Free guide: guidelines to event sustainability from Helsinki

Strictly speaking, there are no sustainable events: there’s always residue of some kind. But events can always improve their sustainability. Aimed at organisers interested in sustainable event management and turning goals into actions, Sustainability in Meetings – Helsinki Guidelines is a practical resource from the city ranked #1 in the Global Destination Sustainability Index in 2024–2026.

Heini Etsola has seen a lot of sustainability reports. As Senior Advisor, Congresses at Helsinki Convention Bureau, she knows what organisers are looking for. Ask her for a memorable sustainability related moment and she doesn’t reach for a statistic. She tells you about a lunch.

A few years ago, a large international congress came to Helsinki. Its event manager had an idea: one day’s congress lunch would feature plant-based catering only. The board pushed back hard. International delegates were coming. There had to be meat. At least fish. What if no one touched the plant-based food?

The event manager held firm. The lunch happened. The food was good, the feedback was positive, and no one went hungry. Every edition of the congress has included a vegetarian day ever since, and the congress has calculated the resulting emission reductions.

“It came from one person who wanted to do something,” Etsola says.

Concrete tips for meetings sustainability planning

Every year, congress organisers face the same gap: sustainability is on the agenda, in strategy documents, and in questions from boards and stakeholders – but translating it into the decisions of event planning is another matter entirely.

“You should actually do something concrete instead of just talking about how important sustainability is. You actually have to take action,” says Etsola.

That spirit is exactly what the Sustainability in Meetings – Helsinki Guidelines is built on. This free, 20-page framework for event management is the proof. Developed in Helsinki, it can be used for planning events anywhere.

Sneak peek: Your event sustainability planning checklist

The guide covers six themes, from Travel & Transport all the way to Performance Documentation. Etsola is quick to point out The guide covers six themes, from Travel & Transport all the way to Performance Documentation. Etsola is quick to point out what makes it different from the stack of sustainability reports many organisers have gathering dust.

“It’s really, really practical and easy to follow. You often see a lot of reports and things that are really complicated, written in a very scientific way, that are really overwhelming when you start reading. I think we managed to make it quite easy to understand,” Etsola says.

Each theme comes with concrete actions and ready-to-use checklists:

• Add meal tick boxes to cut waste from no-shows.
• Don’t print the event date on signage – reuse it next year.
• Open a lecture to the public and invite local students.
• Donate leftover materials to a school.

The guide pushes organisers to think beyond the event itself – what does it leave behind? There’s even a link to a free carbon footprint calculator.

The final chapter is refreshingly honest – very Finnish, in other words – tackling transparent sustainability reporting head-on, with a nod to the UN Sustainable Development Goals as a framework for measuring impact. Not every objective needs to be met. What matters is knowing why – and improving with subsequent events.

Why Helsinki for meetings and events

Helsinki, capital of the world’s happiest country for the ninth time, may be one of the most attractive congress and events destinations in Europe.

Number one in the Global Destination Sustainability (GDS) Index (2024–2026), Helsinki’s goal is to reduce GHG emissions by 85% from 1990 levels by 2030 and reaching carbon net-zero by 2040 (Climate work in Helsinki). In 2025, Helsinki was also the first city with over 500,000 residents to achieve the Green Destinations certificate. A compact European city where venues, hotels and the airport are within easy reach – on foot or by public transport.

All major event venues in Helsinki – such as Finlandia Hall, Helsinki Expo and Convention Centre Messukeskus and Helsinki Congress Paasitorni – have an environmental certificate such as ISO 14001 or Nordic Swan (GDS-Index 2026) and commitment to improve sustainability in meetings and events, for example through using renewable energy.

The infrastructure here enables the choice of more sustainable solutions, such as the use of reusable water bottles. They can be filled with tap water, which in Finland is among the cleanest in the world (100 points in World Population Review, 2026).

“Sometimes we Helsinkians take it for granted. It’s just the way things are here,” Etsola says.

The guide was built with outside sustainability expertise alongside Helsinki’s own experience.

“We are not perfect and we don’t know everything. So it was also a learning process for us,” she says.

For organisers navigating ESG reporting for events, it’s a practical starting point rather than another document to file. Because behind every sustainability framework is someone who decided to do something.
