Agnes Chan is part of a stealth solar revolution bubbling up in the US. The retired teacher has a tiny solar system propped up in her backyard in Berkeley, California, and plugged into a regular outlet. It cost around $2,000, shaves about $50 off her monthly bills, and she's evangelical about it. "I have already recommended it many times," she said. Originally, Chan had wanted a full rooftop solar system, but the $20,000-plus price tag was unaffordable. Plug-in solar offered a cheaper, portable and more flexible option: It was incredibly easy to set up, would help keep her 100-year-old house toasty this winter and would pay for itself in three years. Chan is one of a growing number of Americans turning to plug-in solar — also called "balcony solar" as it's often slung over balconies — to help bring down soaring energy bills. Even as the Trump administration seeks to squash renewable energy, the interest is spurring action in nearly 30 states that are now considering legislation to make these cheap, small systems more accessible. There are hurdles, however. Plug-in solar currently exists in a legal "gray area," said Cora Stryker, co-founder of Bright Saver, a non-profit that advocates for balcony solar. Almost every state requires an agreement with the local utility company, a process that can take months and add costs. That's why people are going stealth and hooking up "guerilla solar" systems without telling their utility, Stryker said. Read more at the link in our bio. 📸: KT Kanazawich/AP; David J.

Sustainable construction is accelerating towards measurable decarbonisation as innovation, policy, and supply chain governance begin to align. In London, bio‑based wallboards such as Adaptavate’s Breathaboard—used in Legal & General’s new headquarters—demonstrate how low embodied carbon materials with environmental product declarations (EPDs) are entering large‑scale deployment. This marks a shift from theory to delivery in eco‑friendly construction and underscores the importance of Whole Life Carbon Assessment across sustainable building design.

UK policy now links agriculture and the built environment through a £240 million expansion of the Sustainable Farming Incentive, improving soil health and cutting reliance on high‑carbon fertilisers. These measures support decarbonising the built environment and address the embodied carbon in materials central to net zero Whole Life Carbon targets. As scrutiny of the Greenhouse Gas Protocol exposes inconsistencies in corporate carbon reporting, reliable lifecycle assessment frameworks are becoming critical to verifying low carbon building outcomes and aligning procurement with sustainable material specification.

Growth in renewables, driven by projections of a fourfold expansion in offshore wind capacity by 2035, is reshaping operational emissions and strengthening the foundation for carbon neutral construction and energy‑efficient buildings designed under BREEAM V7 guidelines. This integration of renewable building materials and design principles reflects a more mature phase in the industry’s evolution towards net zero carbon buildings and a functioning Circular Economy in construction.

The sector’s trajectory points towards verified performance, where Whole Life Carbon, Life Cycle Cost, and transparent building lifecycle performance replace aspirations with measurable delivery. The transition from demonstration to large‑scale adaptation defines modern environmental sustainability in construction, confirming that the next decade will test implementation rather than intent across every level of sustainable building practices and green construction worldwide.
