産業競争力の強化の機会・エネルギー安全保障の向上・経済成長の促進：日本の第2次NDC

The report assesses Japan's second NDC, which targets a 60% reduction in greenhouse gas (GHG) emissions by 2035 and 73% by 2040 compared to 2013 levels. The authors argue these targets are insufficient compared to the global average required to limit warming to 1.5°C and risk Japan losing market share in the global clean energy transition. Key recommendations include accelerating the deployment of solar and wind power, implementing a more effective carbon pricing mechanism with a binding cap, and establishing a clear roadmap for the phase-out of coal-fired power plants.

• There is a significant gap between current policies and the 2030 target; based on 'measures with' scenarios, Japan is projected to reach only a 42% to 46% reduction by 2030, missing the 46-50% target.
• The current GX Emissions Trading Scheme (GX-ETS) lacks a binding emission cap and a sufficiently high carbon price; the report suggests a price of approximately 140 USD per tonne of CO2 by 2030 to align with international standards and avoid EU CBAM costs.
