IIGCC sets out investor priorities for the next government to help accelerate transition to a competitive, energy-secure, resilient, and climate-neutral economy
Sustainable construction is moving from carbon ambition to engineered resilience, with water, heat and power shaping the next phase of environmental sustainability in construction. Britain’s sustainable drainage systems debate shows why whole life carbon, life cycle cost and building lifecycle performance must be assessed together. Flexible SuDS funding is now central to sustainable urban development, allowing new developments to retain water during wet winters, support green infrastructure and improve climate resilience during dry summers.
Infrastructure owners are widening their sustainability programmes beyond emissions alone. Transport for London’s updated environmental plan, with more than 70 actions on air quality, climate adaptation and decarbonisation, reflects a stronger focus on lifecycle assessment, resource efficiency in construction and carbon footprint reduction across major assets. The proposed £1bn battery-electric train fleet for the Pennines reinforces the commercial value of low carbon design, net zero carbon delivery and green construction linked to manufacturing, infrastructure upgrades and long-term operational efficiency.
Rising digital infrastructure demand is exposing a critical weakness in claims around eco-friendly construction. Reports of nitrogen oxide emissions from gas turbines serving a major AI data centre, coupled with warnings over Europe’s AI cooling challenge, highlight the environmental impact of construction when power and cooling strategies are treated separately from whole life carbon assessment. Data centres pursuing net zero carbon buildings need energy-efficient buildings, low-impact construction, renewable power and credible lifecycle assessment, not temporary fossil generation and water-intensive cooling.
Offsite manufacturing remains a major route to sustainable building practices, lower waste and tighter quality control, but the sector’s message is clear: the gains depend on early decisions in sustainable building design, eco-design for buildings and sustainable material specification. Embodied carbon, embodied carbon in materials and the carbon footprint of construction must be addressed before procurement, supported by low carbon construction materials, green building materials, renewable building materials and environmental product declarations (EPDs).
Weakening UK construction output leaves little tolerance for late redesign, inefficient procurement or superficial carbon neutral construction claims. The direction is clear: net zero whole life carbon, circular economy in construction, circular construction strategies and end-of-life reuse in construction are becoming practical requirements, not branding exercises. BREEAM, BREEAM v7 and stronger life cycle thinking in construction will increasingly shape low carbon building decisions, net zero carbon targets and the wider task of decarbonising the built environment.
