Towards realising the redefined kelvin

In 2019 the kelvin was redefined in terms of the Boltzmann constant. Here we outline the implications of that redefinition for the realization and dissemination of the unit of temperature. We describe the progress towards realizing the redefined kelvin and outline the prospects for temperature traceability into the 2030 s.
