No hard facts, and only a passing mention that hints that the worst polluters are open fires.
Nothing about solid fuel central heating which generally uses anthracite beans.
Nothing about (for example) garden bonfires.
Previous articles have let slip that the issues are often about running wood burners with the fire doors open, and that they are not such a problem with the doors closed.
Our wood burner is for pleasure and also as a backup heat source. Cooking at a pinch.
The electricity here is pretty reliable, but I still recall a couple of houses back when we were the only house able to cook because of our solid fuel Rayburn when the power went out for an extended period. So having an alternative is reassuring.
Anyway, Happy New Year.
