TransitionZero is a climate tech non-profit, founded in 2021 and registered as a charity, that develops open-source energy transition tools. The organisation's mission is to reduce the time required to build clean energy at scale by supporting a global standard for energy transition planning data. It is headquartered in London, with a geographic focus that extends to the Global South.
The organisation's technical work spans energy system modelling, power system analysis, and capacity expansion modelling. Its primary product, Scenario Builder (TZ-SB), is a no-code platform that allows policymakers, planners, and investors to build, analyse, and share energy system models without requiring coding expertise. The tool is designed to accelerate decision-making in government planning and utilities sectors.
TransitionZero is funded through grants and partnerships rather than traditional venture capital. The team operates at the intersection of climate technology and open data, serving stakeholders across the energy transition ecosystem.
