Aerosoler 10
Set 3 www.climatefresk.org 10 Klimatmässigt har detta inget att göra med sprayflaskor. Aerosoler är en form av lokal förorening som uppkommer vid ofullständig förbränning av fossila bränslen. De har skadlig inverkan på mänsklig hälsa och bidrar negativt till strålningsdrivningen, vilket leder till ett svalare klimat.

Although aerosols are not alone in the "fine particle" category, every year 391,000 people in EU countries die from air pollution, and it causes 1.1 million premature deaths in India and China. Air pollution such as soot caused by the burning of fossil fuels such as coal and oil was responsible for 8.7m deaths globally in 2018.

Other possible causes

Buildings emit few aerosols directly. The only significant emissions are chimney fires. In Chamonix, 85% of the fine particles present in the atmosphere come from wood heating.
Transport

Transport

Local pollution due to exhausts pipes is one of the main motivations to promote electric cars, far more than climate change. But EV are responsible for CO2 emissions due to power generation. These emissions depend a lot on the country where the car is rolling. See the file about it.
Jordbruk

Spraying crops does result in aerosols and air pollution, but not to the same extent as incomplete combustion from power plants.

Smoke from wildfires has been shown to carry toxic particles.
