The tools built by Avoin in collaboration with TalTech apply a hybrid method combining the GHG Protocol and environmentally extended input-output (EEIO) models, ensuring comprehensive and accurate coverage of emissions. Built in English and Estonian and hosted by TalTech, the tools integrate local emission factors, open APIs, and accounting data, enabling organisations to evaluate climate impacts and support national climate strategies. The project also laid the foundation for a long-term partnership with companies and academia.
