Colin Goodson knows more about energy than most people. The tall, bearded Mainer is an engineer on an offshore oil drilling ship in the Gulf of Mexico. But when it came time for him to build a home in Southern Maine, Goodson largely bypassed fossil fuels. The house he built is entirely off the grid, powered from rooftop solar and batteries that convert the sun’s energy to electricity. Electrons power much of his two-story home; it is heated and cooled with heat pumps, and Goodson and his wife cook meals on an induction range. Incredibly well-insulated, the entire home is heated by a small wood stove. Despite also having initial concerns about her husband’s off-the-grid aspirations, Katie Goodson is a convert as well – especially after the lights stayed on during an intense storm that knocked their neighbors’ electricity out. “I would never go back,” she told CNN. “When I tell co-workers or neighbors that we live off-grid and they see the house, they’re always like, ‘Whoa, this isn’t what I was expecting!’ It’s really fun surprising people; I live a totally normal life.” The Goodsons are part of a small but growing number of homeowners who are choosing to build energy-efficient “panelized” homes that are pre-made in a factory. The homes are better for the climate, and although they have a high upfront cost, several homeowners say their energy savings, quality of life and overall cost of living has greatly improved since moving in.

The University of Derby has launched the UK’s first Institute of Carbonomics to pioneer research around carbon quantification and reduction, with strong industry backing. This initiative aims to improve accuracy in Whole Life Carbon Assessment, offering construction firms a more precise route to tackling Whole Life Carbon in materials and processes. By integrating carbon metrics into decision-making, the institute could transform how sustainable building design is delivered and support the shift towards net zero Whole Life Carbon strategies.

Clean energy investment is gaining momentum as Gresham House expands its portfolio through the acquisition of SUSI Partners, lifting assets under management to over £10 billion. This injection of capital into renewable infrastructure and green construction signals a positive outlook for sustainable building practices. As investors look to align with environmental Climate Change sustainability in construction, the financial market is playing a key role in scaling up energy-efficient buildings and low carbon construction materials.

The London Stock Exchange has highlighted a reduction in the carbon intensity of portfolios; yet overall emissions across real estate and infrastructure remain high. This underlines the gap between ambition and measurable impact within the built environment. Greater adoption of lifecycle assessment and Whole Life Carbon methodologies is required to close this gap, ensuring that Life Cycle Cost and carbon footprint reduction are integrated into mainstream investment and design strategies.

The shift to hydrogen at the UK’s Bacton gas terminal illustrates how existing infrastructure and skills can be repurposed for the clean transition. For construction, this demonstrates the importance of resource efficiency in construction, the potential of Circular Economy in construction approaches, and the upskilling of the workforce to deliver net zero carbon buildings. Embedding eco-design for buildings alongside low carbon design practices will be central to this transformation.

Broader developments such as the ratification of the global oceans treaty reinforce the urgency of protecting biodiversity and ecosystems. Though not directly tied to sustainable construction, these frameworks influence shoreline planning and climate resilience strategies. Sustainable urban development and green infrastructure increasingly require life cycle thinking in construction to balance resilience, functionality, and environmental impact of construction activities.

Climate pressures continue to escalate, with extreme weather and rising temperatures reinforcing the urgency for carbon neutral construction pathways. From decarbonising the built environment to advancing circular construction strategies and sustainable material specification, the sector must keep accelerating change. Net zero carbon now depends not only on technical innovation but also on embedding sustainable design principles and green building materials into every aspect of building lifecycle performance.
