1. 2016 emissions data for NOx, SO2 and CO (like those of 2015) have been estimated based on the consumption of natural gas and diesel to produce thermal energy by using the rates obtained through an analysis of 2014 data.

2. Estimated on the basis of 2014 data and the ratio of hours worked in 2016 compared to the hours worked in 2014 at the Tito Scalo site (1.026).

Atmospheric emissions mainly relate to the production sites and only some of the office sites (Les Ulis – France, Pittsburgh – US, Naples and Piossasco – Italy).

In 2016, there was an increase in atmospheric emissions at production sites due to higher consumption of natural gas as thermal plants were working, in contrast to other sites where a decrease was recorded.

The Tito Scalo site monitors emissions of volatile organic compounds, volatile inorganic compounds and heavy metals derived from their production processes. CO and NOx emissions mainly derive from thermal energy plants equipped with effective filters to reduce pollutants.

Data on particulates relate to the Tito Scalo site and concern emissions from the production and handling of goods.
