Optima Educating the Supply Chain
The Challenges
Optima’s journey toward net zero began five or six years ago, but they faced uncertainty about the true environmental impact of their business and products. Aluminium’s high carbon footprint created pressure, but sustainable alternatives weren’t clear.
Tunley Environmental started working with Optima back in 2017, helping to measure company-wide and product emissions, improve product performance, and educate the supply chain, and even supporting one supplier to achieve net zero. This evidence-based approach allowed Optima to make informed, credible sustainability decisions and lead their sector in low-carbon solutions.
Our Approach
Tunley Environmental supported Optima with comprehensive carbon measurement and lifecycle assessments across their organisation and products. This data revealed that while virgin aluminium is carbon intensive, high-recycled-content aluminium offers a significantly lower-impact alternative.
Working together, Optima secured access to 75% post-consumer recycled aluminium, dramatically reducing embodied carbon while retaining the performance and circularity benefits of aluminium.
The Impact
Through our ongoing partnership, Optima has:
-
Embedded sustainability across the business, with board-level oversight
-
Reduced company and product emissions
-
Published 30+ Environmental Product Declarations (View their published EPDs)
-
Invested in renewable energy, heat recovery, and cleaner transport
-
Launched take-back and reuse schemes to support circularity
-
Expanded focus beyond carbon to include biodiversity, water, and CSRD readiness
The Result
Optima is now recognised as a sustainability leader in their sector, outperforming key competitors based on publicly available environmental data. Their approach is grounded in evidence, integrity, and continuous improvement.
