Not completely. If the wood is from renewable sources, the carbon usage is low, because it gets recaptured when they grow the next batch. Net carbon usage is from transport and logging. As such it's much better than fossil fuels.

It does contribute to air pollution, but that's more of a problem in a city, where it's diluted over a smaller area.

I did once look into whether it would be possible to run a carbon negative BBQ by doing wood pyrolysis of renewable wood and ending up with black carbon to bury. It does seem possible, but still has the air quality issue. And there's a risk that you'd emit some methane (if you fail to burn it), which would be bad. Also, I wasn't sure how to figure out whether it would emit more CO than a normal BBQ. In theory that would be the best case for carbon though.

(You'd need "showdead=yes" to see most of their comment history).

If anyone was curious. Well insulated pizza oven needs surprisingly little wood. It takes some to put it in the right tempature but then it just needs piece here and there to retain it. It will stay hot for hours afterwards so many people afterthey are done with pizza use it for slow cooking, pulled meats and broths. Often you can even make breakfast eggs next morning.

yes, any time you're burning wood you're climate unfriendly. But a lot of other things are climate unfriendly: where do you live what's the energy source breakdown? It's all renewable? Your computer was manufactured and furnaces were involved at some point: what about their emission? It's CO2 all the way down.

You should look at all of this relatively: from an absolute standpoint, humanity isn't good for the planet

It's a pizza, bud.

No, actually! Not at all!

Driving to a restaurant is, though

Technically: Yes. A modern natural gas stove would be more efficient.

Practically: No. It's just not enough emissions to worry about.

The climate aspect isn't much of a problem due to scale.

The problem rather is local pollutant emission, particularly when the wood used isn't completely dry.
