Off Brazil's northeastern coast, where the sediment-heavy water of the vast Amazon River tips out into the Atlantic, are two very different types of treasure. The first is an ecological gem: a 3,600 square-mile deepwater coral reef discovered less than a decade ago. The second treasure puts the first in immediate danger. Billions of barrels of oil may lie in the ancient sediments beneath the seabed, and licenses have just been approved to drill there. A few hundred miles north, off the coast of Guyana, companies are already pumping around 650,000 barrels of oil a day from a huge deep-water reservoir discovered in 2015. The find has transformed this rainforest-carpeted country into the planet's newest petrostate and highest oil producer per capita. Several thousand miles inland to the south, the wide, dusty plains of western Argentina's Vaca Muerta — "dead cow" in English — are dotted with oil wells. Fossil fuel production from this enormous shale deposit has boomed over the past decade, putting it on track to produce more than a million barrels a day by 2030, analysts predict. They are three very different countries: an economic behemoth with an environment-championing president, a biodiversity hotspot with high rates of poverty and an economically volatile country led by a chainsaw-wielding climate denier. Yet they are united in their quest to expand oil production, arguing it's vital to their economic and social development. This new fossil fuel boom is happening just as the impacts of the climate crisis — driven by fossil fuels — are beginning to bite in ever more alarming ways. People in South America are dying in fires, floods, storms and droughts made longer and more catastrophic by climate change. But as global oil demand stays strong, and other, richer, countries show few signs of scaling back, their argument is: Why shouldn't oil supply come from South America?

The UK construction industry faces a pivotal transition as mounting insolvencies and 11 consecutive months of contraction signal structural fragility in traditional contracting. Pressure is intensifying to align with the net zero carbon agenda through sustainable construction practices grounded in whole life carbon assessment, life cycle cost analysis, and embodied carbon reduction. A parliamentary committee has cautioned that inadequate government action on construction skills development jeopardises the nation’s capacity to deliver net zero carbon buildings and drive decarbonising the built environment. Without accelerated investment in training and sustainable material specification, the carbon footprint of construction will continue to rise, undermining environmental sustainability in construction.

In contrast, signs of resilience are emerging among manufacturers and specialist trades focusing on energy-efficient buildings, low carbon design, and the adoption of renewable building materials. Companies leveraging eco-design for buildings and sustainable building design principles are pursuing resource efficiency in construction and circular construction strategies to secure long-term profitability. The industry’s tentative reorientation towards green construction demonstrates an evolving understanding of building lifecycle performance, lifecycle assessment, and the importance of low embodied carbon materials in achieving sustainable building practices.

Private partnerships promoting upskilling and retrofitting, supported by preferential finance, are beginning to embed the principles of circular economy in construction and carbon neutral construction into market operations. The integration of environmental product declarations (EPDs), BREEAM and BREEAM v7 standards, and comprehensive whole life carbon accounting is advancing more transparent sustainable architecture frameworks. Unless matched by decisive government leadership closing the widening skills gap, green infrastructure progress will remain fragmented.

The prospect of a sector essential to sustainable urban development reaching net zero whole life carbon yet constrained by its own capacity deficit exposes a critical paradox in the quest for eco-friendly construction and long-term sustainability.
