Abstract
The redefinition of the SI unit the kelvin in May 2019 opened new possibilities for the realization, dissemination and measurement of temperature. Besides the two practical temperature scales that were in place before the redefinition, now, through the mechanism of the mise en pratique for the definition of the kelvin, temperature can be realized and disseminated through primary thermometry approaches with direct traceability to the redefined kelvin. Initial progress towards realizing the redefined kelvin will be discussed, with emphasis on temperatures >1235 K and <25 K.
