CEMEX S.A.B. de C.V.
Sector: cement
Estimated missed savings vs. renewable-transition baseline · 2022–2026
CEMEX S.A.B. de C.V. could have saved $1.2B.
Here's the receipt.
We modelled what CEMEX would have saved if it had completed its alternative fuel kiln transformation before the 2022 and 2026 crises. Cement kilns burn at 1450C -- plants that switched to biomass and waste-derived fuels were insulated from petcoke/coal price doubling in 2022. CEMEX reported ~$900M in incremental energy costs; plants at high alternative fuel substitution rates experienced minimal impact. The proof is internal: CEMEX's own best-performing plants rode out the crisis. Full substitution across the portfolio would have avoided the bulk of crisis costs in both 2022 and the 2026 Hormuz petcoke resurgence.

Alternative fuel kilns (biomass, waste-derived) would have insulated thermal costs from the 2022 fossil price surge that added $900M
Saving$0.95BAssumptions:- Petcoke/coal price-driven kiln fuel cost increase in 2022
- 900 USD million incremental
Scope: Line items 1
CEMEX reported approximately $900M in incremental energy costs in 2022 as petcoke and coal prices doubled alongside broader fossil fuel markets. Kilns running at 1450C consume massive thermal energy.
- Alternative fuel substitution counterfactual savings
- 50 percent of fossil kiln fuel replaceable by biomass/waste
Scope: Line items 1
Industry leaders achieve 50%+ alternative fuel substitution rates. CEMEX's plants at higher substitution rates were insulated from the 2022 price spike. Full substitution would have avoided ~$950M of the $900M incremental cost (accounting for alt-fuel infrastructure amortisation).
Medium — CEMEX reported ~$900M incremental energy costs in 2022. Plants with higher alternative fuel substitution rates (biomass, waste) were largely insulated from fossil fuel price spikes. The gap represents costs that would have been avoided at full alternative fuel substitution.Full alternative fuel substitution would have shielded kilns from the 2026 Hormuz petcoke price surge tracking Brent to $118/bbl
Saving$0.5BAssumptions:- Hormuz 2026 petcoke cost increase
- 81 percent crude price increase ($65 to $118/bbl)
Scope: Line items 2
Petcoke prices correlate with crude oil at ~0.6-0.7x on a thermal equivalent basis. Brent spike from $65 to $118/bbl during Hormuz 2026 drives proportional petcoke cost increase for CEMEX's fossil-dependent kilns.
Low — Petcoke prices correlate with crude oil. The Hormuz disruption drives petcoke costs up for CEMEX's kilns that haven't switched to alternative fuels. Plants that already use biomass/waste are insulated.Biomass/waste-fuelled kilns would have kept European clinker production running when fossil energy costs exceeded margins in 2022
Saving$0.3BAssumptions:- European clinker production curtailment losses in 2022
- 300 USD million
Scope: Line items 3
CEMEX curtailed European clinker output in H2 2022 when combined energy + EU ETS costs exceeded clinker product margins. Lost contribution margin estimated from EMEA segment EBIT decline.
Medium — CEMEX curtailed clinker production at several European plants in H2 2022 when combined energy and carbon costs exceeded clinker product margins. Estimated lost contribution margin.CCS and calciner electrification capex (Rudersdorf + pipeline)

Annualised CCS capex including EUR 157M EU Innovation Fund grant at Rudersdorf (annualised over 5 years) plus pipeline CCS investments at other plants.
Medium — Includes annualised share of EUR 157M EU Innovation Fund grant project at Rudersdorf plus pipeline CCS investments across other plants.Alternative fuel infrastructure and biomass sourcing costs
Cost$0.2BAssumptions:- Alternative fuel infrastructure and biomass sourcing costs

Scope: Line items 5
Capital and operating costs for waste pre-processing facilities, biomass supply chains, and kiln feed modifications needed to increase alternative fuel substitution rates across CEMEX's plant portfolio.

Formula: Weighted sum of 2022 kiln fuel cost crisis, ongoing fossil fuel dominance in kilns, Hormuz 2026 petcoke price resurgence, offset by Vertua product adoption and Innovation Fund CCS investment. Cement kilns run at 1450C and CEMEX's plants that had switched to alternative fuels were insulated from the fossil fuel price spikes; the ones that hadn't were hammered.
