As we continue our Knowledge Transfer Partnership (KTP) with Aston University, Metal Assemblies is strengthening its commitment to sustainable manufacturing across carbon transparency, social impact, operational efficiency and environmental responsibility.

This work is shaping the foundations for our long-term sustainability strategy and ensuring we remain ahead of incoming regulations such as the Carbon Border Adjustment Mechanism (CBAM).

Carbon Border Adjustment Mechanism (CBAM)
To support upcoming CBAM requirements, we have been working closely with our suppliers and customers to improve carbon transparency and develop accurate embedded emissions data for the products we manufacture.

This has enabled us to produce tentative carbon cost figures for two products using supplier-provided data. In an example for a major automotive OEM, we calculated an embedded carbon value of 0.83 kgCO2e per pressed assembly, with around 98% of emissions linked to Scope 3 activities such as raw materials and transport, and 2% attributed to our internal operations, reflecting our negligible Scope 2 impact due to the use of zero-carbon electricity.

Social Sustainability
As part of our social sustainability work, we have been building a strong foundation of knowledge and awareness across Metal Assemblies and our value chain.

This includes taking part in the Aston Green Advantage programme to develop skills in the green transition and carbon measurement, delivering presentations to management, team leaders and suppliers to explain sustainability and CBAM, and sharing regular project updates with staff to promote transparency. Alongside this, the team is developing our Sustainable Manufacturing Strategy, with the first output being a new Sustainability Policy.

Economical Sustainability
In our environmental sustainability work, we have established a clear understanding of our Scope 1, Scope 2 and selected Scope 3 emissions, giving us a full picture of our carbon footprint and helping us track progress towards low-carbon manufacturing.

We are also exploring on-site solar panels to reduce reliance on the grid, lower energy costs and increase our share of renewable electricity, building on our current use of 100% zero-carbon energy from nuclear and renewables.

Environmental Sustainability
We have strengthened our understanding of our Scope 1, Scope 2 and selected Scope 3 emissions, giving us a clear view of our overall carbon footprint and helping us monitor progress towards low-carbon manufacturing.

In response to rising energy costs, we are also exploring installing solar panels to reduce grid reliance, lower operational costs, and increase our share of renewable electricity, complementing our existing use of 100% zero-carbon energy.

Together, these updates reflect the steady progress being made across the KTP project and our wider commitment to becoming a more transparent, efficient and environmentally responsible manufacturer.
