As the EU sets the bar high with its climate targets – most recently striving for a 90% reduction in net greenhouse gases (GHG) from 1990 levels by 2040 – companies across the board are feeling the heat to curb their environmental impact. 

Amid this ambitious push toward decarbonization, countless sustainability professionals are doing incredible work for the planet. Yet their stories often go untold. 

At Coolset, we want to change that narrative by shining a light on the emerging sustainability managers working hard behind the scenes. Our goal? To celebrate these pioneers while inspiring the next generation of sustainability talent to tackle the urgent environmental challenges facing us all.

Introducing Coolset’s Future 15

How we selected the Future 15

A four-person judging panel carefully evaluated a wide range of factors for each of the shortlisted candidates. These included impact, leadership abilities, and potential for future achievements, among others.

This was crucial to identify the exceptional talent who truly stood out, reflecting the initiative's commitment to celebrating and nurturing the pioneers of the sustainability transition.
