The UK quarrying and building materials sector is entering a new era, one where responsible sourcing is no longer simply a sustainability badge and security of supply is no longer someone else’s problem. Together, they have become central pillars of business resilience, operational continuity and long-term competitiveness.

According to sustainability specialists Dr Helen Bailey and Dr Miles Watkins, the conversation has evolved dramatically over the past two decades. What began as a compliance exercise and, later, a competitive differentiator, has now become a strategic necessity.

In an increasingly volatile world marked by geopolitical tension, climate disruption, resource constraints and growing demands for transparency, companies that fail to understand where their materials come from, and whether they will continue to arrive, risk being left behind.

“We’re making progress,” says Helen, the founder & director of The Driven Company Associates. “But responsible sourcing and security of supply are intrinsically linked. You can’t really treat them as separate issues anymore.”

A more complex supply chain landscape

The quarrying and construction materials industries have undoubtedly improved their approach to responsible sourcing over recent years. Environmental management systems are now well established, reporting requirements around issues such as modern slavery have gained traction, and major contractors increasingly demand transparency from suppliers. However, Helen and Miles argue that the challenge is becoming more complex rather than simpler.

One reason is the emergence of innovative low-carbon and bio-based construction products. While these materials can help reduce environmental impacts, they also introduce unfamiliar supply chains and new sourcing risks.

“The minerals industry understands the risks associated with extracting and processing materials from the ground,” says Miles. “But when you start introducing bio-based materials, that’s a whole new world of inquiry.” Land-use competition is just one example. Crops grown for industrial products may compete with food production, while supply chains can stretch across continents and become harder to verify. At the same time, companies face growing scrutiny over environmental claims, with greenwashing concerns creating additional risks. “It’s getting more dynamic all the time,” Miles notes. “Just as the industry has started getting to grips with responsible sourcing, a whole range of new issues has entered the mix.”

From competitive advantage to ‘hygiene factor’

A significant shift has occurred in how businesses view sustainability. Historically, responsible sourcing could provide a competitive edge. Today, it is increasingly viewed as a minimum requirement. “It’s gone from competitive advantage to a hygiene factor,” says Miles. “If you haven’t got your act together, you’re not going to be in the market.”

Major customers increasingly expect suppliers to demonstrate robust environmental, social and governance credentials. Provenance, carbon data and environmental product declarations (EPDs) have become commonplace rather than optional extras.

Helen believes this reflects a broader transformation in business thinking. “It’s moved from a compliance-led activity to something that is strategically important,” she explains. “It’s become wrapped into the business case.” This evolution is being driven not only by legislation and standards, but also by customers, investors and employees who increasingly expect companies to understand and manage supply chain risks.

The global becomes local

One of the strongest themes to emerge from the discussion is the growing influence of global events on domestic supply chains.

Climate-related disruption, energy market volatility, geopolitical tensions and transport challenges now affect even traditionally local industries such as aggregates, cement and asphalt. “The global picture now is influencing the domestic picture more than it probably has done previously,” stresses Helen, who is also the president of the Institute of Asphalt Technology (IAT) and deputy chair of the Institute of Quarrying (IQ).

The COVID-19 pandemic provided a stark illustration. Supply chain disruptions exposed vulnerabilities that many businesses had either overlooked or underestimated. Similar concerns now exist around critical industrial materials and components.

Helen cites tungsten as one example. Widely used in quarrying and construction plant equipment, prices have surged in recent years, creating significant maintenance challenges. A shortage of a relatively obscure material can suddenly affect equipment availability, operational costs and productivity. The issue is not simply about sourcing aggregates, bitumen or cement, it extends throughout the entire construction value chain. “Security of supply isn’t just about the material itself,” Miles explains. “It’s also about keeping equipment operating and maintaining uptime.”

Why local supply matters

Helen and Miles believe growing attention will increasingly focus on local sourcing and regional supply chains.

Heavy materials such as aggregates and asphalt are inherently transport intensive. Yet it remains common for materials to travel long distances despite the availability of closer alternatives. “There will be an ongoing and increasing interest in local supply,” says Miles.

This trend may eventually challenge existing specifications and procurement practices. In some sectors, highly prescriptive requirements have historically limited the use of locally available materials, potentially creating avoidable transport emissions and supply vulnerabilities.

The debate is equally relevant for cement production. While importing cement may offer short-term economic advantages, both experts argue that maintaining domestic production capacity remains critical. “We don’t want to be in a situation where we don’t have any cement,” says Miles. “On a normal footing it’s inconvenient. On a military footing it’s a total disaster.”

Helen and Miles emphasise a growing construction materials industry recognition that resilience and self-sufficiency must be considered alongside carbon reduction and cost efficiency.

The continuing importance of BES 6001

At the heart of responsible sourcing in the UK construction materials sector sits BES 6001, the BRE’s responsible sourcing standard.

Watkins, the original author of the standard, explains that its origins date back nearly two decades. It was initially developed to allow concrete products to compete fairly with timber in sustainability assessment schemes. At the time, sustainably sourced timber could gain additional credits in building assessment frameworks, while concrete lacked an equivalent responsible sourcing mechanism. The result was BES 6001.

Since then, the standard has become deeply embedded within construction supply chains, particularly among major contractors. “It’s very hard to sell concrete into tier-one projects unless you’ve got responsible sourcing certification,” says Miles. The standard requires organisations to examine their supply chains, assess risks, understand material provenance and implement robust management systems. Over time, it has driven wider adoption of internationally recognised standards covering quality, environmental management and health and safety.

Miles believes BES 6001 has played an important role in elevating standards across the sector. “It has probably done quite a lot to raise management quality and operational quality throughout the domestic supply chain.”

Version 4: More than environmental performance

The latest version of BES 6001 reflects how responsible sourcing continues to evolve.

Version 4 places greater emphasis on social issues, labour standards and supply chain transparency. It also strengthens scrutiny of materials sourced from countries with weaker regulatory frameworks.

Rather than creating an exclusive certification available only to industry leaders, BES 6001 follows what Miles describes as a “ladder” approach. Companies can begin with foundational processes and progressively improve their performance through documented evidence, reporting and independent verification. “The principle is to get companies onto the ladder,” Miles explains. “If you don’t start, you don’t get any better.”

Helen describes this as a continuous improvement model rather than a compliance exercise. “It’s really a management discipline,” she says. Importantly, both experts emphasise that responsible sourcing standards alone cannot solve all supply chain risks. Geopolitical disruptions, nationalisation of assets, trade disputes and extreme weather events sit outside the direct scope of any certification scheme. However, organisations that understand their supply chains are better positioned to identify vulnerabilities and respond effectively.

Circularity as a resilience strategy

One of the most intriguing developments is the way supply chain pressures are accelerating circular economy thinking.

As the availability and cost of certain materials become more problematic, businesses are increasingly exploring reuse, recovery and alternative solutions. Rather than being motivated solely by sustainability objectives, many companies are now being driven by economic necessity.

The tungsten example illustrates this trend. Rising costs are encouraging companies to find ways to extend component life, repurpose materials and improve resource efficiency. “Responsible sourcing and security of supply are challenging the way people behave and think,” Helen says. This shift, she argues, could accelerate circularity faster than traditional sustainability initiatives alone.

Managing risk in an age of transparency

The digital age has fundamentally changed the risk equation for businesses.

Information travels instantly. Supply chains are scrutinised more closely than ever. Reputational damage can emerge rapidly. Miles describes this as “the speed of reveal”. “Anyone can find anything out about anyone really, really quickly,” he says.

This heightened transparency creates both opportunities and challenges. While it encourages higher standards, it can also make companies more cautious about innovation.

Fear of making mistakes can lead to “green hushing”, where organisations avoid discussing sustainability initiatives altogether, or discourage experimentation with potentially beneficial technologies.

Yet both experts stress that avoiding risk entirely is not an option. “We must never stop trying,” says Miles. “What we need people to do is go in with their eyes open.”

What happens if industry fails to act?

The consequences of neglecting responsible sourcing and security of supply are potentially severe. Supply interruptions can delay projects, increase costs and damage business reputations. Ethical failures can trigger public scrutiny and lost contracts. For an industry that underpins critical infrastructure, the implications extend well beyond individual companies. “We won’t be able to build stuff,” Miles says bluntly.

Public infrastructure projects, housing developments, roads, bridges and essential services all depend on reliable material supply chains. Failure to manage sourcing risks could ultimately cost taxpayers significant sums while delaying nationally important projects.

Miles thinks that new Labour Prime Minister Andy Burnham’s desire for more nationalisation of key UK industries and more devolved powers to the English regions may have a positive impact on responsible sourcing and security of supply in the construction materials sector.

Helen and Miles also support the industry-championing work of the Mineral Products Association (MPA), the trade association for the aggregates, asphalt, cement, concrete, dimension stone, lime, mortar and industrial sand industries, which has long urged the UK Government to stop taking domestic material supply for granted, warning that high energy costs, planning system delays and carbon leakage risks threaten the security of essential construction resources like aggregate and cement.

The road ahead

For Helen, the ultimate measure of success is straightforward.

Responsible sourcing and security of supply must become business as usual. The goal is not simply certification, compliance or ticking boxes. It is embedding supply chain awareness, risk management and long-term thinking throughout organisations. This is not a challenge with a fixed endpoint. As Helen notes, responsible sourcing is a “living, breathing” process rather than a destination.

Supply chains will continue to evolve. New materials will emerge. Climate risks will intensify. Geopolitical realities will shift. Expectations around transparency will only increase.

The companies that thrive will be those that understand the interconnected nature of these challenges and respond accordingly.

As the quarrying and construction materials sectors face an increasingly uncertain future, one thing is becoming clear: responsible sourcing is no longer merely about ethics and sustainability. It is about resilience, competitiveness and ensuring the materials needed to build Britain’s future remain available when they are needed most.
