Microsoft continues its carbon credits investment spree, announcing a newly signed deal, this time with Norway-based heat and power provider Hafslund Celsio.
Under this agreement, Microsoft is investing in 1.1 million tons of carbon removal credits to be delivered over a ten-year period through the carbon capture mechanism, which will be installed by Hafslunt at the Klemetsrud waste-to-energy facility in Oslo—the country’s largest plant of this kind.
This site, operated by Hafslund Celsio, will host a carbon capture and storage (CCS) system projected to be able to capture about 350,000 tonnes of CO2 annually.
As the largest waste-to-energy plant in Norway, the Klemetsrud facility incinerates approximately 350,000 metric tons of sorted residual waste each year, utilizing the surplus energy to produce electricity and heat.
During these waste-processing operations, the facility emits both biogenic carbon dioxide emissions from burning organic material like paper and cardboard, as well as fossil CO2 emissions that come from incinerating inorganic materials like plastics.
To reach a volume of ~350,000 tonnes of CO2 removed on an annual basis, the CCS technology on this site will tackle about half from the biogenic emitted CO2, and the remainder from the fossil CO2 emissions.
The carbon credits for the agreement with tech giant Microsoft will come from the biogenic emissions captured at Klemetsrud, while Hafslund Celsio has pointed out that the fossil portion of the removed emissions will lower the annual emissions of the City of Oslo by 20%.
Once captured, the carbon dioxide will be transported with a ship to the Northern Lights facility, where it will be processed and permanently stored in geologic formations.

As clarified in the deal announcement, the ambitious carbon capture operations at Klemetsrud are slated to begin in 2029.
Hafslund’s CCS deployment at Klemetsrud forms part of Project Longship, a full-scale carbon capture and storage project backed by the Norwegian government.
This pilot CCS installation at a waste-to-management plant is meant to serve as a blueprint that can later be applied to a network of 500 other waste-to-energy plants across Europe.
