Joint, comparative exploratory research on impacts and costs of just green transition in the Western Balkans is the laboratory and test-bed for the knowledge transferred/acquired during exchanges to raise the research excellence bar. Co-working for green transition conceptualization, implementing a mapping exercise (participatory and gender-sensitive), carrying out a comparative study of green transition processes and policies vis-à-vis spatial planning and regional policies, and empirically researching costs and impacts of just green transition in the WB, compose the exploratory research.
