Aldar And EMSTEEL Join Forces To Build Abu Dhabi’s First Net Zero Carbon Mosque Using Hydrogen-Based Steel

Aldar is set to become the first developer in the Middle East and North Africa to use hydrogen-based steel rebar in a construction project. This initiative, supplied by EMSTEEL Group, will significantly cut carbon emissions during the building of Abu Dhabi’s first net zero carbon mosque in Sustainable City Yas Island. The mosque aims for LEED Zero Carbon certification, focusing on clean energy and low-carbon materials.

The collaboration between Aldar and EMSTEEL marks a significant step towards sustainable construction. It aims to boost demand for eco-friendly materials in the region, aligning with the UAE's National In-Country Value (ICV) programme. This partnership is expected to circulate economic benefits within the UAE while promoting innovation in the construction sector.

Hydrogen-based steel production can reduce carbon emissions by up to 95% compared to traditional methods. Steel is a major contributor to embodied carbon, second only to concrete, accounting for up to 20% of a building’s total emissions. The adoption of this technology represents a substantial advancement in reducing the environmental impact of construction projects.

The partnership was officially launched at Make It In The Emirates 2025, an event focused on the UAE's growing industrial sectors. Key figures present included Talal Al Dhiyebi, Aldar's Group CEO, and Eng. Saeed Ghumran Al Remeithi, EMSTEEL's Group CEO. Their presence underscored the importance of this initiative for both companies and the wider industry.

Salwa Al Maflahi from Aldar highlighted that using low-emissions hydrogen-based rebar is transformative for their industry. "The low emissions hydrogen-based rebar is more than a material innovation—it’s a catalyst for reshaping our industry," she stated. This move supports Aldar's goal of decarbonising its supply chain and achieving net zero ambitions.

Michael Rion from Emirates Steel expressed pride in supporting sustainable construction through this project. "At EMSTEEL, we are proud to support the region’s transition to sustainable construction by supplying low-emissions hydrogen-based rebar for this landmark project," he said. This collaboration signifies progress in using green steel and aligns with the UAE’s sustainability goals.

Aldar's Broader Sustainability Strategy

Aldar has pledged to reach net zero carbon emissions by 2050 through various initiatives such as sustainable design and green construction practices. The company is also increasing LEED certifications across its properties and enhancing circular economy practices by recycling construction waste extensively.

This project sets an example for future developments as Aldar and EMSTEEL explore wider adoption of green steel across different infrastructure projects in the UAE and beyond. Their efforts aim to decarbonise the value chain within the construction industry, driving long-term positive impacts on the built environment.
