Not long ago, reducing greenhouse gas emissions was largely a voluntary commitment for the global steel industry. Companies set targets, announced investments, and made sustainability commitments aligned with their business priorities and timelines.

That era is ending.

Today, emissions affect whether a steel producer can compete, where it can sell, and whether it can meet its customers’ expectations. Trade rules are incorporating carbon intensity. Buyers are looking deeper into their supply chains. Investors expect climate claims backed by credible data and transition plans.

In other words, the decision to decarbonise is shifting from voluntary to “volun-told.”

That shift is important. But it carries a risk: assuming that because the destination is shared, the pathway must be as well.

There is already evidence that a different approach delivers. Since the implementation of the Steel Climate Standard in 2023, nine independently certified Global Steel Climate Council member producers avoided more than 32.5 million tonnes of CO₂e emissions through 2025. That is roughly the annual emissions of 6.9 million ICE cars off the road for a year.

They did not achieve those reductions by following a single technology prescription. Producers incorporated more renewable energy, improved production efficiency, and increased scrap use. Each pursued strategies suited to their individual facilities and operating environments.

What they shared was not a production route. It was a common emissions trajectory and a requirement to measure and independently verify performance.

That experience points to a broader lesson for the global steel industry: set a common expectation for emissions performance, but do not dictate a common pathway to achieve it.

Different Roads to Net Zero

The scale of the challenge is enormous. The global steel industry accounts for roughly 4.1 billion tonnes of CO₂e emissions annually. But there is no single way to make steel, and no single pathway for lowering its emissions.

Consider the very different starting points of the world’s largest steel-producing markets.

• China, the world’s largest producer, still relies heavily on coal-based blast furnaces and faces the enormous task of transitioning a massive existing asset base.
• India is rapidly adding capacity to meet growing infrastructure needs, with less scrap available and many lower-emission technologies still costly or developing.
• The United States benefits from abundant scrap, significant electric arc furnace capacity, and a diverse energy base.

Even producers within the same country differ: facility age, customer requirements, and access to capital, scrap and raw material availability, electricity supply, infrastructure all shape which reductions are technically and economically feasible.

Those differences do not justify inaction. They make it more important to measure outcomes than to prescribe the route.

Some solutions, such as low-emission electricity, energy efficiency and increased scrap use, can deliver reductions today. Others, including direct reduced iron (DRI), hydrogen-based production and the replacement of major assets, will require substantial investment and technological advancement before they operate economically at scale.

What matters is whether they produce real, measurable emissions reductions.

Today, this is possible. Producers with different facilities, energy sources, raw-material constraints, and investment strategies avoided 32.5 million tonnes of emissions. These companies did not share a production route, but a common emissions trajectory and a standard to measure, verify and be transparent about their performance.

That is an important distinction: a technology-neutral approach does not lower the bar for decarbonisation. It sets the bar on emissions performance rather than prescribing how a company must reach it.

Carbon Is Becoming a Competitive Metric

This distinction matters more as carbon enters commercial decision-making.

The EU CBAM is the clearest example. Carbon intensity is no longer just information in a sustainability report; for steel entering the EU market, embedded emissions can translate into a financial obligation. Buyers in the automotive, construction, and infrastructure sectors are under pressure to address emissions throughout their value chains.

In this environment, simply calling steel “green” will not be enough.

Producers need credible emissions data. Buyers need to know what they are purchasing. Policymakers need methodologies that compare actual emissions performance without assuming a particular production technology is inherently good or bad.

And the industry needs independent verification that can distinguish measurable progress from marketing claims.

The goal should not be to crown one technology the answer to steel decarbonisation, or to reward producers for adopting a preferred process without examining the emissions it actually produces. The global steel sector should compete on demonstrated emissions performance.

That approach acknowledges the realities of a global industry while maintaining the urgency of the climate objective. A producer starting with higher emissions intensity should have a credible pathway to reduce it. A producer that has already invested in lower-emission production should receive recognition for that performance. Both should be expected to keep improving.

The next phase of steel decarbonisation will be harder than the last. Companies will confront different energy systems, policy environments, access to capital, and starting points.

Those differences are real. The expectation of progress should be equally real.

Steelmakers do not need to travel the same road to net zero. But increasingly, they will need to prove they are moving in the same direction.
