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 sustainable construction sector faces an intensifying test of credibility as shifting climate policies and volatile funding threaten progress toward net zero carbon buildings across the UK. A potential reduction in energy efficiency support could impede the delivery of low carbon design strategies and undermine the government’s commitment to environmental sustainability in construction. With the built environment generating roughly 40% of national emissions, the withdrawal of financial incentives risks increasing the carbon footprint of construction and delaying progress on whole life carbon assessment and lifecycle assessment targets. Effective policy continuity remains crucial for maintaining sustainable building design and measurable carbon footprint reduction.

At the international level, the COP30 debate on climate finance sharpened focus on equitable access to funds that can advance low carbon building projects and circular economy in construction models across developing regions. Debt-free financing may enable the adoption of renewable building materials, eco-design for buildings and localised low embodied carbon materials, empowering communities to engage in sustainable building practices aligned with whole life carbon principles. These pathways reinforce a broader transition toward resource efficiency in construction, where life cycle cost analysis and end-of-life reuse in construction become key factors in sustainable material specification.

Corporate accountability continues to lag. Fewer than half of major global firms have science-based targets, limiting the pace of decarbonising the built environment. The construction supply chain’s dependence on embodied carbon in materials and complex procurement structures highlights the urgency of integrated whole life carbon assessment frameworks. Emulating cross-sector collaborations such as those in fashion industry decarbonisation efforts could stimulate sector-wide adoption of circular construction strategies and carbon neutral construction approaches guided by BREEAM and BREEAM V7 standards.

Artificial intelligence now enters the conversation as a driver of sustainable design and building lifecycle performance optimisation. Data-driven modelling can significantly improve energy-efficient buildings and enhance life cycle thinking in construction. Yet digital tools must be deployed within a low-impact construction framework to ensure resilience and minimise environmental impact of construction.

Sustainable construction stands at a crossroads defined by financial equity, governance stability and the need for measurable carbon reduction. The industry’s capacity to embed circular economy principles and net zero whole life carbon targets into every stage of design, specification and operation will determine not only environmental outcomes but also the long-term viability of the global green construction agenda.
