Leveraging Open Source Tools for Enhanced Climate Transition Analytics

We discuss what open source software offers international organisations engaged in project finance and technical assistance in low- and middle-income country (LMIC) contexts with a focus on energy tools. The benefits include the low initial cost, the ability to leverage an existing community of active developers, the possibility for independent experts and academics from LMICs to reshape parts to include indigenous Summary knowledge, and the option to extend or use an existing tool rather than developing in-house. With open source, international organisations can benefit from and influence the growing ecosystem of open source energy and climate models to enhance transparency, improve decision-making processes, and reduce costs, while remaining adaptable to the evolving regulatory landscape.
