- | The remarks below refer to production of cement clinkers and clinker grinding (only relevant as a source for particulate matter). The clinker-burning with intensive use of energy emits climate-relevant gases. CO₂ accounts for the great majority of these emissions, but heavy metals are important too. Information about the key source relevance can be found in [[sector: | + | The remarks below refer to production of cement clinkers and clinker grinding (only relevant as a source for particulate matter).
