Workshop Series: Socially Responsible Business Practice in Denmark’s Sustainable Construction Transition

Denmark’s construction sector stands at a critical juncture. The country’s ambitious, preliminary climate goals, a 70% reduction in CO₂ emissions by 2030, depend heavily on the construction sector’s transformation. Yet this green transition risks being built on unstable foundations if workers’ rights are compromised along the way.

With foreign workers now comprising 26% of the construction workforce (up from 8% in 2013), long and opaque supply chains, and approximately 23% of companies employing foreign staff at higher risk of social dumping, the sector faces significant challenges. Despite Denmark’s progressive regulatory frameworks, social dumping persists. Posted workers often earn significantly less than their Danish colleagues for identical work. Complex subcontracting chains obscure accountability. And workers, particularly those from abroad, have limited voice in the transition reshaping their jobs and livelihoods.

Meanwhile, enforcement is strengthening: new posted worker protections (2025–26), enhanced authority to halt projects for repeated violations (‘Entreprenørstop’, January 2026), mandatory housing standards, and EU Taxonomy requirements for social minimum safeguards are creating both pressure and opportunity for the sector to act.

Why these three workshops?

This workshop series addresses the interconnected challenges of ensuring Denmark’s green transition advances, rather than compromises, workers’ rights and fair labour practices. Each workshop builds on the previous, moving from establishing the foundations to diagnosing persistent challenges to integrating social and climate goals.

Workshop 1: Starting with the foundation: working clauses (11th May)

Working clauses in construction contracts are the essential and practical instruments that translate responsible business commitments into enforceable standards. They establish binding requirements on wages, working conditions, and subcontractor accountability, protecting workers, ensuring fair competition, and preventing the exploitation of labour. Without effective working clauses, every other ambition in responsible construction remains aspirational.

Yet one core problem persists: social dumping is still used to gain an unfair competitive advantage, effectively ‘stealing’ from both the public treasury and law-abiding businesses. Recent data from the Danish Tax Agency (Skattestyrelsen) reveals that nearly half of all inspections since 2020 have uncovered tax evasion or labour violations, often facilitated by opaque subcontracting chains and the exploitation of foreign labour.

The legislative landscape fundamentally changed in January 2026. With the introduction of the ‘Contractor Stop’ (entreprenørstop), a single subcontractor’s repeated safety or labour violations can now legally shut down an entire construction site, regardless of the main contractor’s direct involvement. Working clauses are no longer a compliance exercise; they are the first line of defence, an essential risk-management tool for responsible businesses across the supply chain. For the segment of the industry that voluntarily aims for excellence, these clauses are not ‘red tape’, they are market protection.

This is why the series begins here: before we can diagnose what is failing or integrate social and climate goals, the sector needs to align around what effective working clauses look like, what the non-negotiable minimum safeguards should be, and how different approaches, from municipal frameworks to new industry-led standards, compare in practice.

Workshop 2: Diagnosing what persists: social dumping (25th August)

If working clauses set the standard, why are violations still so widespread? A report from the Danish National Centre for Social Research (VIVE) found that nearly a quarter of companies employing foreign workers are at risk of subjecting them to conditions below those guaranteed by Danish collective agreements. CG Jensen, one of Denmark’s major contractors, estimates that fraud and exploitation in the sector may cost up to DKK 68 billion. And Copenhagen Municipality’s social dumping task force, which has a decade of enforcement experience, reported in 2024 that 77% of its investigated cases showed violations of labour clauses, with 83% classified as serious and an average underpayment of 58%.

These figures confirm that the challenge is structural, not marginal. The second workshop shifts from the tools to the terrain. It examines the systemic mechanisms that enable circumvention, complex subcontracting chains, letterbox companies, inconsistent enforcement, and the vulnerability of posted workers who may not know their rights or fear retaliation. It asks what responsible businesses actually need to compete fairly when others cut corners, what workers need for real protection beyond what exists on paper, and what evidence-based approaches work at scale.

This diagnosis matters because stronger legislation alone has not solved the problem. The entreprenørstop creates new pressure, but closing the gap between legislative intent and ground-level reality requires a collective understanding of where and how the system fails, and what different actors across the value chain can do about it.

Workshop 3: Connecting the ambitions: green and fair together (24th September)

Denmark’s 70% CO₂ reduction target by 2030 is driving massive retrofit programmes, new green infrastructure, and billions in public and private investment. The construction sector is being reshaped, and with it, the conditions under which tens of thousands of workers build, renovate, and demolish.

The risk is that climate urgency overrides social standards: that the pressure to deliver on time and on budget pushes procurement towards the cheapest bidder rather than the most responsible, that new green skills benefit employers without translating into better conditions for workers, and that the EU Taxonomy’s social minimum safeguards remain a theoretical requirement rather than an operational reality.

The third workshop brings the series full circle. It connects the foundations of the working clauses from Workshop 1 and the social dumping diagnosis from Workshop 2 to the green transition’s specific demands. The question is whether Denmark’s climate investments will advance or compromise the social foundations that responsible businesses have been working to establish, and what it takes to ensure both ambitions reinforce each other.

What participants will gain

Participants who engage across all three workshops will:

• Learn practical tools for human rights due diligence in complex subcontracting chains
• Learn from frontrunners already implementing responsible practices successfully
• Future-proof operations ahead of strengthening enforcement
• Connect with committed peers across the value chain - clients, contractors, unions, and policymakers
• Shape industry standards through a dedicated platform for responsible business in the green transition
• Contribute to actionable recommendations for constructors, contractors, clients, and policymakers

By the end of the 2026 series, the partnership aims to deliver:

1) Workshop series outputs (concrete, 2026): 

• A stakeholder network actively engaged in responsible business practice dialogue 
• Documented insights on implementation challenges and what works 
• Priority areas identified for practical tool development 
• Input gathered to inform future guidance/recommendations 
• Initial definition of minimum social safeguards for the sector 

2) Partnership ambitions (longer term, ongoing 2026 and beyond)

• Practical due diligence tools tested by Danish construction companies 
• Defined minimum social safeguards for the sector 
• Concrete recommendations for policy coherence 

Who are these workshops for?

This series is designed for professionals committed to advancing responsible business practices in Denmark’s construction sector:

• Construction clients and developers whose procurement shapes market standards
• Contractors and subcontractors implementing responsible practices on the ground
• Trade unions and worker representatives ensuring solutions actually protect workers
• Municipal and public procurement bodies leveraging their market position for impact
• Industry associations and CSR practitioners driving sector-wide change
• Civil society organisations working on labour rights and just transition
