The G7 Climate, Energy and Environment Ministers' Meeting was held in Sapporo. The joint statement released on April 16 called for additional measures to reduce domestic greenhouse gas emissions and introduce renewable energy.

Joint statement to introduce 1000 GW of solar power in 7 countries in 2030

The three important quantitative targets on climate change specified in this joint statement are: The provisional translation of that part is excerpted as follows: (1) It is becoming increasingly urgent to reduce global greenhouse gas emissions by approximately 43% by 2030 and by 60% by 2035 compared to 2019 levels. (2) achieve complete or largely decarbonized power sector by 2035; 150 GW) and increasing renewables capacity through existing national targets and policy instruments to a total of more than 1 billion kW (1000 GW/1 TW) by 2030. Contribute to cost reduction.
Of these, the reduction level of greenhouse gases differs from the domestic target in terms of the base year, and the current Basic Energy Plan sets a 46% reduction by 2030 compared to 2013 levels. Compared to the G7 target of 2019, this is less than a 40% reduction, so a reduction of 20 points or more will be necessary in just five years from 2030. In the future, it is likely that the setting of a "reduction target for 2040" will be discussed in Japan as well, but there is no doubt that the "reduction of 60% compared to 2019 by 2035" will have a significant impact. seems to be required.
The goal of "completely decarbonizing the power sector by 2035" was included in last year's G7 joint statement, but was emphasized again. In the Basic Energy Plan in Japan, in FY2030, "36-38% renewable energy", "20-22% nuclear power", and "1% hydrogen/ammonia", for a total of 57-61% decarbonized power sources. In addition, as a reference value for 2050, the power source composition is shown as "50% to 60% renewable energy", "30% to 40% nuclear power and thermal power with CCS (CO2 capture and storage)", and "10% hydrogen and ammonia".
In order to be able to say "completely or largely decarbonized" by 2035, it seems essential to accumulate renewable energy as early as possible after 2030 and aim for "40% to 50%" as the next stage.
The epoch-making point of the G7 joint statement this time is the setting of quantitative introduction targets for "solar power" and "offshore wind power" among decarbonized power sources. This means that these two decarbonized power sources share the common recognition that the development potential of these two decarbonized power sources is extremely large, and that they are becoming economically viable as costs are being reduced. .
The target of 150 GW (150 GW) of offshore wind power generation and 1 billion kW (1000 GW/1 TW) of solar power generation in the seven countries by 2030 means that the offshore wind power generation capacity will increase by 7% compared to the current installed capacity of the seven countries. It is said that the amount of sunlight will triple. In Japan, offshore wind power is currently the first full-scale offshore wind power project in Japan, with a capacity of 140 MW, which has just started operation off the coast of Noshiro City in Akita Prefecture. You are required to go.
On the other hand, regarding the domestic target for solar power, it is assumed that the current installed capacity of about 60 GW will be doubled to about 120 GW in 2030. The target value of the G7 this time is not a target for each of the seven countries, so it is not necessarily required to "triple", but as long as the overall target is "more than 1,000 GW with a threefold increase", at least The current domestic target of 120 GW is unavoidably achieved, and further increases are required. While even achieving 120 GW is in doubt, more effective promotion measures are likely to be discussed.
