|Total with reduced environmental impact||836||862||895|
Non-circulating vehicles being disposed of were not included.
The strategy of streamlining the use of the vehicles continued, beginning with the purchase of technologically advanced vehicles powered by fuels with reduced environmental impact to replace obsolete vehicles.
The Group owns 4,056 vehicles, of which 503 are methane powered, 373 are powered by LPG and 19 are electric, amounting to 22% of the total. In 2017, 266 vehicles were sold and/or scrapped, while 224 vehicles were registered, of which 150 diesel vehicles, 18 petrol vehicles, 36 methane vehicles, and 20 LPG vehicles. Currently, excluding AcegasApsAmga and Marche Multiservizi, the Hera Group uses 4 methane powered automatic waste compactors out of an overall total of 160.
The Group’s commitment to reducing the environmental impact of its fleet was further consolidated by the release, in 2013, of an operating instruction that prioritizes vehicles with reduced environmental impact (methane, LPG) when purchasing light commercial vehicles. Drafted in accordance with the principles laid down by EU legislation, the aim of this instruction is to reduce environmental impact through the identification of more environmentally friendly fuels and close attention to the different local contexts in which the vehicles have to be used. The benefits of the entry into force of the operating instruction are shown in the above table. In fact, the number of light commercial vehicles powered by low environmental impact fuel grew by 3.8% compared to 2016.
Also, in order to reduce consumption and improve safety on the waste collection vehicles, in 2013 Hera added the Drive System Tool (DST) device. The device is a measurement box that records the driving styles of drivers of side-loading waste compactors, and since 2015 has been standard equipment on all of Hera’s vehicles. It has helped to improve their mileage to 1.65 km/l, saving 514 toe in the three years since the device has been installed on our vehicles. A further reduction in the amount of repairs due to accidents and neglect was reported (-13% compared to 2013), following similar decreases in the previous years (-10% compared to 2015). The drop in fuel consumption also reduced environmental impact, given the lower amount of CO2 released into the atmosphere.
Furthermore, this new system:
- allows safer driving: waste collection vehicles in fact are subject to continuous stop-and-go driving under heavy load conditions;
- reduces maintenance costs, due to lower wear of the vehicles.
A comparison between the several types of fuel was made considering the primary energy present in the single fuels.
At Group level there was a reduction of 1.2% in fuel consumption. This decrease is distributed among the various fuel types but there was mainly a decrease in consumption of petrol (-14.6% compared to 2016) and methane (-13.4% compared to 2016), while consumption of LPG increased (+9.4% compared to 2016).
Despite the overall increase in vehicles with a low environmental impact, total fuel consumption is stable.
Comparing the total amount of fuel consumed by the Group’s vehicles to the total number of vehicles shows that the average consumption per vehicle decreased slightly in 2017, at 2.43 toe/vehicle.

|Consumption per vehicle (toe/vehicle)||2.38||2.42||2.43|
The average age of the Group’s fleet of vehicles is 7.5 years, while for Hera SpA, tit is 7.2 years, and continues to decrease compared to the 2013 when the value was 8 years. These results are the consequence of the investments made by the company, aimed at renewing its fleet of vehicles.
Hera’s commitment to sustainability and energy efficiency also has effects on the supply chain and in particular on the criteria used to choose suppliers. Given the high environmental impact of municipal sanitation services, especially in terms of atmospheric emissions, the Group has decided to reward the best-performing suppliers in this field, favouring those who use low environmental impact vehicles.
In 2017, excluding Marche Multiservizi waste management service providers used approximately 2200 vehicles for waste collection. Of these, over 11% has low environmental impact (4.9% use LPG, 4.7% use methane and 1.7% are electric) and over half are classified as Euro 5/6.
In 2017 actions continued to reduce the environmental impact of Group employee commutes. These included the continuation of the shuttle bus service in Bologna that connects Stazione Centrale (Central Station) with the offices in Viale Berti Pichat, Via Tdel Frullo/Via Cristina Campo and to the Imola Station to the offices in Via Molino Rosso e Via Casalegno. To encourage sustainable transport Hera has joined the Bella Mossa initiative, organized by the Municipality of Bologna, which aims to promote sustainable ways for workers to go to their workplaces, by rewarding those who travel on foot, by bike, by bus, by train or by car sharing and car pooling.
In 2017 the possibility of using pedal-assisted bicycles at the Viale Berti Pichat headquarters in Bologna was particularly successful and more than 200 staff members took advantage of special discounts on annual public transport passes, 50% for services managed by T-per and 45% for those of Trenitalia.
During the year, the Group joined to the participatory PUMS (Urban Sustainable Transport Plan) programmes of some cities in Emilia Romagna. These plans contribute significantly to achieving the climate and energy objectives set by the EU Member States, aimed at reducing greenhouse gas emissions by 40% by 2030.
In October, Hera participated in the “Climathon – sustainable transport” initiative, an event that aimed to reward the most innovative ideas on sustainable transport, to be implemented in the Ferrara area, among those proposed. There were over 40 participants of all ages and with different experiences, with a prevalence of university students from different faculties, including Engineering, Economics, Architecture, Medicine, Design, Computer Science, Communication.
Low environmental impact vehicles in the leading Italian utilities
According to a comparative analysis carried out among the leading Italian utilities by Utilitatis, Hera ranks fifth among the 16 Italian utilities considered, for the percentage of low environmental impact vehicles.
