon footprint software.

Normative (normative.io) is a comprehensive carbon accounting platform that automates the measurement, reporting, and reduction of Scope 1, 2, and 3 greenhouse gas emissions for businesses. It integrates with ERP systems, spend data, and supplier information to deliver audit-ready calculations and science-based insights. The platform supports compliance with standards like CSRD, CDP, and SBTi, while providing dashboards for strategic decarbonization planning.

Greenly is an AI-powered carbon management platform that automates the calculation of Scope 1, 2, and 3 emissions for businesses by integrating with accounting, ERP, and other data sources. It provides real-time dashboards, reduction recommendations, and compliance-ready reports for standards like CSRD, CDP, and SBTi. The tool emphasizes spend-based methodology for accurate Scope 3 tracking and supports offsetting through verified projects.

Terrascope is a sustainability platform focused on helping organizations measure, manage, and reduce their carbon footprint, with a strong emphasis on automated tracking of cloud emissions from AWS, Azure, and GCP. It provides real-time dashboards, emissions forecasting, scenario modeling, and actionable recommendations to optimize cloud usage for lower emissions. The tool also supports broader sustainability reporting, goal tracking, and integrations for Scope 1, 2, and 3 emissions, making it suitable for tech-driven companies aiming for net-zero goals.

Plana (plana.earth) is a mobile-first app designed for individuals to track their personal carbon footprint by logging activities in categories like transportation, food, energy, and shopping. It calculates emissions using established methodologies and offers personalized insights, reduction tips, and progress visualizations. The platform emphasizes behavioral change through gamified challenges, leaderboards, and community features to make sustainability engaging.

Climatiq is an API-first platform offering access to over 190,000 verified emission factors from sources like DEFRA, EPA, and BEIS for precise carbon footprint calculations across activities such as travel, energy use, and supply chains.
