One table answers the budget question for the decade. Regulation (EU) 2023/956 — law, not scenario.

*At constant EUA €77.4 and typical intensities (0.7 / 1.9 t CO2/t) — your benchmark position shifts the absolute level, the SLOPE is fixed by law. Download: prices CSV; per-industry tables on each industry page.
You don't get «97.5% of your emissions» free — you get benchmark × activity level × CBAM factor: the benchmark is the average of the top-10% most efficient EU installations per product. Efficient plants may cover most of their real emissions in 2026; laggards already pay the gap. The factor column above is what shrinks to zero for everyone.
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:
Every efficiency project gains a rising carbon revenue: a tonne avoided is worth €77.4×2.5% this year but €77.4×100% from 2034 — and every year in between, per the table. Discount that stream and most sub-€40/t measures self-finance. That's the entire strategic content of the table.
