In Japan, which will have realized a reduction of 80% of CO 2 emissions by 2050,
the total CO 2 emissions would be 250 million tons and the GDP ¥600 trillion. The
CO 2 emissions per ¥1 billion value-added (hereinafter referred to as “CO 2 emissions
per value-added”) is expected to be 420 tons, which is a significant reduction from
the current 2400 tons.
Table 5.7 shows the average emission of industries per value-added, which is
calculated to decrease from current 1160 to 210 tons.
Let’s look at each of these industries individually. Although the value-added of
“information and communication” is estimated to be 1.7 times larger than current
level, this simulation is based on a conservative assumption where the annual average growth rate is 1.5%, so there is a possibility of further expansion.
Similarly, under the “medical care and welfare” category, given the recent progress in medical equipment, medical technology, treatment modalities, and the
amount of wealth possessed by the elderly people, the number of people willing to
pay extra for receiving treatment is expected to increase. If we have a comfortable
hospital environment in combination with high medical technology in Japan, the
demand from overseas will also increase, which could double the current valueadded. If Japan’s state-of-the-art medical system is constantly adopted and flexible
management becomes possible, this value will be further increased.
In the medical field, the percentage of electricity use is large, so even the low
carbonization of electricity alone will lead to a considerably large low carbon industry, and it is still essential to achieve high insulation in hospital buildings and further
low carbonization of various medical equipment. The amount of power required by
