The reporting process of Greenhouse Gas (GHG) emissions in Indonesia remains largely manual, resulting in inefficiencies and inaccuracy, especially within the industrial sector. This study introduces an IoT-based integrated system to automate data acquisition, calculation, and Scope 1 emission reporting. Utilizing MQTT protocol, the system collects real-time CO₂ and CH₄ sensor data, stores it in the ThingSpeak platform, and transfers it to a Laravel database for automated reporting. An iterative-incremental model was applied for development. Functional testing and expert validation confirmed the system's ability to operate continuously and generate reports aligned with national GHG standards.
