Sustainability 

At British Steel, we're committed to sustainable steelmaking. Steel is vital to modern economies and over the coming decades, global demand is expected to grow to meet rising social and economic welfare needs.

As the world’s most recycled material, steel plays a central role in transitioning to a low-carbon, circular economy. Reviewing our processes and investing in new technology will boost our contribution to significant decarbonisation.

British Steel Low-Carbon Roadmap - answering the climate emergency

British Steel’s ambition is for low-embedded carbon steel production with a phased reduction of CO2 intensity by 2035 and 2050. Our Low-Carbon Roadmap will deliver net zero steel by 2050 and significantly reduce our CO2 intensity by 2030 and 2035*1. We will adopt a science-based target (SBTi)*2 in order to validate the reductions achieved to keep global warming well below 2°C and pursue efforts to limit warming to 1.5°C.

To help achieve these targets British Steel will use a range of techniques and innovations including:

  • Steel product innovation to promote the material benefits to end users, for example through light weighting and life extension
  • Supporting recycling and reuse
  • Deploying circular economy and material efficiency methodologies
  • Assessing and adopting several technology options including Carbon Capture and Storage, hydrogen, increasing scrap utilisation and Electric Arc Furnace steelmaking
  • Our Low-Carbon Roadmap is achievable with appropriate supporting government policies. British Steel continues to engage with government to ensure the correct policies are adopted to achieve carbon reductions
  • Adopting a science-based target initiative to play our part in limiting global warming to well below 2°C above pre-industrial levels and pursue efforts to limit warming to 1.5°C

British Steel’s Low-Carbon Roadmap to achieving aggressive emissions reductions is achievable within the ambitious timescales of the UK government. However, successful implementation of this Low-Carbon Roadmap requires appropriate government support through policies and frameworks.

Life cycle assessment

Steel from the blast furnace route can be easily recycled through the Electric Arc Furnace (EAF) or Basic Oxygen Steelmaking (BOS) route later in its life. In this way a symbiosis between the world’s 2 leading steelmaking routes exists.

Our Environmental Product Declaration (EPD) for rail, sections and semi-finished long products includes the future benefit of the 100% recyclability of steel in the form of a module D assessment. Downstream uses of the British Steel EPD should use module D when evaluating steel products to reflect the unique properties of steel as a ‘multi-generational’ material and a material fully embedded in circular economy thinking.

Supporting your scope 1 emission reductions

Steel is a fast, safe construction material. Steel frames can be manufactured offsite in a safe factory environment. Reducing assembly time on site (7% to 15% less) means lower costs and less disruption to the local community.

Steel construction products can help deliver reductions in scope 1 and 2 carbon emissions for the construction sector.

Through research and development, our innovative S460M structural steel grade can offer a much reduced weight, offering an embedded carbon reduction for your building project.

There is generally no site waste, but any that occurs can be returned to the steel supply chain and multi-cycled. Due to the strength of steel, buildings can be designed with long spans to offer flexible design solutions and extended life. 

Process gases: reduced use of natural gas

At our Scunthorpe site, we generate process gases as by-products of blast furnace ironmaking, basic oxygen steelmaking and coke production on site. The priority is to maximise the use of process gases as fuel for other combustion processes within the site, such as steel re-heating prior to hot rolling and steam raising. In this way, we can avoid the import of other fuels such as natural gas and propane.

Recycled content

British Steel has prioritised the use of external recycled content in our manufacturing processes. We use the methodology from the international standard ISO 14021 to measure and assess the recycled content of our steel products. Maximising recycled content decreases our scope 1 emissions. At present 25% to 30% is the maximum recycled content achievable through the BOS route.

In the table below we present our recycled content figures for 2020 and 2021:

  2020 2021
Pre-consumer recycled content 9.1% 13.6%
Post-consumer recycled content 16.0% 11.9%
Recycled content according to ISO 14021 25.2% 25.5%


Responsible sourcing

Our customers recognise the benefits of sustainable development, both in meeting government guidelines, and improving social and environmental performance.

British Steel is certified to a good rating for the Environmental and Sustainability Standard BES 6001 Responsible Sourcing of Products, meaning our customers can be confident they are working with a supplier who is committed to sustainability and that it is embedded into our company ethos.

Through this external validation, customers are able to benchmark our performance and demonstrate they are sourcing products from a responsible supplier. Designers and developers use our products in the knowledge that they can secure additional credits under sustainability schemes, such as BREEAM, LEED and CEEQUAL.

The certification covers our Teesside, Scunthorpe and Skinningrove sites, where we manufacture rail, sections, wire rod, special profiles and semi-finished products. 

Sustainable products: higher strength and durability

Our dedicated New Product Development and Research & Development teams tailor the properties of steel to offer sustainable solutions.

For example, our industry award-winning HP335 rail delivers energy-efficient transportation of people and goods. Extended in-service monitoring shows track life can be more than doubled while also reducing maintenance requirements. In addition to the safety, cost and environmental benefits, using HP335 means greater network availability, delivering increased and better service on rail networks. Our portfolio of rail products can ensure the appropriate grade is utilised in the correct application to optimise rail life and performance, hence supporting a lower carbon transport network.

Our customers strive to optimise the life of machinery, while making it safer, more cost-effective and more energy efficient. Innovations such as higher strength crane rail offer better durability in service with the potential to use lighter sections, reducing installation and transport costs.

High-strength steel cutting edges and track shoes also offer extended life and improved durability for the materials handling industry.

Local sourcing: reduced transport emissions

By working with us, our customers positively influence the carbon footprint of their supply chain.

Steel transported within the UK produces 50% less CO2 than steel sections sourced from the EU. Supply routes can offer total emissions of less than 10kg CO2 per tonne of steel in some cases – 4 times less than steel sourced from mainland Europe. The average distance UK manufactured steel sections are transported to our customers is less than 150km. 

Resource use and waste management

Integrated steelmaking requires large amounts of raw materials such as iron ore and coal. It’s vital that we continue to optimise our consumption of these raw materials by minimising waste and ensuring that our by-products meet tight quality control requirements so that they can be used in other industry sectors. As a result of continued improvements in material management, well over 90% of all residue material produced across the site is subject to internal recirculation or external recovery / recycling.

Our most significant by-product is blast furnace slag. This is a valuable raw material for the concrete and construction industry, where it is used as a clinker substitute, thus reducing mineral extraction and CO2 emissions further.

Steelmaking slag is used extensively in civil engineering and agricultural applications, and tar and benzole from our coke-making processes are used within the chemicals industry.

In addition, iron and steelmaking slags sequester atmospheric CO2 through natural processes. Even after the manufacturing process, our by-products can help to off-set CO2 emissions.

In line with British Steel’s objective to reduce waste to landfill, we’ve enacted a number of waste reduction strategies at our Scunthorpe site. Applying the waste hierarchy, we encourage re-use of materials such as scale and gas-cleaning residues within site processes.

A wide range of technologies such as oxide briquettes, hydro-cyclones, re-use of oily residues and de-watering facilities have been implemented to recover materials back into the process.

Transport impacts

The impacts associated with the transportation of our raw materials to our manufacturing sites, delivery of our products to customers, and business travel are relatively small when set against the footprint of our manufacturing operations.

Nevertheless, we have an environmental policy commitment to reduce the environmental impact of our operations and products through the adoption of sustainable practices. For this reason, we seek to measure our transport impacts and to progressively reduce them.

A series of strategies have been developed to deliver this objective, for example:

  • Enacting shift from road to rail. Optimise weight of load where this is not possible
  • Link outward journeys with return legs to minimise empty running rate
  • Improve the efficiency of the contracted and subcontracted haulage fleet 

Water use

At our Scunthorpe site we’re currently achieving best practice with regards to water consumption at an integrated steelworks and, as such, can be considered to be a steel industry benchmark in this area.

Consumption per tonne of steel manufactured is below that associated with the application of best available techniques (BAT) according to the EU’s BAT reference document for iron and steel.
