To achieve the new greenhouse gas reduction target for 2030, the government has decided to expand the introduction of renewable energy and urgently consider reducing old coal-fired power in stages. However, the government will have to deal with difficult issues as to whether the goal can be achieved with little time left.

Six years ago, the government set a goal of reducing greenhouse gases by 26% toward 2030 compared to 2013, and in the basic energy plan, which is the premise, what kind of power source will be used to supply the necessary electricity? Regarding the power source composition,


▽ renewable energy is 22% to 24%,


▽ nuclear power is 20% to 22%, and


▽ thermal power is about 56%


.



At the Climate Change Summit, Prime Minister Suga announced that he would aim to significantly raise the previous target and reduce it by 46% compared to 2013. A major overhaul of the power supply mix is ​​required to achieve the goal.



For this reason, the government is urgently considering expanding the introduction of renewable energy, gradually reducing old coal-fired power, and improving efficiency.



However, renewable energy has limited land suitable for power generation, and since the accident at TEPCO's Fukushima Daiichi nuclear power plant, safety concerns remain persistent among the people, so how to position nuclear power generation is also an issue.



The government will have to deal with difficult issues as to whether the goal can be achieved with little time left until 2030.

46% reduction

The Ministry of Economy, Trade and Industry and the Ministry of the Environment will continue to reduce emissions at the same pace every year from 2013 until 2050, which is the target year for reducing emissions to zero as a whole. It says that reduction is needed.



It also takes into consideration future trends in energy consumption such as electricity and heat, and reduction targets in other countries and regions.



While the reduction targets so far have been calculated by accumulating highly certain policies, the new targets have been made ambitious in line with the realization of a carbon-free society in 2050. , It is said that the meaning has changed from the past.



In addition, in order to achieve the target, it is necessary to further thoroughly save energy in industry and homes and expand the introduction of renewable energy, but there are no concrete numerical targets or plans at this time, and consideration will be accelerated in the future. And we are going to mobilize all the policies.
