CO₂ monitoring and visualization
CO₂ monitoring and visualization involve measuring atmospheric concentrations using satellites and ground-based sensors, enabling the mapping of emissions from urban and industrial areas as well as absorption by forests and farmland. This technology provides a reliable foundation for emissions trading and carbon credits, enhancing their credibility. As a result, scientifically validated data is driving the adoption of effective emission reduction strategies. The integration of monitoring and visualization plays a key role in accelerating the transition toward a sustainable society.

CCUS
CCUS (Carbon Capture, Utilization, and Storage) refers to technologies that capture emitted CO₂ and either utilize it as a resource or store it underground. CO₂ can be extracted from power plant and industrial flue gases using chemical absorption or membrane separation, and efforts are also underway to capture CO₂ directly from ambient air. In terms of utilization, methods include producing synthetic fuels and chemicals from CO₂, or incorporating it into concrete for use as a construction material. For storage, CO₂ is injected into aquifers or depleted oil and gas fields for long-term sequestration. CCUS is a foundational technology that supports decarbonization in hard-to-abate industries.

Carbon-free electricity
Carbon-free electricity refers to power generated without emitting CO₂. In solar energy, the development of lightweight and highly efficient perovskite solar cells is advancing, while offshore and floating wind turbines are enabling large-scale wind power generation. Research into marine energy sources such as wave and tidal power, is also progressing, positioning them as promising next-generation renewable energy options. Additionally, nuclear fusion power is being actively studied and is expected to become a future source of clean electricity. By combining a diverse mix of energy sources, we are establishing a solid foundation to support the decarbonization of society as a whole.

Decarbonizing industrial processes
Industrial processes such as steel, chemical, and cement production consume large amounts of energy and emit significant amounts of CO₂. To decarbonize these sectors, electrification—replacing heat and manufacturing processes with electric power—is being advanced. In steelmaking, research is progressing on electric arc furnaces and hydrogen-based direct reduction. In the chemical industry, initiatives are underway to drive reactions using electricity derived from renewable energy sources. Furthermore, upcycling efforts that convert waste plastics and by-products into new products are gaining momentum. Transforming these processes enables both CO₂ reduction and resource circulation in industry, supporting sustainable manufacturing.
