We report a summary of the technical achievements of the European Metrology Research Programme (EMRP) 'Implementing the new Kelvin' (InK 1) project. In short these are: - The first determination of definitive thermodynamic temperatures for the point of inflection of the high temperature fixed points of Re-C, Pt-C and Co-C as well as a new evaluation of the Cu freezing point. - The first trial of the new dissemination mechanisms for thermodynamic temperature at high temperatures, as described in the mise en pratique for the definition of the kelvin (MeP-K) - A new ultra-low uncertainty thermodynamic evaluation of T-T90 from about 30 K to 303 K, with particular emphasis on temperatures around the water triple point (273.16 K) - The first re-evaluation of T-T2000 from 0.02 K to about 1 K with an uncertainty of
