Sustainability in Rail Manufacturing: Reducing Carbon Footprints Through Better Procurement
The rail industry has long been recognised as one of the most sustainable modes of transport, but sustainability in rail extends far beyond the operation of trains. Manufacturing processes, materials sourcing, and procurement decisions all have a significant impact on the industry’s carbon footprint. By adopting better procurement practices, rail manufacturers can reduce emissions, promote the use of sustainable materials, and create a greener future for rail.
This blog explores how procurement strategies are shaping the future of sustainable rail manufacturing, supported by real-world data and actionable insights.
Understanding the Carbon Footprint of Rail Manufacturing
Rail manufacturing involves energy-intensive processes and the use of materials like steel and concrete, which have high embodied carbon. According to the International Energy Agency (IEA), the global steel industry accounts for approximately 7% of global CO2 emissions, much of which is driven by infrastructure and manufacturing demands. In rail, tracks, rolling stock, and supporting infrastructure all contribute to this environmental impact.
Procurement decisions can significantly influence these emissions by determining the types of materials used, the energy sources relied upon during production, and the transportation methods involved in supply chains. Rail infrastructure projects alone can account for over 50% of the carbon emissions in a rail system’s lifecycle, making procurement a critical area for reducing overall impact.

The Role of Procurement in Sustainability
Procurement serves as the foundation for a sustainable supply chain, influencing every stage of the manufacturing process. By prioritising sustainable procurement, rail manufacturers can source recycled steel, adopt lower-carbon alternatives like green concrete, and encourage local sourcing to minimise emissions associated with transportation. Additionally, working with suppliers that use renewable energy during production and demand sustainability certifications such as ISO 14001 can significantly reduce environmental impact.
For instance, Deutsche Bahn partnered with suppliers in 2020 to source 100% green electricity for its rail manufacturing processes, reducing CO2 emissions by over 200,000 tonnes annually (Source: Deutsche Bahn, Sustainability Report 2020).
Real-World Strategies for Reducing Emissions
One of the most effective strategies involves integrating recycled materials into supply chains. ArcelorMittal’s XCarb® recycled and renewably produced steel reduces emissions by up to 70% compared to traditional methods (Source: ArcelorMittal, XCarb Product Line). Similarly, prioritising energy efficiency in manufacturing by selecting suppliers with ISO 50001-certified systems can significantly lower energy consumption. Bombardier Transportation, for example, achieved a 19% reduction in energy usage across its facilities by upgrading machinery (Source: Bombardier Sustainability Report, 2021 Highlights).
Lifecycle Cost Analysis (LCCA) also plays a vital role in sustainable procurement. By evaluating environmental impacts across a product’s entire lifecycle, manufacturers can make informed decisions about materials and suppliers that align with long-term sustainability goals.
Using recycled materials in rail track manufacturing alone can lower CO2 emissions by 30-40%, according to the International Union of Railways (UIC, Sustainable Rail Guidelines).
Overcoming Challenges in Sustainable Procurement
Transitioning to sustainable procurement is not without challenges. Cost implications remain a significant barrier, as sustainable materials often carry higher upfront costs. Additionally, supply chain complexity and verifying sustainable practices among suppliers can require substantial resources. Resistance to change within organisations also poses difficulties, particularly among stakeholders unfamiliar with sustainability initiatives.
However, these challenges can be mitigated through collaboration and technology. Rail companies can join initiatives like the Rail Industry Decarbonisation Taskforce to foster industry-wide collaboration toward net-zero goals. Digital tools, powered by AI, can streamline supplier evaluations and track emissions across supply chains. Furthermore, training procurement teams and incentivising suppliers to meet environmental benchmarks can encourage widespread adoption of sustainable practices.
The Future of Sustainable Rail Manufacturing
The future of rail manufacturing lies in embracing circular economy practices, increasing the reuse and recycling of materials at the end of their lifecycle. Green certifications will become a standard requirement for suppliers, while AI-driven tools will enable real-time tracking of supply chain emissions, facilitating agile and informed procurement decisions.
The global green procurement market is projected to grow at a CAGR of 6.8% from 2022 to 2030, reflecting the rising importance of sustainable practices. Rail manufacturers that invest in better procurement strategies today will be well-positioned to meet future regulatory requirements and consumer expectations.
