the heavy particle radiotherapy equipment used for cancer treatment is as high as
3000 kW with one unit. The electricity cost accounts for a considerable part of the
total treatment cost (¥3 million per person), and the amount of CO 2 emissions is
large, yet in principle, it is possible to save a substantial amount of electricity. For
low carbonization of not only heavy particle radiotherapy equipment but also for the
medical and welfare sector to be achieved, it is important to develop a system using
various high functional materials. This is also a suitable field to leverage Japan’s
strengths.
By incorporating the themes discussed above into concrete issues and working to
solve each issue, it is possible to achieve both targets of economic expansion and
low carbonization. Given the accelerated changes in future society, we consider that
enhancing the “education and research technology services” sector is a particularly
important approach. To be able to respond to the ever-changing society, it is necessary to have an educational system that allows everyone to acquire new knowledge
and ways of thinking and continue learning. Such a system will inevitably grow as
an industry. Furthermore, the expansion of research service sectors such as society
and engineering or science to drive this social change and to discover the seeds such
as new technologies and systems for a new society will similarly advance. There is
a possibility that the value-added in these sectors may grow beyond the scope of
these estimations.

Industries
Lastly, let us consider low carbonization of all industries. The CO 2 emissions data
per value-added in 2013 and 2050 are interspersed, and Fig. 1.13 is graphically
presented once again (Fig. 5.2). The vertical axis shows CO 2 emissions per unit
value-added, while the horizontal axis shows value-added.
In Table 5.6a, 5.6b and 5.6c, the CO 2 emissions of households that do not produce value-added are ranked number 38 of domestic sector. Fig. 5.2 is provided to
demonstrate the relationship between value-added of the industrial sector and CO 2
emissions, by allocating the total CO 2 emissions of the household sector into
62.8 million tons to the petroleum and coal product manufacturing industry, and
into 161.3 million tons to the electricity, gas, and water supply industry.
This is how Fig. 5.2 should be interpreted. In the case of 2013, the value-added
(GDP) on the horizontal axis is the highest at ¥523 trillion, and the lowest plot on
the vertical axis where CO 2 emissions per unit value-added is 23,000 tons/¥1 trillion
is the services industry. In Table 5.6c, it is ranked at 37th, the lowest plot. If ¥27 trillion of value-added of the services industry is deducted, the remaining GDP is
¥496 trillion. The plot at ¥496 trillion on the horizontal axis and at 76,000
tons/¥1 trillion on the vertical axis in Fig. 5.2 is the public sector.
