PB Design Building Structure from Scratch
The Challenges
When PB Design first approached Tunley Environmental in 2022, they had no environmental expertise or systems in place on-site. With increasing pressure from customers and suppliers to demonstrate sustainability, they needed a way to measure and report their carbon emissions, set achievable goals, and integrate environmental responsibility into their business strategy.
Our Approach
Tunley Environmental partnered with PB Design to provide a structured sustainability framework. This included conducting both business carbon assessments and embodied carbon assessments, as well as a 12-month retainer for ongoing carbon reporting. We guided PB Design through the process of measuring emissions, interpreting results, and setting realistic sustainability targets, ensuring they had continuous support and expert advice throughout the journey.
The Impact
Through our ongoing partnership, PB Design has:- Gained a clear understanding of their carbon footprint and a roadmap for improving their environmental performance
- Create accurate ESG and carbon reports while building credibility with customers and suppliers
- Make informed decisions about sustainability initiatives.
The Result
PB Design now receives annual ESG and business carbon assessment reports that are timely, accurate, and within budget. They have clear, actionable sustainability goals and feel supported and prioritised in their environmental journey. The collaboration has enabled them to strengthen relationships with stakeholders, enhance their market positioning, and confidently communicate their sustainability achievements.
