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.

Cement plants are in the EU Emissions Trading System, and their free allocation is being phased out: under current law it falls by 2.5% in 2026 and again in 2027, on a path to zero by 2034, while a July 2026 Commission proposal would slow that phase-out. Since 1 January 2026, imported cement also carries a CBAM certificate obligation on its embedded emissions.

The CBAM certificate price, which follows EU ETS auction prices, averaged €82.32 per tonne in the third quarter of 2026. With free allocation shrinking each year, every tonne of CO₂ avoided through alternative fuels, a lower clinker factor or kiln efficiency turns into cash. Carbonova’s planning agent ranks those measures by cost per tonne avoided on the plant’s real data.

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.
