Study shows that steel corrosion is a major CO₂ threat
Steelpaint, a corrosion specialist based in Germany, has warned the industry that inadequate corrosion protection contributes more to global CO₂ emissions than the aviation sector.
Managing director Klaus Müller underlined the fact that premature steel failure leads to frequent replacements, increasing emissions from extraction, production and transport. A 2022 study found that 25% of global steel production is lost to corrosion, accounting for 4–9% of total emissions.
With 1.8 billion t of steel consumed in 2024 and demand rising, the issue is pressing. Steelpaint’s Dmitry Gromilin highlighted the role of advanced coatings in extending steel lifespan. The company’s Stelcatec coating, a low-VOC, isocyanate-free polyurethane, enhances steel preservation, reducing emissions at the source. Steelpaint called for greater industry focus on corrosion protection to support decarbonisation goals. (ah)
