Emissions reductions by mitigation measure
| Milestones | 2022 | 2030 | 2035 | 2050 |
|---|---|---|---|---|
| Cement production (Mt) | 4 160 | 4 260 | 4 140 | 3 930 |
| Clinker-to-cement ratio (tonne per tonne) | 0.71 | 0.65 | 0.61 | 0.57 |
| Kiln thermal energy intensity (GJ per tonne of clinker) | 3.6 | 3.4 | 3.3 | 2.9 |
| Share of near zero emission clinker production | 0% | 8% | 27% | 93% |
| CO2 captured (Mt CO2) | 0 | 170 | 480 | 1 310 |
| Share of low-emissions fuel in thermal energy use | 5% | 30% | 49% | 86% |

| Hydrogen | 0% | 1% | 3% | 9% |
| Electricity | 0% | 0% | 0% | 8% |
Announced CCUS projects fall short of 2030 target
Advanced economies move first, but most of the challenge lies in emerging market and developing economies
Announced CCUS projectsinclude all facilities with a capacity larger than 0.1 Mt CO2 per year as of June 2023, and projects with an announced operation date by 2030.
