Environmental impacts

A strong focus on sustainability is at the heart of our strategy and our purpose – To power a world where people, businesses and nature thrive together. We help societies to reach carbon neutrality, and our customers to grow and decarbonise their processes in a reliable and profitable way, in balance with nature.

Environmental impacts in 2023

Energy

In the future, the energy system – and Fortum’s portfolio – will be based on renewable energy, increasingly clean gas (e.g., hydrogen) and nuclear power. By improving the energy efficiency of our power and heat production, we can also reduce flue-gas emissions to the environment relative to the produced energy and decrease production costs.

Fortum’s power generation in the Nordic countries is mainly based on CO2-free hydro and nuclear power. A minor share of Fortum’s power generation is currently based on wind.

Fortum also has generation of district heating and cooling. Fortum’s target is to end all coal-based generation by the end of 2027.

A functional society requires an uninterrupted and reliable supply of energy. In 2023, the hydro availability was 96% and nuclear availability of Fortum’s total nuclear fleet, excluding TVO’s third Olkiluoto power plant unit (OL3) was 87%.

 

Emissions

Energy production and other production operations generate emissions to the environment, such as to air and water. We aim to control emissions caused by our operations and to reduce their environmental impacts by using technological solutions and cleaning technology.

Greenhouse gases that accelerate global climate change are generated primarily from the use of fossil fuels and the combustion of fossil-based waste. Flue-gas emissions causing local environmental and health effects are generated from all combustion.

Water

Water availability is a prerequisite for Fortum’s operations using cooling water, in particular at our nuclear and other condensing power plants, as well as for hydropower production. Our responsibility for water use is related not only to water volume and availability, but also to its quality and to the aquatic habitat. We also offer services to our customers for the treatment, analysis, purification, utilisation and increased recycling of their waste and sludge waters and other severely polluted waters.
