Direct and indirect greenhouse (GHG) emissions
Activities carried out to reduce the direct and indirect production of GHG
Within its organisation, Ansaldo STS has appointed a Carbon Manager, an Energy Manager and a Water Manager responsible for providing information and carrying out activities and projects with respect to energy savings at all the company’s operating sites.
Ansaldo STS’ initiatives to improve employee travel include optimising travel paths, using car pooling and car sharing and promoting the use of public transportation and more sustainable means through its travel policy.
One of the effects of the travel policy can be measured by the considerable reduction in shorthaul air travel.
Over the years, Ansaldo STS has implemented energy efficiency projects that have contributed to reducing energy consumption by nearly 20% in the period considered. Below are examples of steps taken by Ansaldo STS to reduce energy consumption:
- installation of energy-efficient lighting systems and the related electrical systems;
- increase in the energy efficiency of air conditioning and air treatment systems;
- elimination of or reduction in the use of transformers and air compressors;
- revision of the automated building management system to delay when the lighting system and air conditioning turns on in the morning and anticipate it in the evening;
- improvement in the datacenter’s energy efficiency;
- affixing of signs to remind personnel about energy saving projects, such as turning off lights, laptop computers and devices that consume energy;
- reduction in the number of vehicles used by the company;
- reduction in the total volume of waste sent to landfills by encouraging the use of low impact substances and promoting the reduction, recovery and recycling of waste.
Overall, production has gone from 25,489 tonnes of CO2e to 19,142 tonnes of CO2 e in the period from 2012 to 2014, a reduction of 6,347 tonnes of CO2e (-24.9%).
The following graph shows the GHG Emission Intensity indicator, which measures the tonnes of GHG emissions by each €1 million of turnover.
The total (direct and indirect) emissions indicator shows a reduction (-6-3%) due to both the decrease in emissions and a rise in turnover. This reduction is even more marked compared to 2012 (-28.1%). This consideration is also true of the partial scope indicators. Indeed:
- the Scope 1 emissions (direct combustion of fossil fuels from the organisation’s sources) indicator is -2.7%;
- the Scope 2 emissions (generation of electrical energy used by the organisation) indicator is -5.7%;
- the Scope 3 emissions (from sources not owned by the organisation, mainly due to the transport of people and goods, consumption of raw materials and elimination of waste) indicator is -8.0%.
