In order to inform policies, science community and public, our research project seeks to improve expertise in the field of industrial relations, to builds on and contributes to environmental responsibility in Europe by analysing an impact of relevant national and sectoral (public and transport) EU and national green policies on level, scope and modalities of collective bargaining/agreements and role of social dialogue and collective bargaining in managing transition to a low carbon economy in just and fair manner for workers and local communities. It will conduct six case studies in Spain, Greece, Portugal, Poland, Serbia and North Macedonia with the cooperation of research institutions with key players of industrial relations in respective countries - trade unions, employer organizations and labour decision making –, and it will be possible to conduct a research based on empirical data. The project is following the 13 legislative proposals that aim at aligning EU climate and energy policies with the new climate targets set by the recently adopted Climate Law – a GHG emission reduction of at least 55% by 2030 compared to the 1990 levels, and climate neutrality by 2050. The CERP project also deals with the rethinking and setting up European social dialogue measures for implementation of REPowerEU and other Green New Deal policies. The final result of research will be country specific comparative study, which should provide evidence-based data on ongoing trends in 6 EU Member States and Candidate Countries with specific and different industrial relations and to provide recommendations for further theory and practice in Europe.
