Thrive Trust 

C3 Group is proud to be the strategic net zero partner for Thrive Co-operative Learning Trust, supporting their schools in delivering impactful carbon reductions, long-term cost savings, and meaningful environmental change. Together, we’re transforming classrooms, leadership culture and infrastructure across the Trust.

Watch the video below to hear from Paul at Thrive about our partnership and the incredible work we’ve done together to support their journey to Net Zero.

Project Overview

A Strategy for Long-Term Sustainability

Thrive Trust, which includes 10 schools across Hull, wanted to take decisive action on carbon emissions and energy costs. C3 Group brought deep expertise in education-sector decarbonisation, forming a partnership focused on delivering fundable upgrades, ongoing evaluation, and a clear roadmap to net zero.

What We Did

Data-Driven Upgrades and Measurable Results

We helped the Trust implement practical solutions across multiple school buildings – backed by energy assessments, detailed ROI modelling, and a long-term vision for continual progress.

Scope of Work:
  • 4,403 LED panels installed, reducing electricity demand
  • £222,441.59 in energy cost savings to date
  • 104.3 tonnes of CO₂e emissions avoided
  • 3.33 years average ROI across projects

Beyond delivery, we’re guiding the Trust through setting clear targets, tracking milestones, and refining strategies to maximise long-term results.

The Results

Lighting the Path to Net Zero

By prioritising low-disruption, high-impact interventions like LED lighting, Thrive Trust is already seeing results – lower bills, reduced emissions, and stronger internal accountability around sustainability goals.

And we’re not done yet. Our partnership supports a continuous improvement approach, adapting and scaling strategies as the Trust evolves.
