Open-source analytical tools for energy transition and decarbonization.
Net Zero Horizon is a collaborative initiative that develops and maintains open-source software to support the global shift toward carbon-neutral energy systems. Our tools are designed for researchers, engineers, and policymakers working on renewable energy assessment, system planning, and decarbonization pathways.
