This study with an insiders’ perspective may contribute to the understanding of Poland’s troubled transition towards a net-zero economy. It utilizes Finnemore and Sikkink’s life cycle of a norm framework within the context of net-zero ambitions at a national level. The findings are based on 15 semi-structured interviews and a mapping of Poland’s decarbonization field both undertaken with insiders of that field. Findings based on the sample reveal initial results that various norm entrepreneurs advocate for operationalizing a netzero target in Poland, typical for the norm emergence phase, clashing with strong opponents of change: norm antipreneurs. The findings provide hints of a tipping point and further cascadization of the norm. Due to the only ongoing cascadisation, no further internalization or taken-for-granted status of the net-zero norm was found. This study contributes to the understanding of the field by its insiders. By following existing research and adding a new perspective it contributes to a better understanding of the diffusion and adoption of climate policy and understanding of the decarbonization field in Poland.
