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?

Low‑carbon construction is transitioning from niche innovation to mainstream delivery, reflecting an accelerating shift toward sustainable building design and net zero whole life carbon performance. A Nordic–Dutch start‑up has developed a cement alternative that permanently stores CO₂, enabling carbon‑negative concrete with reduced embodied carbon in materials. Such technology directly addresses the carbon footprint of construction, offering measurable gains in whole life carbon assessment and lifecycle assessment without reliance on large‑scale carbon capture infrastructure. The advance positions green construction and eco‑friendly construction as credible pathways for decarbonising the built environment.
Temporary site power is also evolving. Repurposed electric vehicle batteries are replacing diesel generators, cutting operational emissions and supporting circular economy in construction principles. With the Gold Standard’s new framework for verified carbon credits, contractors can now monetise carbon footprint reduction through measurable performance gains. This change combines resource efficiency in construction with financial incentives that accelerate sustainable building practices and reduce reliance on fossil‑based site operations.
Regulatory momentum is uneven but decisive. The Future Homes Standard sets new benchmarks for energy‑efficient buildings, low carbon design, and performance transparency, compelling supply‑chain alignment across Britain’s housing sector. By contrast, Scotland’s deferred expansion of heat‑pump deployment to 2035 risks slowing sustainable urban development and delaying market maturity for low carbon building systems. Strengthened compliance with BREEAM v7 and similar frameworks will define capital allocation, making life cycle cost optimisation and whole life carbon metrics core to project appraisal.
Labour data reveal a 28% expansion in the UK’s green workforce to 650,000 roles, yet shortages persist in modern methods of construction, envelope installation, and low‑carbon systems. Addressing these skills gaps will determine progress toward carbon neutral construction and net zero carbon buildings. Clients and developers embedding low embodied carbon materials and diesel‑free sites in procurement can secure both regulatory resilience and reputational advantage. Integrating eco-design for buildings, environmental product declarations (EPDs), and sustainable material specification across the supply chain ensures verifiable performance on building lifecycle performance, affirming environmental sustainability in construction as the sector’s defining metric.
