January 2025 – CityCatalyst (Open-Earth-Foundation/CityCatalyst) delivered targeted bug fixes and enhancements with clear business value. Core calculations were stabilized (ON-3049/ON-3143; methane commitments for ON-2950/2830/3113; accurate MCF and CH4 emissions for domestic wastewater). Reporting accuracy improved through fixes to CSV units and updated XLSX outputs. Data and formulas were strengthened (city included in inventory value to improve formula input filtering; FAO_stat data integration; domestic waste formula corrections; industrial waste formula corrections). Localization and consistency improvements were introduced (localize emissions entries on all tables) along with code cleanups and configuration updates. A performance validation run via load testing on-2688 informed capacity planning, with revert actions executed where required to maintain stability.
