Dear Boomers,

Welcome to the second part of our Boom 2025 Eco Letter. The global journey to Boomland is a sign of the spirit of our beautiful, worldwide community. While we acknowledge that mobility is a significant contributor to global GHG emissions (about 15% of the total, according to the IPCC AR report), this is not a barrier but a shared challenge we embrace.

This letter dives into this and the many regenerative measures we pursue to counterbalance its impact, including efforts in reforestation, biodiversity, education and more.

 

 

WHAT ARE SOME OF OUR REGENERATIVE EFFORTS?

 

Did you know?

More than half of all carbon in the atmosphere (55%) is fixed by marine organisms (blue carbon). Seagrass meadows store an average of 830 kg of carbon per hectare per year – around 30× more than terrestrial forests.

This year, we’re launching a pioneer project in the festival world: protecting seagrass meadows.

We support Ocean Alive and the community around the Sado river (Setúbal, Portugal) — a crucial ecosystem in tackling global warming and biodiversity loss.

This is a groundbreaking project we are proud to develop.

And we didn’t stop here. Since 2010 at Boomland, over 1,500 trees and thousands of shrubs were planted following agroecology and permaculture principles:

• Yearly reforestation campaigns.
   
• A documented intervention in 2017.
   
• A short video showcases how we design ecosystems – please share it.
   
• Between 2023–2025: 207 trees + 343 shrubs/aromatics planted.
   
• ~34 tonnes of organic compost reused for reforestation and care.
   
• Over 3,200 planted units and 86 endemic species introduced.

 

CARBON MOBILITY FOOTPRINT

We've analysed our mobility footprint to understand collective impact. Below are the 2025 results:

BOOM BY BIKE INITIATIVE

The Boom by Bike Initiative was inspired by Joost and Stan, who cycled from Belgium to Boom 2008. It celebrates adventure, community and climate awareness. Thank you Boomcyclists for 17 years of commitment.

Some highlights:

• 106 participants, ~63,000 km cycled – avoiding ~7.6 t CO₂e.
   
• ~2,000 bicycles at Boomland.
   
• 320 repairs at the Bike Village.
   
• 11.2 tonnes CO₂e prevented – equal to 510 trees growing for a year, or removing a car for 2.5 years.

 

 

Part III of the Eco Letter will cover Spaceship Earth, gardens and soil. Social initiatives will follow in the Social Awareness newsletter.

May we honour Boomland with presence and care. Thank you Boomers for using the festival as a catalyst for protecting the Earth.

Errata: Mobility Footprint Analysis
We identified a few inaccuracies in the data shared in the Eco Letter to the Boomers II newsletter. The figures have now been corrected in this text, specifically:

• Visitor Impact: 21,702 t CO₂e (instead of 21,701)
• Artist Impact: 92 t CO₂e (instead of 91)
• Supplier Impact: 0.6% (instead of 0.5%)
• Total Impact: 22,103 t CO₂e (instead of 22,101)

These small adjustments do not affect the overall conclusions of the analysis.
