Manage My Carbon Footprint

There are many ways to reduce your impact in the environment during MWC21.


Envhironmental Programme

We are a carbon neutrality programme committed to reducing the impact of our business on the environment, both in our offices and at our events.

How you can minimise your impact on the environment during your participation at MWC?


Our aim is to provide exhibitors and contractors with ideas of how they can minimize their impact on the environment during their participation and plan for environmentally friendly solutions in the preparation of the event.

Check out the Sustainable Project Manager Checklist to get ideas on how to make your participation at MWC Barcelona even more sustainable.

Waste Separation

We strongly encourage exhibitors to separate their waste on their stand into paper waste, packaging and mixed waste for recycling. If you decide to do so, then please check at one of the Exhibitor Service Desks and request separate colored bags at no extra cost.

Exhibitors have the option to separate their waste on their stand into paper waste, packaging and mixed waste for recycling.


Waste separation color code:


Blue bag


Yellow bag

Mixed waste

Black bag


Full bags have to be left in the nearest gangway at the end of the day for separate collection



MWC21 Initiatives

Donation Room


Since 2015, we offer a ‘Donation Room’ to all exhibitors to donate materials from your MWC stand to local socially responsible entities that are making an impact in Barcelona and L’Hospitalet

What materials can you donate?

Any furniture, IT equipment, office material or corporate gifts, as well as stand build materials including glass, wood, plants, that are not needed after the event can be collected by our Donation Room Team.

We go to your stand

We pick up the materials from your stand during the end of build-up or during dismantling

Tell us what you like to donate.
We are happy to hear!

Pre-register any materials you would like to donate by filling in the “Donation Room Form” which can be found in the Forms & Deadlines section or contact the hall managers on-site
