This report summarises of the key insights from CFM TRACTION project results in Germany and Poland. The project focused on refining the concepts and exploring socio-economic impacts of two policy instruments supporting industrial decarbonisation: Project-based Carbon Contracts for Difference (CCfDs) and Climate Contribution. The assessment was conducted in Germany and Poland to capture the impact of different national settings highlighting the similarities and differences between the two countries in terms of expected policy impacts. In particular two main assessments are of interest to compare, namely the scale of funding required for governments to implement the CCfDs and the distributional impact of the Climate Contribution. The report concludes with the summary of lessons learnt for the implementation of industrial decarbonisation policy for Europe as a whole.
