Defining decarbonisation pathways

Building on the understanding of our emission hotspots across the value chain, SSE structured its decarbonisation approach to move from insight to action. Rather than focusing on isolated initiatives, the Group adopted a structured methodology to explore how different levers can be combined to drive meaningful emission reductions.

“By modelling scenarios such as HypexBio based solutions, we gain a clearer understanding of where the most meaningful emission reductions can be achieved, and under which conditions they can be developed and scaled. This approach helps us identify promising pathways, while progressively assessing their feasibility, scalability and alignment with our business and industrial realities.”

CLIMATE | SCENARIO-BASED APPROACH TO 2035

SSE developed a set of 16 scenarios to define its decarbonisation trajectory by 2035, each combining different levers across energy, operations and the value chain. Each scenario evaluates emission reduction potential over a 10-year timeframe, together with associated capital and operational expenditures, providing a comprehensive view of both impact and investment requirements.

This approach enables the Group to explore multiple pathways to reduce emissions, while assessing their feasibility, operational implications and potential return on investment.

By combining operational and financial perspectives, the scenario approach allows SSE to identify pathways that are both impactful and economically viable for the Group.

SSE structured its decarbonisation approach around three main families of levers, illustrated through concrete operational actions:

ENERGY TRANSITION & EFFICIENCY

Focusing on energy optimisation across operations, electrification of equipment and processes, and the transition to renewable energy sources.

Examples:

Replacing diesel-powered equipment with electric alternatives at production sites
Optimising energy consumption in manufacturing processes (e.g. blasting, mixing, heating)
Switching to renewable electricity contracts or on-site energy production

OPERATIONS & MOBILITY TRANSFORMATION

Addressing process optimisation, industrial efficiency and the reduction of fuel consumption across operations and logistics.

Examples:

Optimising drilling and blasting operations to reduce energy and material intensity
Reducing fuel consumption through fleet optimisation and logistics planning
Improving transport efficiency through route optimisation and load management

VALUE CHAIN & PRODUCT EVOLUTION

Targeting supplier engagement, material optimisation and the development and scaling of low-carbon product solutions.

Examples:

Working with suppliers to reduce emissions linked to raw materials (e.g. explosives inputs, chemicals)
Replacing diesel-powered equipment with electric alternatives at production sites
Substituting high-materials with lowercarbon lower-carbon alternatives where feasible manufacturing processes (e.g. blasting, mixing, heating)
Developing low-carbon product formulations and ensuring their availability at scale

OUR RESONANCE Foundation

Turning community commitment into action

The OUR RESONANCE Foundation serves as SSE’s dedicated platform to support environmental, innovative, social and societal initiatives in the regions where the Group operates.

Designed as an employee-driven and locally anchored mechanism, the Foundation enables employees and local stakeholders to propose projects that respond to concrete community needs. Proposals are reviewed by the Foundation’s Board, ensuring that supported initiatives align with SSE values and deliver meaningful local impact.

Through this structured approach, the Foundation transforms the Foster Communities pillar into tangible action, strengthening SSE’s engagement with local communities and reinforcing the values that guide the Group: responsibility, solidarity and long-term commitment.

These initiatives aim in particular to promote the quality of life of the communities connected to SSE’s activities.

Governance and Oversight

The OUR RESONANCE Foundation operates under the supervision of an independent Board chaired by Gilles de Preux, CEO of SSE Group.
The Board meets regularly to review project proposals, oversee funding allocations and ensure that supported initiatives remain aligned with the Foundation’s mission and SSE’s values.

“What makes the OUR RESONANCE Foundation meaningful is the engagement of our employees. Their initiatives reflect the needs of the communities where we operate and the values we share.”

Anna Darska
Vice-President
OUR RESONANCE Foundation

“Our activities are closely connected to the regions where we operate. Through the OUR RESONANCE Foundation, we support initiatives that help improve the quality of life in the communities where our employees live and work.”

Key progress in 2025

2025 marked the operational launch of the OUR RESONANCE Foundation, transforming the concept into a fully functioning philanthropic machanism across the Group.

Key milestones included:

Establishment of the Foundation governance framework, including statutes, regulations and a dedicated Board chaired by the CEO of SSE Group.
Consolidation of the Foundation’s sustainable funding model, combining an initial Group contribution of CHF 150,000 with annual financial participation from SSE subsidiaries (CHF 10,000 per entity), ensuring the long-term capacity of the Foundation to support community initiatives across the regions where SSE operates.
Launch of the first call for initiatives, inviting employees across the Group to submit projects supporting social, educational, environmental or community causes.
Review and approval of the first portfolio of initiatives across several countries, including educational, cultural and community-based projects proposed by employees and local partners.
Rapid mobilidation of the Foundation following the Crans-Montana tragedy, combining Foundation funding, company support and employee donations matched by SSE Switzerland to provide financial assistance to affected families and contribute to the cantonal relief fund.

These first initiatives demonstrate the Foundation’s ability to translate SSE’s values into concrete local action while strengthening engagement across the Group.

Impact across SSE

The first year of activity confirmed the strong engagement of employees and the relevance of the Foundation’s mission.

Through the initiatives supported in 2025, the Foundation:

Enabled employee-led community engagement across several SSE countries.
Supported social, educational and community initiatives benefiting local populations.
Strengthened relationships between SSE sites and their surrounding communities.
Demonstrated SSE’s commitment to solidarity and responsible corporate citizenship.

By empowering employees to act locally while providing a structured support mechanism, the Foundation contributes to creating a positive and lasting impact across the Group’s operating regions.

“Our activities are closely connected to the regions where we operate. Trough the OUR RESONANCE Foundation, we support initiatives that help improve the quality of life in the communities where our employees live and work.”

Administrator & Secretary of the SSE Group Board

Pillar 4: Foster communities

We believe that engaging with neighbouring communities can make a difference in improving their local life, while enhancing our employee sense of belonging.

“For me, it’s about understanding that our work matters beyond our buisness. Through the Our Resonance Foundation, we support local projects that make a real difference close to home. As a parent, I want my children to grow up seeing companies act responsibly within their communities.”

Dominic Zuber
Head of Quality Unit, SSE Civil Explosives & Valsynthese

Fostering strong relationships with local communities

The Double Materiality Assessment confirmed that community engagement and local development are important topics for SSE, reflecting the Group’s presence in multiple regions and its responsibility towards the communities where it operates.

In industries such as civil explosives and fine chemicals, operations are closely connected to local territories. Building trusted relationships with neighbouring communities and contributing to local development are therefore essential to the long-term sustainability of the Group.

Through the Foster Communities pillar, SSE support initiatives that improve quality of life, encourage local partnerships and create opportunities for employees and stakeholders to engage in meaningful projects.

This approach is structured around three key drivers: supporting community initiatives through the OUR RESONANCE Foundation, encouraging employee engagement and contributing to local devlopment across the regions where SSE operates.

Celebrating tradition and community

Across several countries where SSE operates in the mining and explosives sector, teams celebrate Saint Barbara, the patron saint of miners and explosives workers. This long-standing tradition reflects the shared heritage of the industry and brings together employees, retirees and local communities.

By honouring this tradition and recognising long-term service, these celebrations strengthen the sense of belonging within SSE tems and reinforce the bonds between the Group and the communities where it operates.

Structuring community engagement across SSE

In 2025, SSE reached an important milestone in the development of the Foster Communities pillar with the creation and operational launch of the OUR RESONANCE Foundation.

This new foundation marks a step forward in structuring SSE’s commitment to the communities where the Group operates. During the year, priority was given to establishing the Foundation’s governance framework, consolidating its funding and launching the first community initiatives across several countries.

Moew than a philanthropic mechanism, the Foundation provides a structured platform enabling employees, partners and local organisations to work together and support environmental, social and community projects rooted in local needs.

Through this collective approach, SSE aims to generate lasting positive impact in the regions where it operates, while reinforcing the values that guide the Group: responsibility, solidarity and long-term commitment.

“With the creation of the OUR RESONANCE Foundation, we have taken an important step in turning our values into concrete action for the communities around us. What makes this initiative truly meaningful is the engagement of our employees across the Group, who propose and support projects that respond to real local needs. Even if each contribution may seem modest, together they create a positive wave of impact. For us, this Foundation is not a marketing initiative — it is a long-term commitment that reflects our responsibilty toward society and future generations.”
