Switzerland Experts On How Noida Airport Used Climate-Friendly Cement, Noida Jewar airport

Why in news

Noida International Airport became the first large-scale civil engineering project to use low-carbon Limestone Calcined Clay Cement (LC3) to reduce construction emissions.

Background

LC3 technology was developed through a global partnership between Indian IITs and EPFL (Switzerland). It reduces CO2 emissions by approximately 40% compared to traditional Portland cement while maintaining equivalent performance and durability.

Facts for Prelims

• S&TLC3: Limestone Calcined Clay Cement is a low-carbon alternative to traditional Portland cement.
• FactLC3 technology reduces CO2 emissions by approximately 40% compared to conventional cement.
• BodyEPFL: École Polytechnique Fédérale de Lausanne is a Swiss research institution involved in LC3 development.
• PlaceNoida International Airport (Jewar) is the first large-scale project to adopt this technology in India.

For Mains

Q. Discuss how the adoption of low-carbon construction materials like LC3 can contribute to India's commitment to achieving Net Zero emissions by 2070.

Dimensions to cover in your answer

• Scalability constraints: Transitioning from pilot projects like Noida Airport to nationwide industrial adoption of LC3 standards.
