In today’s rapidly evolving sustainability and energy efficiency landscape, partnerships and collaboration have never been more important. No organisation can tackle the complex challenges of carbon reduction, energy optimisation, and climate resilience alone. The most effective solutions come from working together, leveraging expertise, and embracing data-driven decision-making.
At epx, we’ve seen how powerful collaboration can be in delivering real sustainability outcomes. Our recent win at the edie Awards 2025—taking home Partnership and Collaboration of the Year—is proof of what’s possible when organisations work together toward a shared goal.
Through our partnership with Westfield, Schneider Electric, and ISS, we’ve achieved:
- Over 20% energy savings at Westfield London
- More than 3,000 tonnes of CO₂ emissions reduced since 2021
Why Collaboration Matters in Sustainability
Sustainability projects require expertise across multiple domains—technology, engineering, operations, and strategy. By combining forces with Westfield, Schneider, and ISS, we ensured every initiative was:
- Technically sound
- Operationally feasible
- Backed by real-time data
This approach helped us make informed decisions that balanced sustainability with performance.
