2,451,198 TOE CO2 avoided

In 2018, renewable sources, cogeneration, separated waste collection and specific projects have made it possible for Iren Group to reduce emissions by over 2.4 million tonnes of CO2.

The generation of electricity from renewable sources creates significant positive effects on the reduction of emissions; moreover, the predominant cogeneration framework (production of electricity and thermal energy that feeds the district heating networks in different cities) of the Group’s thermoelectric plants significantly contributes to containing specific greenhouse gas emissions.
In order to reduce pollution, only natural gas is used to supply the energy production plants and both low emission combustion systems and pollutant reduction systems are installed (catalysts for the reduction of CO and NOX).
Continuous emission monitoring systems make it possible to detect in real time the main pollutants and the improvement of the efficiency of the combustion process of cogeneration plants, larger thermal plants and waste-to-energy plants. The latter are also required, pursuant to the relevant Integrated Environmental Authorisations (IEA), to comply with stricter emission limits than those contained in national legislation.
The combustion of the biogas produced in landfills produces the maximum reduction of methane and any other greenhouse gas emissions. 


The excellent results achieved in terms of decarbonisation are partly recognised by the 2018 Carbon Disclosure Project, which awarded Iren an A- evaluation, the only multi-utility out of the top ten Italian companies ranked.
