Noida Airport to Use Low-Carbon LC3 Cement, India’s First Infra Project of Its Kind

Noida International Airport (NIA) is set to become the first major infrastructure project in India to incorporate low-carbon LC3 (limestone calcined clay cement) in its construction.

The airport is slated to start operations on 30 October 2025, with commercial flights expected from December.

As part of its sustainable design ambition, NIA is adopting LC3 cement, which can reduce CO₂ emissions by up to 40 per cent compared to traditional Portland cement, reported The Times of India. The move is being hailed as a benchmark in green construction practices.

Officials involved with the project said that several structural components, including service structures, terminal flooring and non-loadbearing walls, will use the LC3 formulation.

The shift follows technical collaboration with material scientists and cement manufacturers, ensuring the new cement mix meets durability and strength criteria under Indian conditions.

Construction sources confirmed that integrating LC3 into the ongoing build required adjustment of mix proportions and quality assurance protocols. However, early trials aligned with performance expectations, allowing broader adoption across NIA’s civil works.

The adoption of LC3 at such scale in airport infrastructure is expected to set a precedent for sustainable building in India. Construction experts and urban planners are watching closely, with hopes that future projects, roads, metro stations, buildings, may follow this low-carbon pathway.
