Low Embodied Carbon and ESG in Construction
Reducing carbon emissions is now a core objective for many organisations, and the construction sector has a significant role to play. Embodied carbon refers to the emissions generated across the entire lifecycle of a building material; from raw material extraction and manufacturing to transport, installation, maintenance, and eventual end-of-life processing.
Selecting materials and construction processes that lower embodied carbon is a practical and measurable way for businesses to support their ESG commitments. Fortunately innovation in materials and supply chains is rapidly improving the construction industry’s image in environmental issues.
How is Embodied Carbon Reduced?
Methods to reduce embodied carbon typically include:
- Using recycled steel to reduce reliance on carbon-intensive raw materials (World Steel Association – Sustainability)
- Implementing energy-efficient production technologies
- Increasing the use of renewable energy in manufacturing
- Improving supply chain efficiency to cut transport-related emissions
The objective is to minimise the overall carbon footprint of steel production while maintaining the strength, durability, and performance that it is known for. Further guidance on measuring and reporting embodied carbon can be found via the UK Green Building Council.
Why Steel Frame Construction Can Reduce Embodied Carbon
Industry research, including guidance from organisations such as The Institution of Structural Engineers, highlights the importance of assessing materials across their full lifecycle rather than focusing solely on upfront emissions.
Given this, it’s interesting that one of steel’s key advantages is its longevity. It’s a highly durable material with a long service life, which reduces the need for frequent repairs, replacements, or complete rebuilds. This extended lifespan is a critical factor in total embodied carbon calculations.
In addition, steel is:
- Fully recyclable without loss of quality
- Frequently reused at the end of a building’s life (WRAP – Metals and Recycling)
- Manufactured with high precision, reducing material waste
- Lightweight, which can help lower transportation emissions
When assessed over the full lifecycle of a building, steel frame construction can deliver meaningful environmental benefits.
Responsible Supply Chains and Sustainable Construction
The construction industry is continuously seeking ways to reduce its environmental impact, and responsible sourcing is central to this effort. Working with trusted suppliers who actively reduce emissions across their operations helps ensure that sustainability goals are achieved. At Carnegie, we take this responsibility seriously by prioritising strong relationships with suppliers who share our climate goals.
Looking Ahead
As regulations evolve and ESG expectations continue to rise, low embodied carbon materials will become a standard requirement rather than a future ambition. Steel frame construction offers a proven, scalable solution that balances structural performance with environmental responsibility. This is helping to shape a more sustainable future for the built environment.
