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 moving from ambition to delivery, with finance, planning and grid capacity now defining the pace of decarbonising the built environment. Climate risk is becoming a capital allocation issue, yet the gap between stated concern and investment remains severe, especially for SMEs facing a global green-finance shortfall for energy efficiency, clean technology and adaptation. For construction firms working on thin margins, net zero carbon buildings will depend on bankable resilience, credible life cycle cost analysis and procurement models that reward whole life carbon performance rather than short-term lowest cost.
The UK’s planned major electricity substation in Tees Valley underlines the scale of green infrastructure required to support industrial decarbonisation, heat electrification, energy-efficient buildings and low carbon construction materials. Grid reinforcement is critical to net zero carbon delivery because sustainable building design relies on clean power as much as sustainable material specification. Without resilient energy networks, low carbon design, renewable building materials and green building products cannot deliver meaningful carbon footprint reduction across the built environment.
Planning reform could accelerate retrofit, renewable infrastructure and sustainable urban development, provided faster approvals do not weaken scrutiny of embodied carbon, nature, resilience and the environmental impact of construction. Whole life carbon assessment, lifecycle assessment and life cycle thinking in construction should sit at the centre of decision-making, with BREEAM, BREEAM v7 and environmental product declarations (EPDs) helping clients compare embodied carbon in materials and building lifecycle performance. Speed must support high-quality sustainable design, not simply move weak schemes through the system faster.
The worsening climate outlook, including warnings on ice loss and a possible 2.6C warming trajectory, reinforces the need for eco-design for buildings that are resilient to future extremes rather than historic weather patterns. Environmental sustainability in construction now requires circular economy principles, circular economy in construction, end-of-life reuse in construction and resource efficiency in construction to reduce the carbon footprint of construction. The sector’s pragmatic next phase is clear: net zero whole life carbon, circular construction strategies, low embodied carbon materials and sustainable building practices must become standard practice in green construction, eco-friendly construction and carbon neutral construction.
