The Panama Canal is an extraordinary feat of engineering. This waterway, which slices 50 miles across the isthmus of Panama to connect the Atlantic and Pacific Oceans, is an artery of world trade and a key source of Panamanian pride. But it’s in trouble. Historically, major dry events happened in Panama around once every 20 years, said Steve Paton, who heads the physical monitoring program for the Smithsonian Tropical Research Institute in Panama. But the country has experienced three in less than three decades. In 2023 and 2024, an El-Niño-fueled drought pushed Lake Gatún, which forms a major part of the canal, to critical lows. Canal authorities were forced to reduce the transits from a typical 36 a day to 24, disrupting global supply chains. The canal authority has landed on a plan to dam the nearby Río Indio to create a new reservoir. The $1.6 billion project will take an estimated six years to complete. The project is controversial, however, as it means flooding communities, displacing around 2,300 people and submerging homes, farms, schools and healthcare clinics. And now, the Panama Canal finds itself in the crosshairs of President Donald Trump’s expansionist agenda. “We were already in a situation of instability … then President Trump jumps onto the scene,” said Osvaldo Jordán, a political scientist based in Panama City.

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.
