JP GX Promotion Act (Act on Promotion of a Smooth Transition to a Decarbonized Growth-Oriented Economic Structure)
ENFORCEMENT TIMELINE
Enacted May 2023, taking effect in stages (carbon surcharge from fiscal 2028; paid allocations for the power generation sector from fiscal 2033)
Overview
The Act on Promotion of a Smooth Transition to a Decarbonized Growth-Oriented Economic Structure (GX Promotion Act) is the basic framework law for mobilizing more than 150 trillion yen in public and private green transformation (GX) investment over the next decade, aimed at achieving carbon neutrality by 2050 while strengthening industrial competitiveness. It establishes advance investment support through the issuance of GX Economic Transition Bonds, a "growth-oriented carbon pricing" concept combining a carbon surcharge on fossil fuels (from fiscal 2028) and a levy on specified business operators through paid allocations under the GX Emissions Trading Scheme (GX-ETS, from fiscal 2033) in the power generation sector, and the establishment of the GX Promotion Agency.
Enforcement Timeline
May 2023: The GX Promotion Act is enacted and promulgated.
June 2023: The act partially takes effect, including formulation of the basic policy.
July 2024: The GX Promotion Agency (Organization for the Promotion of a Smooth Transition to a Decarbonized Growth-Oriented Economic Structure) is established and begins operations.
Fiscal 2026: The GX-ETS emissions trading scheme becomes fully operational, including mandatory target-setting.
Fiscal 2028: The carbon surcharge on fossil fuel importers and other businesses begins.
Fiscal 2033: The levy on specified business operators (paid allocation) for power generators begins.
Business Impact
Fossil fuel importers and energy-intensive manufacturers need to undertake structural business reforms to prepare for rising medium- to long-term carbon costs, including the surcharge that takes effect from 2028 onward. At the same time, the large-scale government support for research, development, and capital investment provided through GX Economic Transition Bonds, covering areas such as hydrogen and ammonia, next-generation innovative reactors, and storage batteries, is expected to create opportunities for new business creation and the implementation of decarbonization technologies.
