We have the end of the "Gasspeicherumlage" tax in Germany, from 01.01.2026, the "Netzentgelte" might also fall away, and crude prices very low, so many people might actually see a drop in price.
Don't forget that CO₂ certificate prices are absolute numbers, so if they add €30, but the price falls by €40, then you have a €10 decrease.
