And this residential burning emits high levels of particulate matter and
it is out of control.
There's no strict regulation,
there is actually almost no regulation of residential burning.
And here we need on the city level, either to introduce low emission zones
restricting residential burning in residential areas.
For example, forbidding wood burning, where you have gas and district heating.
Or you would start to tax residential burning and
thereby make it unattractive to use residential burning,
in areas where low pollution gas or district heating.
So even on a municipal level, you need management,
you need regulation of problems that might seem small, but in Denmark,
residential wood burning actually emits 70% of the total particle pollution.
Traffic only emits about 15%.
So residential burning is a huge issue, not only in developing areas, but
in developed countries as well.
Another sector is farming.
Farming emits a huge amount of ammonia.
Ammonia is not really toxic in itself, but in the atmosphere,
it leads to the formation of a particulate matter.
And thereby contributing significantly to mortality and mobility in the population.
