Current roadmaps for decarbonising the steel industry, while aiming for near-zero emissions by 2050, are projected to miss net-zero targets by approximately 10% due to significant barriers in resource availability, technological investment, and policy. This resource management research insight is drawn from a 2025 study published in Environmental Impact Assessment Review. Using Critical literature review, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Designers and engineers need to proactively address resource constraints and broader sustainability impacts in their material selection and manufacturing process design, moving beyond a sole focus on CO2 reduction.

Key Findings
- 01Current roadmaps project near-zero emissions by 2050, but fall short of net-zero targets by ~10%.
- 02Key barriers include: availability of recycled scrap and high-grade iron ore, de-risking technology investment, uncertain demand and cost gaps, availability/affordability/reliability of renewable energy and hydrogen, skilled workforce shortages, weak policy signals, and lack of fair competition regulation.
- 03Significant sustainability gaps exist, with limited discussion of social and environmental impacts beyond CO2 mitigation, particularly concerning raw material extraction, transport, use, and end-of-life stages.
- 04Strategic international collaboration and shared responsibility are integral for a just sustainability transition.
Application
Design takeaway
Designers and engineers need to proactively address resource constraints and broader sustainability impacts in their material selection and manufacturing process design, moving beyond a sole focus on CO2 reduction.
How to apply
When selecting materials for a design project, research not only their embodied carbon but also the availability and sustainability of their raw material sources, and consider end-of-life scenarios that minimise resource depletion.
Project actions
- 01When choosing materials, think about where they come from and what happens to them afterwards, not just how they're made.
- 02Consider how your design can use less material or materials that are easier to recycle or reuse.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Comprehensive review of existing literature and roadmaps.
- +Identifies critical, often overlooked, sustainability gaps beyond CO2.
Limitations
The roadmaps analysed are projections and may not reflect future realities. The study focuses on CO2, and other environmental impacts might be equally or more significant.
Reliability & validity
The reliability of the findings depends on the quality and consistency of the roadmaps analysed. Validity is strengthened by the critical review approach, which aims to identify consensus and gaps.
Think critically
Given the identified limitations in current steel decarbonisation roadmaps, what alternative or complementary strategies could designers and engineers explore to achieve truly net-zero outcomes in material-intensive product design?
Design Principles
"Prioritise lifecycle resource stewardship and holistic sustainability in material and process design."
This insight is crucial for designers and engineers involved in product development and manufacturing. It highlights that the fundamental materials and energy sources required for a sustainable future are not yet readily available or de-risked, necessitating innovative solutions for resource efficiency and alternative material sourcing.
What This Means for Your Design
Making steel without polluting is hard! Current plans are good but won't get us to zero pollution because we don't have enough recycled metal, clean energy, or clear rules. We also need to think more about the impact of mining the raw materials.

Paragraph starter
The decarbonisation of heavy industries like steel production faces significant challenges, with current roadmaps projected to fall short of net-zero targets due to critical resource limitations, technological investment risks, and policy uncertainties. As highlighted by Rumsa et al. (2025), a near-zero emissions goal by 2050 is achievable, but achieving true net-zero requires addressing not only CO2 mitigation but also the broader social and environmental impacts of raw material extraction, transport, use, and end-of-life stages, alongside ensuring the availability of renewable energy and hydrogen.
