Anniversary Congress – 60 Years Lejeune Association Management 31 October 2024

Our Anniversary Congress start in .........


 ‘At the Helm of Change’  

It is with great pleasure that we invite you to our Anniversary Congress on the occasion of the 60th anniversary of Lejeune. This will take place on Thursday, 31 October at the iconic Madurodam park in The Hague. The day will be dedicated to the sustainability transition with the theme: 'At the Helm of Change'. The programme will be held in the Dutch language

If you are a board member, committee member, association professional, or a member of a trade organization, then this day will be very interesting for you!  


We are organizing an inspiring afternoon including a keynote presentation by transition expert Prof. Jan Rotmans. He will discuss with us the role that trade organizations can (and do) play in the sustainability transition. Following this, we will offer five expert breakout sessions with current themes, such as the implementation of AI for your trade organization, tackling CO2 reduction, establishing a vision and strategy, initiating innovation, and the impact of the Corporate Sustainability Reporting Directive (CSRD) on your members.


The Mans Lejeune Award 2024 will also be presented this afternoon. This Award is named after our founder, who early on recognized the importance of (European) cooperation between companies. The Mans Lejeune Award recognizes organisations that distinguish themselves through successful sector-level collaboration.

From 3 April 2024, all sector organizations can register for this prestigious award. Keep an eye on our website, social media, and newsletter for updates.
