Our ambition is for low-embedded carbon steel production with a phased reduction of CO2 intensity by 2035 and 2050.
Our Low-Carbon Roadmap, which we launched on 7 October 2021, 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, we will use a range of techniques and innovations including:
Our 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.
*1 Baseline year 2020
Through the 2015 Paris Agreement, world governments committed to limiting global temperature rise to well below 2°C above pre-industrial levels and pursuing efforts to limit warming to 1.5°C. In 2018, the Intergovernmental Panel on Climate Change (IPCC) warned that global warming must not exceed 1.5°C above pre-industrial temperatures to avoid the catastrophic impacts of climate change. To achieve this, greenhouse gas (GHG) emissions must halve by 2030 – and reduce to net zero by 2050.
Many of our customers require us to have climate change targets and be working to reduce our CO2 intensity. The SteelZero initiative is a scheme that customers can sign up to in order for them to demonstrate their commitment to carbon reductions. SteelZero is an initiative by the Climate Action group who are an international non-profit group founded in 2003.
A SteelZero commitment by a steel user requires them to buy 50% of steel by 2030 that is low carbon as defined by SteelZero initiative.
SteelZero has minimum requirements as follows:
Internal analysis shows that the best path for us to meet one of these requirements is by adopting a science-based target.
It’s important to understand how CO2 emissions are characterised. Typically, we use the terms Scope 1, Scope 2 and Scope 3 emissions, these are explained below.
The distribution of our CO2 emissions is approximately as follows:
It is essential that we are focused on reducing its Scope 1 and 2 emissions that are under our direct control.
A wide range of emissions reporting scopes exist but there is, as yet, no harmonised and globally recognised definition of net-zero steel nor green steel. A number of organisations, including but not limited to World Economic Forum, Energy Transitions Commission, ResponsibleSteel™, Science Based Target initiative and the ACT (Assessing low-Carbon Transition®) Initiative, are currently working on the development of such a definition.
Based on the adoption and growth of SteelZero, it’s deemed to be the best approach to adopt a science-based target and review the target and scope framework as this area develops.
We’ve proposed and modelled CO2 reductions based on Scope 1 and Scope 2 emissions. This is for several reasons. Firstly, we must focus on the largest proportion of emissions so Scope 1 must be included. Secondly, we’d expect Scope 2 emissions to be a much greater percentage of the total with potential electrified steel making. Therefore, it is correct to include these now, and the model includes increases in Scope 2 emissions in the overall reduction plan. Thirdly, we expect the UK electricity grid to continue to decarbonise over the next 10-15 years therefore we need to be prepared to claim this benefit in later years. Lastly Scope 3 emissions are excluded as they are relatively small and our ability to fully influence emissions reduction in this category is deemed to be low, and Scope 3 is seen as a lower priority for emissions reduction.
We expect the assessment of steelmaking CO2 emissions globally to continue to be developed and in the medium term we might have a need to reassess using emerging methodologies to include Scope 3 emissions.
Low-embedded carbon steel is a term we will use to describe steel produced by British Steel that has significantly lower carbon intensity associated with its production than our steel has today. There is not a quantifiable figure that we recognise nor is there an international standard for low-embedded carbon or green steel.
A number of organisations, including but not limited to World Economic Forum, Energy Transitions Commission, ResponsibleSteel™, Science Based Targets initiative and the ACT Initiative, are currently working on the development of such a definition.
Net zero is a term used nationally and internationally to describe a position in 2050 where the net CO2 emissions are such to prevent temperature rises that drive the dangerous effects of climate change. At present, we’ve adopted the term net-zero steel as our adoption of a science-based target, which demonstrates a reduction pathway to support the steel sector’s contribution to a sustainable position by 2050.
We report our direct CO2 emissions for the Scunthorpe Works, Teesside Beam Mill and Skinningrove Special Profiles mills to the UK Regulator the Environment Agency and this data is independently verified by BSI Assurance UK Ltd. This data is based on the Greenhouse Gas Regulations and UK Emissions Trading Scheme scope (UK ETS).
In 2013 worldsteel developed a common methodology to measure CO2 emissions in steel plants – ISO 14404:2013 ‘Calculation method of carbon dioxide emission intensity from iron and steel production’. The scope of reporting includes the upstream manufacture of electricity, raw materials and fuels.
Externally we may in the future continue to use the worldsteel methodology for reporting CO2 emissions. The Low-Carbon Roadmap uses UK ETS Scope 1 data combined with Scope 2 data based on UK government annually published CO2 emission factors for electricity generation. We use data from the worldsteel methodology for Scope 3 emissions.
Through the adoption of the 2015 Paris Agreement, the UK government has set a target of net-zero carbon emissions by 2050 for the UK; note this is for the country and not specific sectors. The UK government has set in law an additional climate change target, cutting emissions by 78% by 2035 compared to 1990 levels to meet the overall target of Net Zero by 2050.
Globally 2030 is widely seen as a suitable interim target ahead of a net-zero target in 2050 and is used by SteelZero as the interim target deadline.
The Low-Carbon Roadmap is designed to deliver CO2 reduction by 2030, 2035 and 2050 to align to UK national, international and customer-driven reduction targets.
The Science Based Targets initiative (SBTi) drives ambitious climate action in the private sector by enabling companies to set science-based emissions reduction targets.
The SBTi is a partnership between CDP (https://www.cdp.net/), the United Nations Global Compact (www.unglobalcompact.org), World Resources Institute (WRI) (www.wri.org) and the World Wide Fund for Nature (WWF) (panda.org/climatebusiness).
Science-based targets provide a clearly defined pathway for companies to reduce carbon emissions, helping prevent the worst impacts of climate change and future-proof business growth.
Targets are considered ‘science-based’ if they are in line with what the latest climate science deems necessary to meet the goals of the Paris Agreement – limiting global warming to well below 2°C above pre-industrial levels and pursuing efforts to limit warming to 1.5°C.
