750 HGV's in Your Lounge?

Microparticles of carbon (so-called PM2.5's, based on their size), once breathed in, can enter the bloodstream and pass into body organs. Annually, PM2.5's have been estimated to cause 40,000 early deaths in Europe. The public health focus has been on 'air pollution' and the microparticle emissions from diesel-fuelled vehicles. Rather obviously, Heavy Goods Vehicles (HGVs or 'trucks') produce many more PM2.5's than smaller cars. PM2.5's are, however, also produced by wood-burning stoves and new regulations for these devices are coming in in 2022 (https://www.theguardian.com/environment/2021/oct/09/eco-wood-stoves-emit-pollution-hgv-ecodesign). Wood-burning stoves are popular in some circles, where they are viewed as a cosy 'traditional' source of heat. From 2022, it will only be legal to sell Ecodesign wood-burning stoves in the EU and the UK. The Ecodesign standard is marketed as being 'ecofriendly'. One Ecodesign stove, however, produces as many PM2.5's as 750 HGV's. This is far from 'ecofriendly'. Experts have described the stove's specifications as being 'shockingly weak'. It would be like having the trucks in a large commercial carpark, continuously revving up in your house! In the UK, domestic wood burning is the biggest source of PM2.5's but little seems to be done about this source of air pollution.
