Understanding the STI Next commitments

STI EngagedSTI ShaperSTI LeaderSTI Champion

Programme status. Each participant carries a programme status that reflects the overall progress of its commitments: Engaged (commitments taken, work starting), Shaper (concrete measures under way), Leader (ambitious commitments largely delivered), Champion (the highest level, all commitments achieved and renewed). This status evolves over time.

Level 1 Level 2 Level 3

Pledge levels. Every pledge is classified by ambition level, from 1 to 3, shown as dots next to its thematic. Level 1: a first, foundational commitment. Level 2: a concrete, measurable action with a defined target and timeline. Level 3: the most ambitious commitment, structural and verified against recognised standards.

In progressAchievedDelayed

Progress. Each pledge shows its progress: In progress (work under way within the agreed timeline), Achieved (target reached and validated), Delayed (timeline extended). Alumni companies keep their last recorded pledges and levels.
