Union faction vice-chair Sepp Müller stated: "We will let the fuel discount expire as planned on June 30th." Fiscal cost was cited at approximately EUR1.6 billion over two months. - The Monopolkommission and BMF have both published monitoring data confirming the 14.04 ct/L tax cut has been largely passed through; filling up before June 30 avoids the full reversal. ## Attribution Tank Alert aggregates the Tankerkönig CC-BY 4.0 dataset.
