Promoting equality at all ages is essential to achieve intergenerational fairness. Ageism is the only ground of discrimination covered by the EU treaties, which has so far been overlooked in the EU's policy landscape. The Intergenerational Fairness Strategy must include a dedicated Action Plan to Combat Ageism, which would create a roadmap to eliminate inequalities across the lifecourse and to promote equality for young and old. It would replace ageist narratives with a human rights-based approach, contributing to better enforcement of existing anti-discrimination laws, improved data collection, disaggregated by age and other characteristics. This Action Plan will work hand in hand with the existing EU equality action plans/strategies on gender, disability, LGBTI+, Roma and race enriching EU's intersectional ambition. This strategy will aim to eliminate any ageist practices that affect human dignity and the equal enjoyment of fundamental rights at all ages, pulling together the necessary resources for young and old to fulfil their potential and have full and equal access to society. It will steer EU's attention to the reality of longer lives and the need for fair, inclusive and resilient societies for all generations. Combating ageism is not only a human rights imperative —it is central to building resilient, inclusive, and just societies.
