In an unassuming industrial park 30 miles outside Boston, engineers are building a futuristic machine to replicate the energy of the stars. If all goes to plan, it could be the key to producing virtually unlimited, clean electricity in the United States in about a decade.
The donut-shaped machine Commonwealth Fusion Systems is assembling to generate this energy is simultaneously the hottest and coldest place in the entire solar system, according to the scientists who are building it.
It is inside that extreme environment in the so-called tokamak that they smash atoms together in 100-million-degree plasma. The nuclear fusion reaction is surrounded by a magnetic field more than 400,000 times more powerful than the Earth's and chilled with cryogenic gases close to absolute zero.
The fusion reaction — forcing two atoms to merge — is what creates the energy of the sun. It is the exact opposite of what the world knows now as "nuclear power" — a fission reaction that splits atoms.
Nuclear fusion has far greater energy potential, with none of the safety concerns around radioactive waste.

A tightening regulatory and technical landscape is redefining sustainable construction across the UK and beyond. The Building Safety Act is reshaping project governance by requiring transparent reporting and accountability that link safety with environmental sustainability in construction. Compliance processes are driving a shift toward whole life carbon assessment, embedding sustainable building design principles at the earliest design stage and quantifying both operational and embodied carbon.
Digital systems such as the government’s waste‑tracking initiative are enabling circular economy in construction practices, mandating traceable material flows and revealing the carbon footprint of construction through verified lifecycle assessment. These data‑driven mechanisms enhance resource efficiency in construction and reinforce the wider transition to low embodied carbon materials and eco‑friendly construction.
Investment is converging on decarbonisation at scale. A new £120 million waste‑to‑hydrogen facility is designed to transform residual waste into clean fuel, supporting low carbon design and resilient net zero carbon buildings. Growth in grid‑balancing storage improves the stability of renewable‑powered operations, a prerequisite for energy‑efficient buildings and low carbon building performance across portfolios.
Governance frameworks are also advancing. The creation of a dedicated leadership structure for the Greenhouse Gas Protocol elevates global consistency in measuring whole life carbon and encourages transparent benchmarking using environmental product declarations (EPDs). This maturity strengthens sustainable building practices, fosters green construction aligned with BREEAM v7 standards, and supports decarbonising the built environment through life cycle cost and performance management.
The cumulative effect signals a transition to net zero whole life carbon imperatives governed by robust data, certified materials, and measurable outcomes. The progress may appear administrative, yet it represents the essential infrastructure of sustainable material specification, circular construction strategies, and long‑term green infrastructure supporting a truly carbon neutral construction sector.
