As of 2024, France's forecasted tax expenditure on coal for electricity generation is projected to rise steadily from 49.17 million USD to 61.46 million USD by 2028. This represents a consistent upward trend post-2023, where the bases for comparison would have been set. The year-on-year growth rate from 2024 to 2028 averages around 5.65%, indicating a significant escalation in tax expenditure due to various economic or policy factors surrounding coal energy reliance.

Future trends to watch for in French energy policy may include:

A shift towards renewable energy sources which could alter the trajectory of tax expenditures on coal.
Impacts of international climate agreements and domestic policies aimed at reducing carbon emissions.
Technological advancements aiding a decrease in coal dependency, potentially impacting future tax expenditures.
