The Transition Element Framework

A trusted and widely adopted model enabling governments worldwide to use
standard Transition KPIs for systemic decarbonisation. Open to the world.

An open source initiative.

The Transition Element Framework (TEF) is ClimateView’s open-source initiative, making knowledge from the IPCC actionable. Built on decades of climate science and grounded in real-world application, the TEF provides a standardized, structured framework that enables cities, regions, and nations to embrace their sustainability transitions with confidence.

By giving national and subnational governments access to a common language for setting transition KPIs, the TEF ensures that climate mitigation strategies are measurable, comparable, and tailored to local needs. Whether you're driving decarbonization at the city, regional, or national level, the TEF helps translate sustainability ambitions into measurable progress.

Built on science.

The TEF is based on IPCC mitigation strategies, providing governments with the tools to establish robust KPIs that track climate progress effectively. By summarizing and structuring IPCC knowledge into clear building blocks, the TEF enables actors to measure and manage the transition with data-driven insights. The open-source nature of the TEF means it's accessible to all, empowering cities, regions, and nations to build their own tailored decarbonization strategies.

Trusted. Used. Proven.

The TEF isn’t just theory—it’s a proven system, already in use by hundreds of cities worldwide. From 32 local authorities in Scotland to 54 cities in Germany’s Ruhr region, and with 500 sub-national governments set to adopt it through our partnership with ICLEI USA, governments are using the TEF to guide their sustainability transitions.

By connecting cities and governments under a shared framework of transition KPIs, the TEF enables cities to collaborate, track, and accelerate their progress and to build collective knowledge toward systemic decarbonization.

Resources for cities
 and regions.

Our open-source approach means that we work transparently, sharing data, models, and case studies that support all actors in the sustainability space. Access these resources to learn more about how cities and regions are using the TEF to make informed decisions, measure their impact, and achieve their sustainability goals.
