And net 0 can include petrochemicals.

Maybe at some point in the future when carbon capture is a viable technology. But we're already at the point where "we'll deal with it later" is not a good enough solution.

I agree that there's no way around petrochemicals, and we'll have to offset the emissions to reach net 0.

Gas heating has an alternative though. Heat pumps are already cheaper to run compared to gas heating, even without any carbon offsetting.

The pressure to reach net 0 is only gonna grow as the impacts of climate change get worse. To reach net 0 we'll have to offset all significant emissions. When the offsets are priced in, using gas heaters becomes insanely expensive in comparison to heat pumps.

It's just a matter of time until gas heating is essentially dead. It might be in 10 years or 20 years, but there's no way around it.
