Is the lack of comprehensible sustainability criteria an obstacle to growth in the sustainable finance sector? In which way do policy measures aimed at a sustainable financial market interact with climate policy instruments? Can investors advance sustainable financial investments effectively by exercising their voting rights?

On 22 September 2021, the 90-minute panel discussion was organised by the Sustainable ZEW initiative.
