EHA2026 sustainability

EHA is committed to minimizing the environmental impact of both our organization and our community.

Our biggest opportunity to make a difference is with Congress, the biggest and most important hematology event in the European calendar.

In recent years, we’ve pioneered a range of new initiatives aimed at reducing our carbon footprint.

EHA2025 environmental progress report

Downloadable participation certificates

We reduced the use of both paper and printer ink by making the certificate of participation available to download on the Congress platform.

Transportation

We provided free public transport tickets to all registered participants.

Catering

We pioneered a new ‘build-your-own-lunch’ approach to reduce food and paper waste.

We selected a catering partner who focused on sustainable and local products. The food recovered over the Congress days — approximately 750 kg, including first and second courses, fruit, and desserts — was delivered to the soup kitchen of Opera Messa della Carità in Milan, which provides meals to 160 people living in poverty every day. 

Lanyards

We introduced lanyards made of polyester fiber from recycled PET bottles. These were made in a factory where 80% of the power came from European solar panels.

Venue

We selected a convention center that was powered by renewable energy and that used specific bins to encourage waste separation and recycling. 

We also used a recycled carpet which was then transformed into secondary raw materials used for items such as graphic panels, waste bins, furniture components, and more. By recycling the carpet used for Congress, 25.675 kg of CO₂ emissions were avoided. 

Graphics

Forex graphics were collected, broken down and fully recycled to produce more graphics for subsequent events. 

PVC graphics were upcycled by a brand of sustainable tailoring, that uses them to produce reusable shopping bags – after removing all logos/company names. 

EHA2026 activities

Inspired by the success of EHA2025, we’ve raised our ambition for EHA2026.

We’ll provide another sustainability report after the Congress. Watch this space.
