Produce low-carbon cement with precise monitoring. Optimise with CarbonOS.

Carbonova connects kiln, mill and energy data to CarbonOS, a platform of AI agents that calculates emissions per tonne of clinker and cement, flags drift in thermal and electrical energy use, and compares alternative-fuel and clinker-factor scenarios by their effect on cost and CO₂. The same dataset produces carbon reports for regulators, customers and investors, with an audit trail back to the source.

About 60% come from calcining limestone to make clinker, which releases the CO₂ held in the raw material, and most of the rest comes from burning fuel in the kiln (World Economic Forum, 2023). That is why the two biggest levers are the clinker factor, 72% on global average according to the same source, and the kiln’s fuel mix.

UK cement plants are covered by the UK Emissions Trading Scheme, and the UK CBAM, which starts on 1 January 2027, puts a carbon price on imported cement, alongside aluminium, fertiliser, hydrogen, and iron and steel. Importers must register once their CBAM goods exceed £50,000 over a rolling 12 months, and the first return and payment are due by 31 May 2028.

Under UK ETS monitoring rules, CO₂ sent to a permitted storage site is deducted from a plant’s reported emissions, so every tonne captured and stored cuts the allowances it must surrender. Carbonova’s planning agent compares capture with fuel switching and clinker reduction on the plant’s real data and ranks the options by cost per tonne of CO₂ avoided.

Using your plant’s real data, the planning agent simulates the cost and CO₂ effect of replacing fossil fuel with waste-derived fuel or biomass and of replacing part of the clinker with materials such as slag, pozzolans or limestone, then ranks the options by cost per tonne of CO₂ avoided. As a benchmark, waste-derived fuels already supply 52% of the heat in French cement kilns (France Ciment, 2023).

Yes. Every value has lineage back to its source data, a versioned emission factor and a change history, in line with the ISO 14064-3 verification standard. The same dataset serves regulatory reporting, ISSB-aligned disclosures, the emissions data EU importers need for CBAM and customer requests for product carbon footprints.
