The government's Council of Experts has put together a countermeasure plan that includes the aim of introducing solar power generation equipment into 60% of newly built single-family homes as of 2030 toward the realization of a carbon-free society.
The government has set a goal of reducing greenhouse gas emissions by 46% toward 2030 compared to 2013, but the amount of carbon dioxide emitted from buildings such as houses and buildings is the same for Japan as a whole. It accounts for more than 30% of emissions, and energy saving in housing is an issue.
Regarding this, the Council of Experts established by the Ministry of Land, Infrastructure, Transport and Tourism summarized the proposals for energy conservation measures for housing, etc. at the meeting on the 10th.
According to this, newly built single-family homes will be obliged to comply with the current energy-saving standards in 2025, and from 2030 onward, they will be obliged to comply with the standards that further reduce energy consumption by 20% from the current standards. It is said.
On top of that, as of 2030, we aim to introduce solar power generation equipment in 60% of new homes.
Experts have also commented that the installation of solar panels in homes should be obligatory, but caution is given that there are differences in the amount of power generation depending on conditions such as location and that the burden on individuals should be taken into consideration. In this countermeasure plan, the expression was limited to "considering future obligations as an option."
The Ministry of Land, Infrastructure, Transport and Tourism will review the necessary systems and consider specific measures in the future.
