Efficiency and the environment
Efficiency and the environment
We carry out our activities with full respect for the environment, taking care to manage energy and natural resources efficiently.
We will reduce our greenhouse gas emissions by 30% and our energy consumption by 25% by 2027.
Both compared to 2020 (baseline), on a like-for-like scope (excluding any changes following M&A and ATEM tenders).
Inorder to achieve these objectives integrated in our business plan, our digital skills and tools, such as Picarro, and the know-how of Seaside, the Group’s ESCo, specialised in energy efficiency,play a key role.
To guarantee our commitments and objectives, we have developed the Group HSEQE Policy, and we have the most advanced management systems, certified according to international standards, for health, safety, environment and energy efficiency aspects.
With innovative technologies and our technical expertise in the field of energy, we generate value for the territory and manage energy and natural resources efficiently, limiting the environmental impact of our infrastructures and taking care of people.
Sustainability Highlights 2020
These results derive from relationships of trust and transparency with our main stakeholders on the ground:
- People involved in our day-to-day operations.
- Authorities and institutions with partnerships and projects.
Through these synergies, we combine our responsible approach with our ability to generate research and technological innovation with the goals of improving energy efficiency, reducing our carbon footprint and managing resources efficiently.
Increasing our energy production from photovoltaic systems
To further reduce fugitive emissions*, we are taking steps to make the network more sustainable by replacing cast iron pipes with lead hemp joints, in favour of steel and polyethylene, which not only increases safety levels but also helps reduce gas releases into the atmosphere.
* Given its operation as a DSO and given that Italgas does not own transportation or storage assets, fugitive leaks are the only relevant type of gas leakages (vent leaks have a residual significance, while pneumatic and unburnt are not present).
The increase in direct Scope 1 emissions in 2020, resulting from the expansion of the scope of activities. Indirect Scope 2 emissions in 2020 decreased by 97% compared to 2019 as a result of purchasing electricity produced from certified renewable sources, as certified by the Guarantees of Origin (GO) management system. Scope 3 emissions are slightly up insofar as the Group scope has increased on 2019. Scope 3 emissions from outsourced activities, calculated by associating a factor to convert the value of expenditure into CO2 emissions for each product class, increased as a result of a 16% increase in expenditure.
Our energy efficiency
Energy is mainly used in Italgas for industrial purposes. Natural gas is the most widely used energy source, followed by electricity and natural gas for transport. In 2020, energy consumption was 592.15 TJ. The figure shows a slight increase compared to 2019 due to the fact that Toscana Energia is included in the consolidation for the full year 2020, whereas in 2019 only the last 3 months were consolidated. There has been an increase in the consumption of natural gas for transport and a significant reduction in the consumption of diesel and petrol due to the use of natural gas hybrid cars. Medea’s consumption increased as the company expanded its perimeter by acquiring the company Isgas.
Applying a new methodology to monitor and reduce gas emissions, thanks to Picarro
We have defined a new methodology for calculating emissions from fugitive natural gas leaks, based on data collected using Picarro Cavity Ring-Down Spectroscopy (CRDS) technology . The technology is 1000 times more sensitive than traditional technology and we can apply a more rigorous and precise calculationto provide us with more robust data.
The method is based on the determination of the magnitude of individual fugitive gas emissions, which are derived from big data analyses collected from planned leakage searches performed along the networks using Picarro technology.
The accuracy of the method
The accuracy of the method is guaranteed by the possibility of:
- Classify and accurately locate both the most significant and influential gas emission sources (super emittersas well as smaller ones).
- Quantify the expected benefits/improvements from targeted maintenance initiatives on the network.
- Prioritise network renewal interventions with a view to reducing the effects of gas leakage and an appropriate cost/benefit balance.
To calculate the emissions, the figure obtained with this method for methane (CH4) is reparameterized to natural gas, increasing it by 9%, as the natural gas distributed in Italy contains on average 91% methane (CH4).
In order to obtain as complete a value as possible, leaks reported by third parties were also taken into account, taking into account the average daily volume of leaks identified by the CRDS method and a maximum repair time of 48 hours.
We manage resources responsibly
We handle materials and waste in a sustainable and responsible way. In managing our activities, our most important impact concerns:
- Remediation, environmental restoration and monitoring of brownfield sites.
- Over the next two years, virtuous disposal activities of mechanical meters replaced by smart meters. Inthe long term, over the next five years we will develop the most useful and sustainable approach to the end-of-life management of the smart meters themselves.
Our plastic-free offices
To reduce our impact in terms of plastic consumption, we distributed more than 4,000 eco-friendly bottles made of metal and other recycled materials to all employees.
Our initiative is part of a wider plastic reduction programme, with water dispensers being installed at all sites to replace plastic cups and scoops. We did this by joining the Water Will Save The Waterproject, with which, for every water bottle purchased, we helped remove over 1 kilo of waste from the Mediterranean Sea and the Italian coast.
The methanisation of the country as an opportunity for sustainable development
During 2020, the plan to convert the distribution networks currently operated on LPG to natural gas continued. A total of 22 locations were in fact converted (in 13 different municipalities nationwide), which were originally powered by LPG and now have new distribution systems for the supply of methane. The work involved extending the network by a total of 152 km.
Our 100% green fleet
Our company vehicle fleet is 100% natural gas-powered. In addition, in order to enable all our people to use their cars efficiently, we have installed the appropriate charging stations at the operational sites.
