Working towards ‘intergenerational fairness’ (IGF) (or towards ‘justice’, ‘responsibility’, ‘solidarity’) first requires a solid understanding of the term ‘generation’ and the kinds of generational comparisons one can make.
Two key kinds can be identified:
1) Relations between young and older generations at a certain point in time (eg. a ‘young-old comparison’)
2) Relations between all those alive today, and all those who will live at a specific time in the future (eg. a ‘people today-people tomorrow comparison’)

Different generational issues lend themselves to different methods. When looking at voting rights, we take a ‘snapshot’ of a society (‘young-old comparison’) and find that young people are excluded from voting. Whereas, when looking at climate change, we look its impacts across an entire lifetime. In this way, we consider whether people living in the future, who will experience increased temperatures and extreme weather conditions, have been treated unjustly across their entire lives compared to people living today.

Dealing with both these kinds of intergenerational (in)justice is not a zero-sum game: they can be part of the same process and a unifying endeavour for a global community.

In our view, the key issues relating to IFG on a European level are 'presentism', climate change, national debts, peace, education, fake news/disinformation, youth democratic participation, pension and welfare systems given demographic change, and housing and labour markets.
