CityCatalyst is an Open Source Web application for managing a city's climate journey. Cities can start tracking greenhouse gas emissions using CityCatalyst from a variety of sectors -- buildings, transportation, waste, agriculture, industry -- in the GHG Protocol for Cities (GPC) format. They can assemble emissions data from different public data sources, including nationally-tracked environmental data, AI models, or satellite data. They can also update their emissions data manually, using well-established methodologies. The reports generated by these emissions inventories can be shown on a public dashboard for citizens or disclosed to investors or international tracking organizations. Upcoming versions of the platform will also include risk assessments (what effect will climate change have on the city?) and action planning (what can the city do to lower risk and emissions). As an Open Source tool, CityCatalyst lowers the costs of climate change tracking and puts power into the hands of cities of all sizes and in all parts of the globe.

CityCatalyst is built using the open source projects React, NextJS, ChakraUI, Tailwind, PostgreSQL, Sequelize, Nivo, Pigeon Maps and many more.
