Metal emissions

We monitor and take steps to reduce the impact of metals emissions on the environment – both to water and air. Each of the different metals that we emit has a specific level of potential toxicity for the environment and human health. For this reason, we focus on reducing the impact of our emissions.

Group data – emission scope metal emissions to air and water

The aim for Horizon 2020 was to reduce metal emissions impacts while considering growing volumes of production. While monitoring continues on all sites, reporting focuses on the 10 or fewer sites that contribute to 95% of the emissions expressed in impact.

In 2020, the impact of metal emissions to air fell by 67% compared to 2015, mainly thanks to further efforts to improve filtration and process efficiency. Compared to 2015, after correction for activity levels, the impact of metal emissions to water in 2020 fell by 59%.
