|Total with lower environmental impact||862||895||922|
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 4,044 vehicles, of which 496 are methane powered, 404 are powered by LPG and 22 are electric, amounting to 22.8% of the total. In 2018, 347 vehicles were sold and/or scrapped, while 238 vehicles were registered, of which 178 diesel vehicles, 12 petrol vehicles, 26 methane vehicles, 18 LPG vehicles and 4 electric vehicles.
Currently, excluding AcegasApsAmga and Marche Multiservizi, the Hera Group has 2,715 vehicles, of which 419 are natural gas powered, 402 are powered by LPG and 9 are electric, amounting to 31% of the total. In 2018, 165 vehicles were sold and/or scrapped, while 143 vehicles were registered, of which 21 used natural gas, 18 used LPG and 1 was electric, amounting to 28% of the total quantity of vehicles purchased. Currently, excluding AcegasApsAmga and Marche Multiservizi, the Hera Group uses 2 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 operating guidelines that prioritize vehicles with lower environmental impact (methane, LPG) when purchasing light commercial vehicles. Prepared in accordance with the principles set by EU legislation, the aim of the guidelines is to reduce environmental impact by identifying more environmentally-friendly fuels and paying 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. At Hera Group level, in fact, the number of light vehicles powered by low environmental impact fuel increased further in 2018: by 3% over 2017.
Also, in order to reduce consumption and improve safety on the waste collection vehicles, in 2013 Hera added the Drive System Tool (DST) device. Fully operational since 2015 on all vehicles, the device uses a measurement box to record the driving style of the drivers of side-loading waste collection compactors. This measurement allowed consumption to settle at around 1.65 km/l (2018), generating a reduction of 276 toe between 2017 and 2018. The drop in fuel consumption also reduced environmental impact, given the lower amount of CO2 released into the atmosphere.
A comparison between the several types of fuel was made considering the primary energy present in the single fuels.
The consumption of fuel consumed by the vehicles remains stable. Diesel consumption is in line with 2017, while gasoline and LPG consumption are up, by 2.6% and 2.1% respectively. Methane consumption decreased by 3.5%. Overall, the consumption of fuels with a reduced environmental impact decreased by 1%, mainly due to the reduction in kilometers traveled.
|Consumption per vehicle (toe/vehicle)||2.42||2.43||2,45|
The average age of the Group’s fleet in 2018 is 7.9 years. For Hera SpA, instead, it is 7.18 years, slightly down compared to 2017 and continues to decrease compared to 2013, when it was 8 years. These results are the fruit of the company’s investments to renew its vehicle fleet.
Low environmental impact vehicles in the leading Italian utilities
According to a comparative analysis carried out by Utilitatis among the leading Italian utilities, Hera ranks third among the 17 Italian utilities considered, as to percentage of low environmental impact vehicles. In 2018 Utilitalia published its first sustainability report that summarizes the environmental performance of 127 Italian utility companies: the Hera’s result (22.1%) for the 2017 is 84% higher than the average of the utilities considered (12.0%).

Hera’s commitment to sustainability and energy efficiency also affects the supply chain and in particular the criteria used to choose suppliers. Given the high environmental impact of waste management, 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 2018, excluding Marche Multiservizi, waste management service providers used approximately 2,400 vehicles for waste collection. Of these, 12% has low environmental impact (6% use LPG, 5% use methane and 1% is electric) and over 60% is classified Euro 5/6. In 2018, the number of vehicles in the Euro 6 emissions stage increased by 215; these vehicles partly replaced vehicles with greater environmental impact and partly were additional compared to 2017. There was also an increase in light vehicles (+296 units) at the expense of heavy vehicles (-95 units) due to the increase in home collection services provided by suppliers.
