Slushtainability

Some of our decorative elements have been used year after year.

If you’ve been attending Slush for several years, you might not have realized that you’ve been standing next to the same plexiglass curtain installation by Sun Effects multiple times.

Emissions from transport are a significant environmental challenge, and therefore Jylhä Logistics Oy has also invested significantly in sustainable development solutions. The company is committed to promoting carbon neutrality and aims to lead the way as a Finnish family-owned logistics company. Jylhä Logistics has been investing in lower-emission gas trucks since 2019. The trucks run on renewable liquefied biogas (LBG), which reduces greenhouse gas emissions by around 90% compared to traditional fossil fuels.

Environmentally friendly logistics is crucial for companies striving to meet tightened emissions standards, this makes Jylhä Logistics a natural choice as a logistics partner also for creating more sustainable events.

You can get straight from your flight to Slush main event venue with one train in 38 minutes. Several trams, trains and buses will take you through the darkness from city centre to Messukeskus.

Public transportation in Helsinki is easy, efficient, and reliable and we encourage everyone to use it. You can buy tickets and find the best routes from the HSL app.‍

We collaborate with Pure Waste for our merch, as their commitment to sustainability uses 99% less water and produces 50% less CO2 compared to similar products made from virgin materials.

We also collaborate with Imperfect Industries, who carefully inspects, cleans and restores second-hand t-shirts for Slush to be loved again, instead of having to produce new apparel.

We have 35 recycling stations and each has volunteers to help you out with sorting. Thanks to this operation, we didn’t have any mixed waste by our event visitors in 2024. Let’s keep it up, shall we?
We’ve also switched to fiber-based packaging—from cups to lunch boxes and cutlery. All of it is collected separately, ensuring that all fiber materials used at the main event are recycled back into fiber.

We’ve switched to fiber-based cups that will be separately collected for recycling so that the fiber can be used again as raw material for packaging.

In 2025, we’re taking our sustainability efforts closer to home. Finnish nature holds a special place in our hearts, so this year we’re supporting the Finnish Natural Heritage Foundation to permanently protect endangered forests here in Finland—an initiative we call the Slush Forest.

Each year, the Slush Main Event generates around 308 tonnes of CO₂ emissions. To take long-term responsibility for this impact, we’re preserving 51 hectares of Finnish forest, which will capture 133.4 tCO₂e annually. This is almost half of our actual event emissions annually. Next year, our plan is to cover the other half, meaning that from then on we’ll capture all our actual event emissions annually, in perpetuity, even if Slush one day ceases from existence.

The Slush Forest currently consists of three sites across Finland:

• Muhos, Kanasuo—27 hectares, annual forest growth 35 m³
• Ylöjärvi, Isomäki—9 hectares, annual forest growth 40 m³
• Joensuu, Tuupovaara, Mustalampi—15 hectares, annual forest growth 70 m³

Together, these areas form the foundation of the Slush Forest, protecting some of Finland’s most valuable natural heritage for generations to come.
