And its models say that traffic diversion will increase levels of PM10, particulate matter with a diameter of 10 microns or less that harms the hugs and heart and is commonly emitted from vehicles and construction sites.

Although carbon dioxide is the most prevalent and potent greenhouse gas, it is not the only major one — and many of its companions are also being emitted at unprecedented rates.

The carbon emitted has only recently been removed, either by plants or by chemical processes.

Cosentino said it had commissioned research from the Instituto de Tecnologia Ceramica in Spain, which found one of its “low silica” slabs emitted less crystalline silica than natural granite and had similar amounts of metals such as aluminum and tin.

These controls restrict the levels of gases such as carbon dioxide that can be emitted.
