Air Quality Protection

The increased percentage of natural gas in the mix of used fuels, as well as the adoption of the best technologies in all the business sectors, have contributed to reduce the release of substances that are harmful to the atmosphere.

In 2009, in addition to the reduction in the emissions of CO2, the emissions of NOx overall have also decreased (-2.8% compared with 2008). In particular the electrical sector registered a significant decrease (-11%) compared with 2008. Also the SO2 emissions have shown a trend of decrease over the years (-5.2% average, -34.3% in the G&P sector) in all sectors, following the use of low-sulphur fuels or with the sulphur entirely replaced by natural gas.
