Project Drawdown's research models are uniquely valuable tools for quantifying the potential size and economics of different climate solutions. To enhance their usefulness and application and offer transparency regarding how we quantify projected greenhouse gas and economic costs and benefits, we are releasing these models into the public domain. This process is still in the early stages, and many pieces of software are still under development.  Interested individuals can check out the ongoing work can be accessed on Github, where Python and Excel versions of the models are being worked on, along with user interfaces, data management tools, and other software tools.
