Sandbag has submitted a response to the European Commission’s call for evidence on the Industrial Decarbonisation Accelerator Act (IDAA).
Our response sets out four principles to guide the development of credible green steel labels that support truly low-carbon production and avoid greenwashing.
To be effective, labelling must reflect full-system emissions and environmental impacts — not just reductions at plant level.
About the response
Sandbag’s response addresses concerns that emerging steel labelling schemes often rely on narrow or inconsistent metrics, risking poor alignment with EU climate goals. It recommends a set of common principles to ensure future steel labels drive real decarbonisation and can be used reliably in EU funding, procurement, and regulatory frameworks.
Key findings
Sandbag proposes four core principles for future EU steel labelling systems:
- Exclude fossil-based production routes
Steelmaking routes that rely on fossil fuels, carbon capture and storage (CCS/CCU), or fossil-based electricity should not qualify for the top tiers of any label.
- Support dynamic phase-out of high-emission classes
Labelling frameworks should progressively exclude the worst-performing routes, while incentivising the adoption of cleaner processes and inputs.
- Use forward-looking emissions criteria across full system boundaries
Categories should be based on lifecycle emissions and best available technologies — not historical EU ETS benchmarks — and include upstream impacts like methane leakage, as well as induced emissions from electricity use, which can vary depending on timing and location.
- Reward energy and feedstock efficiency
Labels should favour routes with lower energy input, direct electrification, scrap use, or hydrogen — with proper accounting for efficiency losses and imports.

Chemicals and CCS/U: Exploring the role of carbon capture in the sector’s transition to ‘circularity’
This technical brief explores the potential role of carbon capture, storage and utilisation (CCS/U) for Europe's chemicals sector.
We find that CCS/U will be necessary in Europe’s chemicals sector, but only to a limited extent in targeted applications.
Steel labelling: Beyond the sliding scale
As EU policymakers debate how to certify low-carbon steel, Sandbag’s new briefing analyses the “sliding scale” method — and outlines why it may hinder rather than help decarbonisation. A new model is proposed based on product-specific benchmarks, multi-tier ratings, and circularity incentives.
Scrap Steel at Sea: How ship recycling can help decarbonise European steel production
As Europe seeks to decarbonise its steel industry, a new Sandbag report highlights an overlooked solution: high-quality scrap steel from retired ships. With up to 15 million tonnes of certified scrap available annually, ship recycling could meet 20% of EU steel scrap demand — if policy gaps are addressed.
Sandbag’s feedback to the call for evidence on the Circular Economy Act
Sandbag welcomes the Circular Economy Act (CEA) as an important step to accelerate the transition to a circular economy in the EU. Progress in this area has been slow and this act is sorely needed to address systemic issues holding back circularity, including the current fragmented approaches across Member States.
Electrification or electrical decarbonisation? We need both!
We agree with the European Commission’s general diagnosis that increasing the share of electricity in overall energy consumption is necessary to achieve deep decarbonisation. However, it is not sufficient. If overall energy use increases, or if electricity generation does not decarbonise rapidly, then electrification may fail its decarbonisation role.
Heat up industry, not the climate!
The European Commission has set out proposed terms and conditions for its auction on electrified /renewable industrial heat under the Innovation Fund (IF). We support the IF’s acknowledgment that indirect emissions are linked to the timing of electricity consumption rather than the source of electricity used. However, although it claims an intention to limit electricity use at hours of high marginal emission intensity, we are concerned that the proposed terms might lead to the opposite and significantly limit the scheme’s climate benefits.
Extending the CBAM to indirect emissions
The European Commission is considering amending the Carbon Border Adjustment Mechanism (CBAM) to include indirect emissions of CO2 from the use of electricity in the manufacturing of CBAM-covered goods.
Getting Electrification Right: The broader challenge of induced emissions
This report examines how the climate impact of electricity use is shaped not just by its source, but also by its timing and location. It evaluates the EU’s RED III framework and associated hydrogen targets, using the RFNBO standard as a case study. The analysis shows that ill-timed use of renewable electricity (particularly for hydrogen production) can inadvertently drive fossil generation. It argues for more strategic use of electricity to avoid these unintended consequences and support genuine decarbonisation.
