Environmental responsibility 

We recognise the impact of our activities on the environment. We strive to minimise the adverse impacts of our operations and develop solutions that protect soil, water, air and biodiversity. We are committed to complying with environmental legislation and always seek to go beyond what is required by law.

Awareness of the environmental impacts of our operations is an important part of being a sustainable mining company. We therefore see it as very important to assess the environmental impact of our mining projects, and to develop best practices for sustainable mining. When an exploitable deposit is depleted, the mining site is closed and the environment is restored to its former state, or a new use, for example, recreation, that is safe for human health.

Endomines’ long‑term goal is to achieve fossil‑free gold production along the Karelian Gold Line by 2035. This target guides our long‑term development and provides the foundation for reducing the company’s climate impact.

Progress towards the target is measured through carbon dioxide emissions (Scopes 1 and 2) generated per ounce of gold produced. Key measures for achieving the target include improving energy efficiency and transitioning to renewable energy sources. We also monitor total emissions across the entire value chain (Scopes 1, 2 and 3).

CO2 emissions t per ounce of gold produced

These are generated by mining activities, for example from vehicle and machinery exhausts.

Target

Scope 1 and scope 2 Reduction of CO2 emissions by 5% per year. We measure the reportable figure in terms of t CO2 per ounce of gold produced.

Measures

Gradual transition to biofuels and renewable electricity, and measures to improve energy efficiency.

Status

Year/Quarter	Q1	Q2	Q3	Q4	mean (Q1-Q4)
2025	0.74*	0.71*	0.65	0.88	0.74
2024	0.78**	0.67**	0.55**	0.91**	0.72**

* Emission intensity figures for Q1 and Q2 of 2025 have been recalculated using the GHG Protocol methodology.
** Due to changes in the calculation methodology, 2024 emission data is not comparable with the 2025 results.

Endomines’ objective for water management is to ensure that water discharged into the environment is clean so that it does not degrade surrounding water bodies or their ecosystems. Achieving this requires maintaining a closed water circuit within the mining area and ensuring the quality of water released from the site.

We maintain a closed water loop in our processing plant, aiming to recycle water from the mine site so that no water needs to be pumped in from outside the site to the mill process. By maintaining internal water recycling we reduce our discharges to the environment.

Discharged waters and seepage waters from the mining area are monitored at several control points. Discharged waters are assigned target levels in the environmental permit for water acidity as well as for suspended solids, nickel and arsenic concentrations. In addition, we regularly monitor the impacts of mining operations on nearby water bodies and fish populations.

Biodiversity is a central component of Endomines’ environmental responsibility. Mining activities inevitably alter land use and ecosystems, which is why we aim to identify, assess and manage biodiversity impacts throughout the entire lifecycle of our operations—from exploration to mine closure.

We work systematically to identify ecological impacts, minimize them, and support the development of habitats for local species. Biodiversity surveys are conducted as part of environmental impact assessments during the planning of new operations. In addition, we promote the restoration of areas taken out of use already during active mining.

This is incorporated into operational planning and into the continuously updated closure plans for our mines.
