India has launched a major initiative to decarbonise the steel sector with a shift towards hydrogen-based direct reduced iron production. This development could lower the embodied carbon in steel, setting a precedent for low carbon construction materials in both the Indian and global markets. Reducing embodied carbon in materials is central to achieving net zero whole life carbon targets for new builds, impacting the carbon footprint of construction worldwide.
Artificial intelligence is rapidly advancing environmental sustainability in construction. Integrating AI into sustainable building design and construction practices can result in up to 26% operational carbon reductions according to recent industry reports. Digitalisation and smart technologies are emerging as essential tools for life cycle cost management, lifecycle assessment, and enhancing building lifecycle performance, pointing towards a future of energy-efficient, low carbon buildings.
The construction equipment sector is increasing resource efficiency in construction with smart technologies. Komatsu Europe's expansion of its 3D Machine Guidance system compatibility improves eco-design for buildings and infrastructure, supporting efficient earthmoving and reducing waste. Such innovations contribute to circular construction strategies and help minimise the environmental impact of construction sites.
UK waste management continues to support the circular economy in construction, with new certification schemes for compostable materials backed by major companies. These schemes enhance sustainable material specification and end-of-life reuse in construction while addressing challenges related to disposal of packaging and site consumables. Promoting a circular economy supports low-impact construction and the reduction of construction waste, vital for green construction and sustainable building practices.
British Steel’s stable supply of raw materials to its Scunthorpe blast furnaces and retention of thousands of jobs secures the supply chain for recycled and renewable building materials. Reliable sources are crucial to sustainable construction and achieving whole life carbon reductions, especially as industry pressures to decarbonise and transition to net zero carbon buildings intensify.
A new e-waste Fixing Factory in Hackney aims to drive resource efficiency and circular economy outcomes by extending the life of electrical equipment used in construction. Repair and reuse of electronic tools lessen the environmental impact of construction, reduce embodied carbon in materials, and align with life cycle thinking in construction, supporting the transition to sustainable urban development and carbon neutral construction.
