Innovative technologies in environmental sustainability in construction are gaining global attention. April 2025 introduced new methods, including the use of red onion dye to extend the lifespan of solar panels, which supports lower life cycle cost and reduces waste in renewable energy for the built environment. Sector leaders are also advancing carbon capture technology. The Svante and Mercer International partnership aims to cut operational carbon through a carbon capture and storage project at an Alberta pulp mill, highlighting industry-wide commitment to reducing the carbon footprint of construction.
Material innovation remains central to sustainable construction. Research now demonstrates that using zinc as a construction material in a single home can prevent over 50 tonnes of embodied carbon emissions. If 10% of new North American homes utilised zinc, whole life carbon savings would be significant. Focus on low carbon construction materials and low carbon design underlines the importance of reducing embodied carbon in materials to achieve global goals for net zero whole life carbon and building lifecycle performance.
Supply chain traceability is growing in importance amid tightening regulatory requirements. The IMPACTT project has published new guidance addressing traceability and compliance for timber used in buildings. Results support sustainable material specification and responsible sourcing in anticipation of the EU Deforestation Regulation, invigorating eco-design for buildings by ensuring green building materials meet both lifecycle assessment and environmental product declarations (EPDs) standards.
Circular economy in construction practices are expanding. The extension of a successful carpet recycling takeback scheme demonstrates resource efficiency in construction and the practical application of circular construction strategies. Such initiatives support end-of-life reuse in construction, promote sustainable building practices, and reduce landfill waste—vital steps for realising eco-friendly construction and a fully circular economy model across the sector.
Investment in climate solutions is accelerating. Programmes such as Amazon’s sustainability accelerator provide funding and mentorship to climate-focused start-ups, supporting green construction innovation and expediting market readiness for net zero carbon buildings, sustainable architecture, and carbon neutral construction methods. These efforts help to decarbonise the built environment and foster sustainable urban development globally.
Taken together, these industry advances reflect clear progress toward whole life carbon assessment, carbon footprint reduction, and sustainable building design. Ongoing collaboration, advanced materials, circular economy initiatives, and transparent sourcing are helping to reshape sustainable construction. This is essential for achieving net zero carbon, low-impact construction, and resilient, energy-efficient buildings worldwide.
