Environmental Protection and Sustainability across the Group

As a leading railway technology company, we therefore carry a great responsibility towards the environment, resources, and future generations. We are acutely aware of this and are committed to advancing railways with all our knowledge and diverse services in line with our vision motto: Enabling Future Mobility! Thus we make a significant contribution with our services and innovations to make rail as the most sustainable mode of transport for people and goods even more competitive. This motivates and drives us.

We at Rhomberg Sersa Rail Group view and monitor sustainability in all its facets and at all levels. But monitoring is not enough. We are taking targeted steps in our daily activities to progressively minimise our greenhouse gas emissions and move towards net zero. This includes using low-CO2 alternatives like electrified equipment at our construction sites, electrifying our vehicle fleet, switching to renewable energy at our locations, or changing from diesel to Hydrotreated Vegetable Oil (HVO) for track construction machinery. We are also aware that sustainability goes beyond environmental protection.

RSRG has conducted a double materiality assessment in accordance with the EU Directive on non-financial reporting (CSRD). This involved identifying opportunities and risks in the area of sustainability and specifying topics in order to develop a sustainability strategy.

As part of this analysis, internal workshops were held and a comprehensive stakeholder survey was conducted in which employees, customers, suppliers and other interest groups were asked for their opinions on the most important sustainability issues. In this way, RSRG aims to ensure that not only the internal perspective is taken into account, but also the opinions of its stakeholders and interested parties.

The results of this analysis are presented below, showing all the key topics that are therefore subject to reporting requirements. The weighting of relevance ranges from internal (low relevance) to external (high relevance).

RSRG has subsequently positioned itself comprehensively to strategically develop the key topics, strengthen the area of sustainability and create transparency.

These topics are defined in the sustainability vision via key focus areas.

Both the Paris Agreement (2015) and the EU Green Deal (2019) pursue the overarching goal of combating climate crisis and accelerating the transformation to a sustainable, low-carbon economy. 

The Paris Agreement aims to keep global warming well below 2 degrees Celsius compared to pre-industrial levels and to strive to limit the warming to 1.5 degrees Celsius.

The EU's goal is to make Europe the first “climate-neutral” continent by 2050.

In line with legislation, politics, and our customers, at RSRG we are making a concrete contribution and have therefore developed a climate strategy to achieve the net-zero goal by 2050. All markets have been included in this strategy, and each market is individually measured on this journey. As part of this process (according to the GHG Protocol), we will annually review our climate strategy.

Rhomberg Sersa Rail Group Ireland has introduced a number of changes to materially reduce CO2 emissions. 

In 2023 the Rhomberg Sersa maintenance team converted the On Track Machine (OTM) fleet - which it operates on behalf of Iarnród Éireann - Irish Rail (IÉ)  - to Hydrotreated Vegetable Oil (HVO). HVO is a renewable diesel replacement produced using vegetable oils and fats.

A trial in early 2023 saw the the biggest fuel consuming machines converted to HVO on a phased basis. Once proven both safe and successful, other commissioned machines were converted with a 90% reduction in carbon emissions compared to diesel. 

The machines were later an integral part of Irish Rail's first net zero ballast cleaning site. The historic first meant that all machinery and facilities used on site during a weekend of work in October 2023 were operated on alternative biofuel and power sources. This resulted in a 90% reduction on the typical carbon emissions from such a work site. 

The works took place between Mosney and Laytown on the Dublin-Belfast line when three quarters of a mile of ballast - the stone under the rail track - was removed and replaced with the assistance of contractors including Rhomberg Sersa. All plant, engine power, vehicles, OTMs and small tools were operated on either bio fuel, solar or batteries. As a result, there was a 90% reduction in the carbon emissions. The remaining 10% was offset by planting 300 trees in Wexford, resulting in a net zero worksite. 

A second project by Rhomberg Sersa in Ireland to reduce reliance on fossil fuels was the replacement of engine oil with Panolin. 

Panolin is the brand name of a synthetic lubricant which is made from ‘esters’. Esters are created through the chemical reaction of a carboxylic acid and an alcohol.  A clean product, Panolin has a number of major benefits:  

• It has a life cycle of up to seven years meaning less consumption  
• As it needs to be replaced less often, there is less labour required on the OTMs   
• It is biodegradable therefore reducing environmental impact should there be a spill 

Although Panolin is more expensive than fossil based engine oil, overall there is a net gain, particularly from an environmental side.  

The company is continuing to work to identify areas where emissions can be reduced.

This strategy aligns with that of its client, Irish Rail, which has a corporate climate action plan bringing it up to 2030. It aims to halve its carbon emissions by 2030 and decarbonise completely its diesel locomotive fleet while scaling up electrification and introducing green hydrogen fuel.

The ambitious plan will see the State transport company reducing its emissions by more than 71,000 tonnes of CO2 annually while expanding rail services. This is in line with Government plans to scale up Irish public transport in coming years and reduce car dependency.

In 2022, diesel fuel accounted for 82 per cent of Irish Rail’s overall emissions.

New machines which have been purchased by Irish Rail and will be operated by Rhomberg Sersa, are currently going through the commissioning process. Once commissioned, these machines will also be converted to HVO.

We operate an integrated management system that enables us to implement the goal of continuous improvement in practice. We place particular focus on the areas of corporate governance, process management, environmental protection, occupational safety, and compliance.

In the development and expansion of infrastructure, it is not always easy to concretely demonstrate the quality of individual products. Our quality management system according to ISO 9001 helps us to structure the processes and operations of our company, to constantly reconsider them and thus ensure a consistent quality of our projects.

Especially in the development and expansion of infrastructure, large amounts of raw materials are used and ecosystems are affected. With the introduction of the environmental management system according to ISO 14001, we have made the identification and implementation of environmental protection potentials an integral part of our corporate culture.

Our compliance management system according to ISO 37301 helps us to identify and control compliance risks. Through clear structures and regular training, we ensure compliance with laws and regulations. Transparent documentation and continuous improvement are integral parts of our system.

We ensure health-promoting working conditions, thereby enhancing the fitness and well-being of our employees and clients. Every employee should feel responsible for their own health and safety and that of the people in their immediate work environment.

To ensure that our efforts and achievements are subject to objective review, we have our sustainability performance assessed annually by EcoVadis. The assessment covers 21 criteria in four areas: environment, labour and human rights, ethics and sustainable procurement.

All RSRG companies (except those in North America) have already been assessed by EcoVadis with the following results:
