Auris Energy Sustainability
At Auris Group, we believe that the most effective way to transition to a zero-emission society is to help companies reduce their carbon dioxide emissions and increase their energy efficiency, every day. For companies to remain competitive, and for society as a whole to move towards a cleaner future, we need continuously better and comprehensive energy efficiency, and the cleanest possible energy that can always be relied upon. This guides the operations of our Group today and in the future.
In 2025, Auris Energy continued its determined journey towards becoming a more sustainable, service-oriented, and versatile energy company.
The year 2025 was a period of purposeful development for our Group. We strengthened our position in renewable gases and electricity-based energy services. At the same time, our core business remained stable. We made investments that improve our competitiveness and accelerate our customers’ transition to low-emission energy.
In the biogas business, our most important achievement was the completion of the expansion of Mäntsälän Biovoima. The doubling of the plant’s production capacity makes us a significant Finnish biomethane producer and provides a good foundation for our next biogas projects. The technology solutions we have deployed in Mäntsälä, such as the gas chromatograph and compressor station, enable biogas to be fed into the national transmission network and sold to the European market. In the autumn, we also launched the ISCC EU certification process for biomethane production in Mäntsälä. The process will be completed in spring 2026 and further support the expansion of the
business.
In the Energy Services business, we continued to invest in electricity-based solutions, as well as energy recovery and storage. The energy partnership agreement we signed in the latter part of the year with the Fazer chocolate factory to be built in Lahti is a good example of this. The agreement demonstrates that our solutions meet the demanding needs of industrial customers and that we are able to serve as a long-term partner even in major projects.
In gas sales, the year under review progressed in a controlled manner on the whole. The exceptionally warm weather at the beginning of the year affected our sales volume, but sales developed better than expected towards the end of the year. During the year, we focused on the development of operating models, pricing, and the management of the gas balance. At the same time, gas prices fell and the gas market became more stable than in the preceding years, although it was still sensitive to fluctuations in weather and geopolitics
Mäntsälän Biovoima’s investments and expansion projects strengthen our position in the biogas market.
In gas distribution, we focused on the security of supply and the long-term development of our network. The distribution network renovation programme progressed according to plan, methane emissions decreased further and the security of supply was 100% throughout the year. We also replaced a large proportion of our old gas meters with new, remotely readable versions. The project will continue in 2026. The new meters will make the measurement of gas volumes even more reliable and further improve the accuracy of invoicing, making our service even smoother for the
customer.
Our customer satisfaction remained at a high level throughout the year. In particular, we received positive feedback for our solution-oriented approach, the reliability of our service and effective cooperation.
Safety and the professional expertise of our personnel are the cornerstones of everything we do. There were no lost time injuries to our personnel during the year, which is a testament to our strong safety culture. The high NPS figure of 59 in our personnel survey, in turn, speaks to the well being and trust of our employees.
I want to take this opportunity to thank our employees, customers and partners for the past year and their good cooperation.

ESG Progress in 2025
Auris Energy operates sustainably and with a focus on ESG for the benefit of its customers, the environment, and society. In 2025, we took several concrete steps forward in all areas of sustainability and ESG.
Environment
- Our goal is to achieve carbon neutrality in terms of direct emissions from our own operations by 2035.
- In 2025, we further developed our energy solutions towards lower-emission production. We continued to invest in electricity-based energy services, such as heat pumps and hybrid systems combining electricity and gas in a cost- and emission-efficient way.
- Methane emissions in our gas distribution network remained at a very low level, below 0.1% of the total gas distributed. Security of supply was 100% throughout the network, and we continued to invest in network development and renovation.
- We strengthened the role of renewable energy in our business. The expansion of the Mäntsälä biogas plant was completed in 2025, doubling the plant’s production capacity. The expansion enables biogas to be fed into the national transmission network and further into the European market.
- In addition, we supported our customers’ emission reductions by developing energy-efficient solutions for industry and real estate and by optimising energy use.
Social Responsibility
- We invested in employee satisfaction and the employee experience, which was reflected in a high NPS score (Net Promoter Score) in our employee survey.
- During the year, we hired six new employees, bringing our total workforce to 53.
- We also offered internship and thesis opportunities for energy sector students to support the future workforce of the industry.
- Workplace safety remained at a high level, and we continued to develop it. No workplace accidents occurred for our own employees, and there was one for contractors.
- Our sickness absence rate remained low, at just 1.1%.
- Customer satisfaction also remained high. In customer surveys, our NPS score rose to 72.
Good Governance
- We wrote the 2025 sustainability report with reference to the GRI standard and had it verified by EY. This ensured the transparency, reliability, and comparability of our reporting.
- We further developed risk management and data collection to meet the requirements of new regulations, such as NIS2.
- We assessed ESG risks and opportunities related to our business as part of our sustainability management development.
- In 2025, ESG themes became even more central to our governance. We included ESG metrics in the overall evaluation of the executive compensation system, so sustainability goals will have a clearer impact on management’s compensation.
- The implemented whistleblower channel provided all stakeholders with a safe way to report unethical conduct. No cases related to bribery or corruption were reported during the year.
- We continued our active participation in several industry cooperation networks, including the Finnish Energy Industry Association, Finnish Biocycle and Biogas Association, Gas Association, and WEC Finland.
