Research and Development Targets for 2030
1. Concrete Realize below targets for production, transportation, and construction of concrete. - CO2 emissions reduction: 310-350 kg/m3 (of which CO2 fixation is 120-200 kg/m3).
- Cost equal to or lower than that for existing products.
Develop quality control methods and realize international standards for concrete produced with maximized levels of CO2 emissions reduction and CO2 fixation. 2. Cement
Develop CO2-recovering cement production process and meets below standards: - Recover at least 80% of CO2 emitted in pre-heaters.
- Reduce costs in comparison with conventional amine scrubbing chemical absorption method.
Develop technologies to meet following standards for producing carbonates from recovered CO2 and using these as raw materials for cement. - Realize at least 400 kg of fixed CO2 per ton of carbonates, by extracting at least 10% of calcium oxide from wastes.
- Produce carbonates from recovered CO2 at cost roughly 5 times market price for conventional limestone.
- Develop technology utilization guidelines in response to expanded use of carbonates.
Develop quality control methods and realize international standards for concrete produced with maximized levels of CO2 emissions reduction and CO2 fixation.

Assumptions for estimates of CO2 reduction effect
- Estimates of CO2 reductions calculated for both concrete and cement.
- Figures based on estimates used in graph regarding market conditions for concrete included in chapter titled “Potential increase in market size due to implementation of strategic actions” in Carbon Dioxide Utilization (CO2U) ICEF Roadmap 1.0.
- Figures based on estimates for 2050 used in Figure 4: Cement production by region contained in report titled “IEA - Technology Roadmap - Low-Carbon Transition in the Cement Industry.” Estimates assume that dissemination rate of concrete produced with maximized levels of CO2 emissions reduction and fixation will total 4% and that cement production processes capable of recovering carbon will be fully utilized.
Assumptions for estimates of economic effect
- Figures based on estimates for 2030 used in Figure 4: Cement production by region contained in report titled “IEA - Technology Roadmap - Low-Carbon Transition in the Cement Industry.” Estimates assume that dissemination rate of concrete produced with maximized levels of CO2 emissions reduction and fixation will total 0.1%.
- Technologies are expected to be used in approximately 10% (or 5 kilns) of all kilns deployed in domestic cement production plants (total of 30 plants, 51 kilns).
- Cost of equipment installation cost is expected to total 20 billion yen per kiln.
- 10% of domestic market for mixed cement is expected to be acquired.
- Figures based on estimates for 2050 used in Figure 4: Cement production by region contained in report titled “IEA - Technology Roadmap - Low-Carbon Transition in the Cement Industry.” Estimates assume that dissemination rate of concrete produced with maximized levels of CO2 emissions reduction and fixation will total 4%.
- Global supply of cement is expected to be replaced by 2050 with CO2-mixed cement produced under this R&D project, and that, by 2050, current cement production facilities are expected to be replaced by facilities necessary for this type of cement production (estimated total of approximately 5 billion tons in 2050).
