Efficient production - smaller footprint

Technological advances have resulted in a significant increase in production efficiency, which in turn means less impact on the environment.

Today and in the future, we will be choosing the solutions that can ensure minimal impact on the environment at maximum efficiency, while continuing to contribute to the development of renewable energy and improving the efficiency of the circular economy.

The circular economy creates an opportunity for recycling

We will develop products and services in accordance with the principles of circular economy, where the sustainable use of natural resources and recycling are central.

For example, Enefit technology makes it possible to use shredded old tyres as raw material.With Enefit technology, up to 10% of oil shale can be replaced with shredded old tyres and used to produce oil, semi-coke gas and electricity. Tyre shredding capability in Estonia does not yet allow the technology to be fully utilized.

Energy from waste

At the Iru Power Plant in Tallinn, we use municipal waste as fuel to generate electricity and heat

In addition to oil shale, we use waste wood as fuel at the Balti Power Plant near Narva. By using waste, we can save up to 70 million cubic meters of natural gas per year.

Our expertise in energy production from waste tyres and waste wood is valued also outside Estonia.

The use of waste tyres and waste wood for energy production will create value. Waste plastic is also a potential raw material for the production of liquid fuels.

From the by-products of production, we will build solar farms and grow the yield of Estonian fields

We can use oil shale waste rock and left-over oil shale ash from electricity production for building, road construction and agriculture. This will help conserve other non-renewable natural resources.

  • We will sell limestone gravel made of waste rock.
  • Soon, we will build a solar farm on the territory of the Estonia Mine's former ash depository, where the waste rock base with a proper incline will improve the efficiency of the solar power plant. In this way, another solar farm and a pumped hydroelectric power plant will be built on the territory of the Estonia Mine.
  • Ash generated from oil shale energy production will be used, for example, in building, road construction and agriculture to increase crop yields.
  • Smaller impact on the climate and cleaner air

    Climate change has a wide-ranging impact on the ecosystems and economies of the world, including Europe, as well as on human health and well-being. In order to limit climate change, it is necessary to achieve global carbon neutrality by the middle of the 21st century. Carbon neutrality means the balance between carbon emissions and its removal from the atmosphere.

    To achieve this, greenhouse gas emissions must be cut short. The European Union's climate package obliges to reduce greenhouse gas emissions by 40% by 2030 compared to 1990. Eesti Energia's production units today emit over half less of carbon dioxide compared to 1990. This has been achieved due to a reduction in production volumes and technological developments, including the use of new and more efficient technologies.

    Vaivara Monitoring Station

    The permanent air-quality monitoring station established in cooperation by Eesti Energia and the Environmental Investment Centre to Sinimäe, Vaivara rural municipality, was connected to the Estonian national online network of monitoring stations

    The permanent monitoring station measures the content of several components in the outdoor air as well as the wind direction, speed, air humidity and temperature, which also provide valuable information for future air quality control. The project was carried out in cooperation with the Environmental Investment Centre and with its partial financing.

    Information on the national network of monitoring stations is available at

    Estonian air quality is one of the best in Europe

    To monitor air quality, the European Environment Agency (EEA) and the European Commission use the European Air Quality Index, which is based on information from more than 2,000 air quality monitoring stations across Europe.

    According to the index, Estonia's air quality is better than in many other European countries. Check the air quality in European countries, including Estonia at

    Cleaner mining water will be returned to nature

    Mining water is pumped out of the mine during extraction, cleaned of excess sediment in sediment pools, and then discharged into natural bodies of water. Mining water is mainly based on rainwater. A smaller part comes from groundwater and neighbouring closed mines.

    In 2016, we built an underground sediment pool in the depleted chamber blocks of the southern part of the Estonia Mine. Thanks to the novel solution, valuable forest land remained on the ground. Also, thanks to a larger pool size, it is now possible to significantly extend the sedimentation time of the suspension, making the water returning to nature cleaner than ever before.

    In areas where the groundwater is affected by mining, the water supply is based on water pipelines and deep bore wells established by Enefit Kaevandused AS.

    The cooling water from electricity production is returned to nature just as clean

    Power plants near Narva use water from the Narva River and the Narva Reservoir as cooling water. The cooling water is returned to the same body of water after passing the cooling system. The composition of the water returned to nature does not change.

    Only the temperature of the water leaving the channel outflow of the station into the Narva River is by 3 - 4 °C higher.

    We preserve ecological reserves

    Selisoo Nature Reserve, the protected Muraka Bog and Kurtna Lakes Reserve are located in the vicinity of Estonia Mine. We value the natural environment and therefore leave buffer unities at the border of protected areas - a 300 meter wide buffer zone is kept to protect the Muraka bog. In the vicinity of ecological reserves, we do not establish production support facilities, such as ventilation shafts. An extensive monitoring network has been set up to supervise the environmental impact of the mine.

    Environment is important to us

    Many of our offices are certified by the European Green Office system

    We have recieved the Responsible Business Gold Label three times

    Our energy production is diverse and respectful of nature

    We solve important environmental problems. Our focus is on old tires and waste wood

    Our environmental principles

  • Our systematic environmental activities are based on a set of common principles that are consolidated to a uniform Environmental Policy (pdf).
  • We use an environmental management system that complies with the international standards ISO 14001 and EMAS.
  • We summarise our environmental activities and plans. Read Eesti Energia's Annual Reports that include the Environmental Reporting section.
  • We pay public attention to environmental issues and work with key persons to address them. We organise an Environmental Day every year.
