@lwhemmings @JurajMikurcik Re ‘greenest’ a major contribution has to be the carbon stored by the product. This makes wood fibre insulation ‘greener’ than any mineral wool or polystyrene or sheep’s wool. Sheep’s wool will have a relatively low embodied carbon, probably lower than wood fibre. Consult EPDs?
