The British government’s inability to secure a carbon tax exemption from the European Union before Christmas will result in substantial new paperwork requirements for manufacturers starting in January. Brussels has confirmed that the anticipated carve-out from the carbon border adjustment mechanism will not be implemented by year-end, with industry experts predicting relief won’t come before Easter 2025.
Exporters of approximately £7 billion worth of goods to the EU will need to provide detailed documentation of carbon emissions throughout their manufacturing processes. The requirement affects a broad range of products, including steel and aluminium manufactures such as washing machines and car parts, alongside fertilizer, cement, and energy exports. Manufacturing trade body Make UK has characterized the forthcoming paperwork as “extensive” and warned of significant negative impacts on businesses, particularly smaller operations.
The timing of the EU’s negotiation mandate approval—early December—made achieving a pre-Christmas agreement politically impossible, requiring coordination across all 27 member states with varying degrees of interest in UK-specific arrangements. Government representatives are now advising businesses to prepare for the carbon border adjustment mechanism’s implementation from January, with support and information available through the Department for Business and Trade.
Industry representatives have highlighted both the administrative burden and competitive implications of these new requirements. Frank Aaskov of UK Steel describes the documentation as representing a “significant negative impact” and “quite a burden” especially for small and medium-sized enterprises. The financial implications, while not immediately devastating, could prove critical in competitive markets. For instance, the €13 per tonne tax on hot rolled wire—material costing around €650 per tonne—might seem modest, but in the ruthless steel market where Chinese imports are highly competitive, margins of just €5 per tonne can determine contract outcomes.
British steel producers already navigate challenging circumstances, including 50% EU import tariffs introduced as a response to American trade measures. The negotiation pathway involves two distinct stages: establishing terms of reference, followed by discussions on emissions trading system compatibility. Although actual tax payments won’t be required until 2027 and could potentially be cancelled through successful negotiations, the immediate administrative requirements take effect in January. EU Climate Commissioner Wopke Hoekstra has described discussions with UK officials as productive and suggested immediate costs will be minimal given Britain’s existing decarbonization efforts, but emphasized the necessity of following proper procedures step by step. The UK government continues to prioritize securing a carbon linking agreement to protect the substantial export market.
