We sign the world’s first agreement with a property company regarding the purchase of permanent negative emissions. The agreement covers both permanent negative emissions linked to the company’s purchase of district heating, as well as independent negative emissions to mitigate the climate impact of the company’s construction of new properties.
The year's highlights
During the year, we took several important steps to develop our offerings and strengthen the energy system in Stockholm. From new pricing models and initiatives to increase resource efficiency to major investments in carbon capture and energy storage technologies, these developments show how we continue to meet both customer needs and the broader societal transition.
Important events in 2025
January
On 1 January, we introduce a new pricing model for district heating. This model rewards customers who make energy and power savings, especially in colder temperatures when district heating networks are under the most strain.
At the same time, we introduce a new pricing model for waste management services with the aim of increasing plastic sorting and thereby reducing carbon dioxide emissions.
