Other data regarding safety, chain responsibility and the environment

Keep promoting safety awareness

Our aim is to prevent any safety incident from occurring during our activities. We therefore apply strict rules on working safely and responsibly. We pay great attention to safety awareness to ensure that our employees apply these rules correctly. We have drawn up a top 10 of the most common risks involved in our activities and have indicated for each of these risks how they can best be avoided. These are our Golden Rules of Safety, which should always be observed during our activities and operations. These rules are available in Dutch, German, English, French, Italian, Spanish and Polish. The rules contribute to raising risk and safety awareness in order to prevent unsafe situations. They make it very clear that there are certain lines that may never be crossed.
The Site Safety Instructions Golden Rules of Safety e-learning module for third-party employees was entirely updated in the year under review. Our own employees have access to both the training programme and e-learning module in our own learning environment.

Prevention is better than cure

We take a proactive approach to preventing accidents at work, with regard to both our own employees and employees of third parties. Everyone who works for us is obliged to comply with the laws and regulations and our own additional requirements. Moreover, when accidents, incidents and dangerous situations are reported, we determine what measures need to be taken to prevent such incidents from happening in the future. The Safe@Gasunie Experience inspired us to research whether incident investigation based on the safety buffer from the Experience contributes to a better analysis and supported improvement measures from an incident investigation.
We devote considerable attention to creating a healthy and safe working environment, both in our offices and in the field. Our manuals include rules and procedures for this purpose, from rules relating to ergonomic workstations for office staff to the conduct of employees working in the field.
Since we want our employees to be safe not only when they are on our premises, but also when they are on the move, we have included a blanket ban on making phone calls (even ‘hands-free’) while driving. This rule may only be overridden in dire emergencies.

Hazard identification and risk assessment

The basis for all measures that we take to ensure employees can work safely and in good health is contained in the hazard identification and risk assessment. The hazard identification and risk assessment was entirely updated this year. We took stock by visiting locations throughout the country and interviewing employees there. The plan of action ensuing from the hazard identification and risk assessment contains numerous new activities for the coming years aimed at ensuring that any areas where residual risks are still (too) high or can be further reduced are tackled. The health and safety officer will report to the management and the Works Council on the implementation of the plan of action.

Incidents in 2017

In 2017, the number of reportable incidents decreased to 16 (2016: 19). More information on this is given in the Safety results section. The table below shows the total number of incidents that occurred involving Gasunie employees, including incidents involving contractors’ employees while carrying out work for Gasunie.

European benchmark for pipeline incidents (EGIG)

European gas transport companies register their pipeline incidents in the same way, allowing their performance to be mutually comparable. Registration takes place within the European Gas Pipeline Incident Data Group (EGIG), which registers both pipeline lengths and pipeline incidents with gas leaks. This data is used to determine the ‘failure frequency’. This is the frequency (per 1,000km per year) of pipeline incidents with gas leaks due to, for instance, excavation activities, corrosion, construction defects and material defects. With regard to pipeline incidents with gas leaks, we score slightly better than the European average. In the past few years, the sector’s performance has steadily improved. In 2017, the average score for Gasunie was approximately 0.11 incidents per 1,000km per year.

* The EGIG average for 2017 was not yet known at the time of publication.

CO₂ emissions according to the GHG Protocol

We report in accordance with the standard of the Greenhouse Gas Protocol (GHG Protocol). This protocol for greenhouse gases distinguishes various categories (scopes), ranked according to the origin of the greenhouse gas.

Scope 1
Scope 1 includes all emissions that are a direct result of our own activities (e.g. the CO2 emissions of gas-fired compressors and engines used for compression, and our own gas consumption for heating buildings and for the boilers at gas receiving stations). This category also includes the CO2 equivalents due to methane emissions, and the emission of hydrofluorocarbons (HFCs), which are used in cooling processes.

Scope 2
Scope 2 includes the indirect emissions of energy we have procured (e.g. from an electricity company). In our case, the CO2 equivalents in Scope   come mainly from the use of electricity for electrical compressors and for the production of nitrogen. Scope 2 also includes the electricity consumed in our offices and our installation buildings.

Scope 3
Scope   includes all other indirect emissions resulting from our business operations (e.g. road, air and rail travel and energy required for producing the nitrogen we procure).

From consumption to CO₂ equivalents

The table below shows the calculation of the CO2 equivalents for 2017 for the largest sources of emissions, broken down by country (the Netherlands and Germany). The conversion factor for electricity consumption is based on the statement from the energy supplier (2016 fuel mix). The conversion factor for the network losses is derived from the IPCC Fourth Assessment Report ‘Climate Change 2007’ (Direct Global Warming Potential, Methane, time horizon 100 years).

NOₓ emissions

Our NOx emissions over the past 5 years were as follows:

NOx emissions 2013 2014 2015 2016 2017
(in tonnes)          
Netherlands  365   130   89   70   83 
Germany  101   40   47   29   29 
Total  466   170   136   99   112 

Our NOx emissions have decreased over the past years. This decrease was mainly due to the fact that electrically-powered compressors are being used instead of gas-powered compressors. NOx emissions increased in 2017 because of the use of gas compression, in particular at the Ravenstein and Ommen compressor stations.

Natural gas consumption

Our natural gas consumption over the past 5 years was as follows:

Gas consumption 2013 2014 2015 2016 2017
(in million m3)          
Netherlands  111.9   67.1   51.3   50.4   53.1 
Germany  64.3   27.8   31.2   23.5   22.1 
Total  176.2   94.9   82.5   73.9   75.2 

Our natural gas consumption depends in particular on the demand for natural gas and the weather conditions during the year. It is striking that natural gas consumption has decreased over the past several years. This decrease can be accounted for in part by the increased use of electrically-powered compressors.

Electricity consumption

Our electricity consumption over the past 5 years was as follows:

Electricity consumption 2013 2014 2015 2016 2017
(in million kWh)          
Netherlands  441.2   431.3   548.9   685.9   690.2 
Germany  7.4   5.8   6.9   7.3   7.5 
Total  448.6   437.1   555.8   693.2   697.7 

Our electricity consumption depends on the use of our electrically-powered compressors and the energy required for nitrogen production. A small percentage of the electricity consumption is required for our offices. The quantity of electricity consumed in 2017 was comparable to the level of 2016.

Environmental irregularities

We keep records of environmental irregularities in order to learn from these and, where possible, take adequate action to limit environmental damage in the future. Of the total of 157  nvironmental irregularities, we ourselves did not pick up on any irregularities in 12 cases. The number of environmental irregularities reported per focal area for Gasunie in the Netherlands and Germany was as follows:

Environmental non-compliance 2016 2017
Deviations from laws and regulations 2 -
Deviations from environmental care systems - -
Environmental incidents 64 54
Environmental complaints 101 103
Total  167   157 

Significant fines for non-compliance with environmental laws and regulations

Gasunie received and paid one fine in 2017, to the amount of € 563,415.00. This was a fine from the Dutch Emissions Authority (NEa), imposed for failure to submit data to the NEa on time concerning the CO2 emissions trade in the years 2012 to 2014, inclusive.
