«We've always had free allowances» and «we have no carbon price here» are both about to stop being true. Find your scenario.
Until 2025 free allocation covered most of your benchmark emissions, so the EUA price was mostly someone else's problem. From 2026 the payable share is real money: at €77.4/t, a 500,000 t/yr cement plant (~350,000 t CO2) pays ≈ €0.7M in 2026, ≈ €13M in 2030 and ≈ €27M in 2034. That line item will outgrow your maintenance budget. Every tonne of CO2 you eliminate now compounds for nine years.
You pay nothing at home — your importer pays CBAM at €75.36/t on a rising share of the embedded emissions in your product. In practice the cost lands in your price negotiations immediately: EU buyers already ask for verified emissions per tonne. Lower embedded CO2 is becoming a commercial spec, like purity or tolerance. The exporter with 1.6 t/t aluminium beats the one with 2.1 t/t by €75.36×0.5×phase-in on every tonne.
Boilers, kilns, heat exchangers, valves and steam lines lose energy continuously. Inzonex makes patented (UK GB2508992.1) removable modular insulation — snap-fastened covers engineered per temperature tier, not generic off-the-shelf jackets:
No federal price, and California/RGGI may not touch you. Two ways this still reaches you: (1) anything you ship to the EU in CBAM sectors gets the border price; (2) buyers' Scope-3 programmes (CSRD-driven) increasingly require supplier emissions data — your CO2 per tonne is being compared today even where it isn't priced.
Power never had free allocation in the EU — you already pay full price, ≈€28/MWh on gas CCGT and ≈€73/MWh on coal at €77.4/t. What changes is the merit order and the heat-rate math: every 1% of efficiency (or recovered heat) is now worth ≈€0.3-0.7/MWh in carbon alone. Efficiency projects that missed hurdle rates at €30/t clear them at €77/t.
In all four scenarios the cheapest response is the same: cut the tonnes that cost nothing to cut. Heat loss from uninsulated valves, flanges and equipment is typically 2–5% of fuel-related CO2, recoverable with removable insulation at <2-year payback — before any process redesign, fuel switch or CCS. Run the numbers for your plant.
