LeafByte

LeafByte is a Chrome extension provides real-time CO₂ monitoring via dynamic dashboards, gamification, privacy-focused local storage & developer utilities. Emissions are calculated through the Performance API as data transfer × energy/byte × carbon intensity, using defaults of 475 g CO₂/kWh and 0.5 kWh/GB, with a 50% reduction applied to green-hosted sites. All processing occurs locally without external APIs, providing accurate insights into energy use, carbon intensity, and digital footprint.
