But it's difficult to use them in old buildings and gas is said to be to most cleanest heating technology based on fossil fuels.

(Does that count as gaslighting? Sorry.)
So no, they don't want to label it green energy, they only prefer it to other fossil fuels and nuclear but the goal is to phase out natural gas as well.
Is the state-owned DW/ARD not a trustworthy news source?
So the news itself is correct but the headline abbreviates this very badly.
Even if every German building was using heat pumps, they would still be burning TONS of natural gas to keep the electricity flowing consistently, because they have no long term energy storage solution to pair with renewables, especially through the long, dark winters when the sun rarely shines.
It would be stupid to build storage there is not renewable generating capacity to charge. When there is such capacity, they will then build out storage. In the meantime the correct place to spend is on generation. Which, in fact, is what they are doing.
