Green Steel and Decarbonization Future of Steel Buildings and Supplies | DigECA

While the world heads to net-zero, its status as a sector responsible for over 7% of global CO₂ emissions ensures that the Steel industry is in the spotlight, and steel consumes a lot of resources, which is why it is obliged to start taking measures for the world to be able to achieve climate objectives. This is where green steel comes in.

But what is green steel, and does it have the potential to supplant traditional steel in the market? The floating island is through a colonnade of solar tubes. More importantly, will decarbonized steel be the new normal to build with in construction, real estate, infrastructure, manufacturing, and everywhere else?

Read here to explore the rise of green steel production, as well as its opportunities, challenges, and how platforms such as DigECA by Tata Steel are helping to drive this vital transformation.

Green steel is steel produced without carbon emissions. Green steel, by contrast, is produced using a variety of methods through the following process:

• DRI Process Hydrogen is an integral part of the direct fines-to-DRI process.
• Electric Arc Furnaces (EAF) are powered by renewable energy.
• There are things called carbon capture and storage (CCS).

This change in technique is the basis of steel industry decarbonization.

According to the World Steel Association, transitioning to decarbonized steel could reduce emissions by up to 90% per ton of steel, particularly when powered by renewable energy and green hydrogen.

Decarbonized steel could reduce emissions by 30 to 90 percent per ton of fabricated steel, particularly if it were powered by renewable energy and green hydrogen, according to the World Steel Association.

The need for green steel feedstocks is rapidly accelerating as global ESG (Environmental, Social & Governance) objectives, legislation, and consumer demand continue to increase. Workers in the automotive, construction,  and renewable energy sectors are searching for greener steel.

Eco-friendly urban developments are already giving precedence to green steel buildings.

Automotive giants such as Volvo and Mercedes-Benz have pledged to use steel from green products in their production.

The European Union is implementing carbon border adjustment measures to compel both to increase the share of steel decarbonization to stay in the game.

Needless to say, these problems that we must solve along the way. Green steel production is  currently 20-30% more expensive than conventional processes. The hydrogen and renewable energy industries are booming, but it remains difficult to follow which products are “green” due to conflicting guidelines.

But the market is recalibrating. As carbon-pricing goes wider and customers want sustainability down the value chain, the cost of not decarbonizing could far exceed the investment in green steel.

As industries look for viable and cost-effective green substitutes, a platform like DigECA by Tata Steel is a reliable digital procurement partner for decarbonization.

DigECA (Digital E-Commerce for Carbon Abatement) is an innovative platform that seeks to simplify green steel procurement and allow buyers to make informed, environmentally-conscious choices.

 

Here’s what separates DigECA from its asynchronous counterparts:

• Verified green steel sourcing: Choose from a curated selection of decarbonized steel products from Tata Steel and its partners.
• Carbon impact metrics: Evaluate and compare products based on their carbon footprint before purchasing.
• Sustainability-focused filters: Find products suitable for green steel buildings, low-emission projects, and more.

 

“With DigECA, we are enabling a marketplace for sustainability. It’s not just about selling steel—it’s about selling a better future,” says a spokesperson from Tata Steel’s Digital & Innovation team.

Whether you're an architect building a LEED-certified structure or an OEM aiming for a carbon-neutral supply chain, DigECA gives you the tools to choose smart and build sustainably.

The answer is trending toward yes. By 2030, BloombergNEF estimates that green steel could make up 10–15% of the global steel market, with the potential to accelerate if policy incentives, carbon pricing, and innovation align.

With governments, industries, and consumers rallying behind the idea of a low-carbon future, decarbonization in steel is no longer optional—it’s inevitable.

The leaders of tomorrow won’t just be the biggest—they’ll be the greenest.
