The European Union began its definitive Carbon Border Adjustment Mechanism (CBAM) in January 2026, imposing carbon costs on imported construction materials. This policy aims to align the price of imported goods with domestic standards to prevent carbon leakage.
Why it matters
CBAM converts a product's carbon intensity into a direct financial liability, forcing companies to pay for the emissions generated during material production and transport. By internalizing these costs, the mechanism incentivizes the use of lower-carbon materials in global building projects.
Steel and concrete currently represent 70% to 75% of a typical building project's embodied carbon, with construction phases accounting for up to 90% of total emissions. Following the policy start, UK structural steel prices increased 2.7% between December 2025 and January 2026.
The players
European Union
This political and economic union of 27 member states pioneered the Carbon Border Adjustment Mechanism to enforce climate standards on trade.
United Kingdom
The nation is currently developing its own carbon border policy to prevent becoming a dumping ground for high-carbon materials.
The details
Importers must now purchase and surrender certificates based on the verified emissions data of their products, with certificate prices tied to the weekly average of EU Emissions Trading System allowances. This requirement has triggered immediate price adjustments, including a 3.5% rise in steel-based sanitaryware costs and a 2.8% increase in central heating products early in 2026.
Timeline
December 2025: Baseline for tracking structural steel price increases.
January 2026: The European Union's Carbon Border Adjustment Mechanism entered its definitive phase.
March 2026: The United Kingdom launched its national Steel Strategy.
January 2027: The United Kingdom is scheduled to launch its own equivalent CBAM program.
2028: The European Union proposes expanding the carbon tax to 180 downstream products.
Market Landscape
The global construction industry is shifting toward a model where material procurement is dictated by carbon intensity rather than just market price. This transition follows the regulatory precedent set by the European Union's Carbon Border Adjustment Mechanism, which effectively forces international suppliers to de-carbonize to remain competitive.
Construction project budgets are experiencing immediate upward pressure as importers pass the costs of carbon certificates and compliance onto clients. Building owners and developers should anticipate higher upfront costs for steel and concrete as these materials face stricter emissions-based surcharges.
The takeaway
The transition to carbon-taxed imports makes transparency in supply chain emissions a necessity for project viability. Developers must prioritize early procurement and low-carbon alternatives to mitigate the financial impact of expanding global carbon regulations.
What happens next
The United Kingdom is scheduled to launch its own Carbon Border Adjustment Mechanism in January 2027, and the European Union plans to expand its carbon tax to 180 downstream products in 2028.
