The Dutch TROPOMI space instrument creates daily global maps of carbon monoxide (CO) in the atmosphere. Researchers from SRON and TNO have now measured CO emissions over a full year from the 21 largest European steel plants. The preprint is available on EGUsphere.
Together, these are responsible for 77% of European and 7% of worldwide steel production. The satellite measurements confirm the reported values for the majority of the monitored plants.
CO is a pollutant but not a GHG. 2019 data may be higher than EU industry’s current production.
