The total support for coal related to general services in Japan shows a slightly downwards trend from 2024 to 2028, with projected values of $20.66 million in 2024 to $20.51 million in 2028. As of 2023, the support level stood at $20.71 million. The slow decline in the support level from 2024 onwards suggests an average annual decrease—CAGR—over this forecast period, which indicates slight but consistent reductions.

Future trends to watch for:

Shifts in energy policy towards renewable energies which might further reduce coal support.
Technological advancements in cleaner coal technologies could offset some of the decline.
Global market trends influencing energy import costs could alter domestic support dynamics.
