GRS Roadstone
Britain's leading trader, transporter and handler of construction materials, building products and waste materials, plus associated construction solutions.
Una’s AI-driven insights gave us a roadmap to decarbonise, helping us measure and maximise the ROI of our sustainability initiatives while reducing costs
GRS Roadstone, one of the UK’s largest suppliers of aggregates, waste removal, and bulk transport services, sits at the heart of the construction industry’s sustainability transition. With a vast network of 2,000+ suppliers and buyers, GRS needed full transparency over its emissions to drive meaningful decarbonisation—without sacrificing financial performance or operational efficiency.
The Problem
Despite early investments in fleet electrification and low-carbon materials, GRS faced three major roadblocks in scaling its sustainability efforts:
🔍 Lack of Supply Chain Visibility – With thousands of suppliers contributing to its Scope 3 footprint, GRS needed real-time, data-driven insights to measure, manage, and engage its supply chain on emissions reduction.
💰 High Cost of Decarbonisation – GRS sought government grants, subsidies, and financial incentives to ease the financial burden of sustainability investments.
📊 Prioritising the Right Climate Actions – With multiple initiatives in motion, GRS needed a clear roadmap to ensure every action maximized both environmental and financial ROI.
The Solution: AI-Powered Climate Action at Scale
🚀 Supply Chain-Wide, Central Carbon Intelligence
- Una built Adaptive Carbon Profiles (ACP) for over 2,000 suppliers and buyers, instantly quantifying emissions across all three scopes.
- GRS gained a clear, data-backed view of supply chain emissions, identifying high-risk suppliers and engaging them to take action.
- Automated insights helped GRS accelerate Scope 3 reductions by encouraging supplier participation in sustainable practices.
💡 Unlocking Grants & Financial Incentives
- Una pinpointed government subsidies and industry grants available to GRS and its suppliers, significantly lowering the cost of decarbonisation.
- Verified emissions reductions allowed GRS to monetise carbon savings through voluntary carbon markets, turning sustainability into a profit-enhancing strategy rather than a cost.
