MoE Policy to Include Priority Support Models, More Perovskite Solar and Hourly Energy Management

The Ministry of the Environment (MoE) has outlined its future policy direction for leading decarbonization regions – which aim to achieve net-zero CO2 emissions from electricity consumption by FY 2030. Based on progress and challenges identified so far, the ministry has defined three priority support models:(1) disaster prevention and resilience enhancement, (2) use of domestic resources, and (3) regional economic revitalization. Projects would be developed under one of these models.

The previous framework for the leading decarbonization regions was based on open-ended proposals, which some stakeholders saw as a high barrier to application. By categorizing the initiatives into three models and deploying them across regions, the MoE aims to attract more capital and create a more resilient energy system that maximizes regional resource potential.

The ministry will also promote the following specific policies in the leading decarbonization regions:

Deployment and utilization of perovskite solar cells
Introduction of advanced energy management systems that track supply and demand on an hourly basis
Technical support for local production and consumption of renewable energy
Establishment of regional energy companies and clarification of their roles
Stronger collaboration among relevant regional stakeholders, including local governments, businesses, and financial institutions

Ahead of its FY 2027 budget request, the MoE will finalize specific program details this summer, including subsidy rates and eligibility requirements. While continuing support for existing leading decarbonization regions, the ministry aims to shift regional decarbonization toward the implementation phase, centered on the new models.

🔍 Shulman Commentary:

As of February 2026, the Japanese government had selected 102 proposals for decarbonization regions, covering 133 municipalities across 45 prefectures, achieving its initial target of at least 100 regions. The introduction of three new models suggests that policy support is now shifting to reinforcing the implementation. While this could open wider business opportunities both for local stakeholders and companies offering advanced technologies and know-how, outsiders should be aware of diverse regional geographic and regulatory conditions.
