Regarding the "carbon tax" that is levied according to the amount of carbon dioxide emissions, the Ministry of the Environment commissioned a research institute to analyze the economic impact of introducing it, and found that tax revenues could be used to spread energy-saving technologies. It was found that the results showed that economic growth and reduction of greenhouse gas emissions could be achieved at the same time.
While aiming to realize a "decarbonized society" by 2050, the Ministry of the Environment is considering "carbon pricing," in which businesses and households bear costs according to carbon dioxide emissions.
As part of this, we commissioned two research institutes to analyze the impact of the "carbon tax" on the economy, and showed the results of the impact of introducing it next year as of 2030.
Of these, the National Institute for Environmental Studies analyzes four patterns from 1,000 yen to 10,000 yen per ton of carbon dioxide, and even at the highest of 10,000 yen, the impact on GDP = gross domestic product is less than -1%. It is supposed to be suppressed.
In addition to reducing carbon dioxide emissions, if the introduction of energy-saving equipment is promoted, it will lead to economic growth in the long run, and if tax revenues are used to popularize energy-saving technologies, the economic effect will be significant. It is said that it will become more prominent, and it is said that emission reduction and economic growth can be compatible.
In addition, the Development Bank of Japan Group's think tank made a trial calculation at a tax level of 1,000 to 10,000 yen per ton of carbon dioxide, and as a result, half of the tax revenue was allocated to private capital investment. We analyze that it may lead to growth in GDP.
The Ministry of the Environment has decided to further study "carbon pricing" with reference to these analysis results.
