Net zero is no longer just about what organisations promise, it’s about what they can prove. The UK’s net zero journey is moving from ambition to accountability. Targets and strategies still matter, but the market is asking a sharper question – can you evidence it? In this next phase, being able to show progress will matter as much as making the promise.
Why CBAM matters
That is why the Carbon Border Adjustment Mechanism, or CBAM, deserves more attention than another regulatory acronym. From 1st January 2027, the UK Government has confirmed it will apply to selected imports from the aluminium, cement, fertiliser, hydrogen, iron and steel sectors, helping ensure imported carbon intensive goods face a comparable carbon price to UK-produced equivalents.
Businesses that wait until CBAM appears in tender questions may already be on the back foot. By then, the evidence clients expect could take months to build.
Carbon is becoming commercial
For construction, infrastructure and major project supply chains, the direction is clear. Carbon is moving from sustainability reports into procurement strategy, bid evaluation, material choices and supplier conversations. Expect more questions about where materials come from, supplier declarations, embodied carbon data, transport assumptions and reduction plans.
Carbon starts before site
Carbon does not begin on site. It is already embedded in the steel, cement and aluminium that shape projects, as well as the sourcing decisions, specifications, manufacturing processes and transport routes behind them.
Too often, that information is left until teams are already focused on price, programme and delivery. CBAM challenges that habit by pushing organisations to understand where materials come from, how they are produced and how confidently the associated emissions can be evidenced.
What this means for SMEs
For SMEs, this could feel like another layer of complexity: another acronym, another compliance burden and another procurement pressure. But it could also become an opportunity for businesses that are close enough to their supply chains to move quickly.
Early action as a competitive advantage
Early action can turn carbon clarity into competitive advantage. Not by claiming every answer, but by showing clients where carbon risks sit, how suppliers are being mapped and what evidence is already in place. For many SMEs, the advantage may be speed – getting closer to supplier data, strengthening bid responses and building a clearer evidence base before clients ask for it.
Bid readiness needs to evolve
This is where bid readiness needs to evolve. A strong bid library is no longer just a repository of policies, CVs and case studies. It needs to operate as an evidence base: carbon data, supplier mapping, material information, reduction actions and a clear story that connects sustainability commitments to real project delivery.
Preparing for carbon proof
CBAM may begin at the border, but its influence will be felt much earlier, in sourcing strategies, prequalification responses, tender submissions and supplier conversations.
The question is no longer whether carbon evidence will matter in bids. It is how ready your organisation will be when clients start asking for it. Those that prepare now will be better placed to compete in a market where clear carbon evidence is becoming part of commercial trust.
How CloudNine can help
At CloudNine, we help organisations make that shift: responding to today’s opportunities while getting ready for the questions evaluators, clients and supply chain partners will ask tomorrow.
