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.

Ocean governance reforms now carry direct consequences for sustainable construction and environmental sustainability in construction. The UN High Seas Treaty and proposed protections for the Antarctic Peninsula introduce stricter environmental impact assessments for offshore and coastal developments, signalling an era of detailed whole life carbon assessment in marine-related infrastructure. Developers of subsea cables, interconnectors, and CO₂ pipelines will contend with extended consenting processes and biodiversity restrictions that influence material selection, eco-friendly construction practices, and low carbon design decisions across multiple jurisdictions. The evolution of marine spatial planning aligns with circular economy in construction principles, recognising supply-chain carbon exposure as both a design and compliance issue.
Trade policy disruption poses further challenges to sustainable building design. Prospective tariffs on low-carbon materials—such as green building materials, steel, engineered timber, and heat-pump components—threaten project timelines and budgets. Anticipated responses include regional procurement strategies, adoption of sustainable material specification, and more rigorous evaluation of embodied carbon in materials and life cycle cost performance. Demands for verifiable environmental product declarations (EPDs) and building lifecycle performance metrics are expected to rise as clients seek transparency for carbon neutral construction targets.
Climate volatility is reshaping low-impact construction strategies, particularly in flood-prone and mountainous regions. Designers must adopt adaptive lifecycle assessment frameworks that prioritise redundancy, attenuation, and slope stability. These approaches support net zero whole life carbon goals and reduce the carbon footprint of construction, reinforcing resilience and resource efficiency in construction.
The policy debate on decarbonisation is shifting toward measurable outcomes. Governments are preparing performance-linked procurement and finance mechanisms that embed whole life carbon benchmarks into material supply chains. The accelerating move toward net zero carbon buildings, green construction, and BREEAM V7 standards signals the transition from intent to implementation. Markets for low embodied carbon materials and circular construction strategies are scaling at pace, defining a new baseline for sustainable building practices and comprehensive whole life carbon accountability across the global built environment.
