The total energy produced from renewable sources in 2017 came to 30.3%, higher than 2016 with regard to thermal energy as reported above. The share of energy produced from cogeneration and turboexpanders is equal to 37.5%. Together, the two categories represent 67.5% of total energy produced by the Group.
In coming years, there will be a further improvement in the Group’s energy production sustainability profile, mainly due to:
- The start of construction in 2018 of an already mentioned plant to produce biomethane from organic waste, in Bologna;
- 8% increase within 2021 in the use of geothermal energy for the district heating system in Ferrara;
- increase by 23% by 2021 the carbon footprint of electricity production from landfill biogas (new plants);
Below is an outline of the environmental performance of the district heating projects financed or refinanced through the Green Bond issued in July 2014.
