The measurement of the environmental investments makes it possible to quantify in economic terms the measures carried out in order to improve the environmental sustainability of the Group and the territory in which it operates, thereby showing how much of the activity translates into environmental improvement.
Any investment connected to measures which resulted in a significant environmental benefit was defined as an environmental investment. Taking account of the activities operated by Hera, several characteristic activities carried out by the company such as separate waste collection, the operation of composting plants or the expansion of treatment plants were also taken into consideration.
Recognition of these investments was carried out for the following companies: Hera Spa, Herambiente, Hera Comm, Uniflotte, AcegasApsAmga, Hera Luce and Marche Multiservizi.
|in millioni of Euro||2015||2016||2017|
|Integrated water service||106.5||107.3||111.0|
|Waste management services||17.2||22.9||35.3|
The data applies to AcegasApsAmga, Hera Spa, Herambiente, Hera Comm, Hera Luce, Marche Multiservizi and Uniflotte.
With regard to investments, in relation to energy services, the activities considered were those aimed at the extraordinary maintenance of the gas networks, the construction or upkeep of plants for the generation of electricity from renewable sources or similar sources and the management of district heating systems. The investments related to industrial cogeneration and the energy efficiency measures in the public lighting area made by Hera Luce were also considered.
For the water service, the interventions aimed at reducing losses within the water networks, the extensions of the sewage network and treatment plants and the interventions to improve the environmental performance of the plants themselves were counted.
For the waste management services, the activities related to separate waste collection, e.g. investments in equipped drop-off points, the construction or upkeep of the waste selection, separation and composting and biomethane production plants, the reduction of atmospheric emissions from waste-to-energy plants, and the generation of electricity in waste-to-energy plants were considered. Also considered were the investments for the disposal of waste produced by the company (e.g. landfill leachate collection facilities in landfills) and separate waste collection containers.
With regard to the central structure, investments for the purchase of vehicles with a lower environmental impact (methane, LPG, etc.) and of skips and “igloo” bins for separate waste collection were considered.
Total environmental investments amounted to Euro 232.3 million, up by 11% with compared to 2016 and amounting to around Euro 23 million more. This change was made up as follows:
- increase in investments in the energy services (+10% compared to last year corresponding to around Euro 7.6 million) in particular on the gas networks and plants and energy efficiency measures on public lighting systems;
- investments in water services increased (+4% compared to last year reaching around Euro 4 million), in particular for investments in improvements to the water and sewerage network;
- investments in waste management services increased (+54% compared to last year, i.e. around Euro 12.4 million), mainly due to the investment in the biomethane plant at Sant’Agata Bolognese;
Environmental investments accounted for 53% of non-financial operating investments.
