Paperless Event - Sustainable Conference Guide

How much paper does an average conference produce?

A printed conference pack typically weighs 200-300 g per attendee: agenda, notepad, folder, certificate, sponsor materials, and flyers. At 300 people that is 60-90 kg of paper, much of which is in the bin the same day. Across the whole event the waste is far larger - according to Event Industry News, the industry averages 2 kg of waste per person per day, so a two-day 300-person conference produces roughly 1.2 tons of waste of all kinds.

It is not just an environmental issue. It is operational and cost-related too. Print orders must be locked in 2-3 weeks before the event, and any agenda change after print means reprints or errata sheets. For the organizer, that creates rigidity attendees usually only notice when the program changes.

The shift is simple. Most printed materials can be replaced by one app on the attendee's phone. No installation, no App Store. Read why PWA is the new standard in our article on event apps without the App Store.

What a PWA can replace

The standard EventApp feature set can replace most materials that used to go to print.

Previously printed	EventApp module	What you gain
Program and schedule	Agenda	Real-time changes, no errata
Venue map, room plan	Map / Google Maps	Routes to parking, entrances, rooms
Hotel list	Hotel module	Booking links, contacts
Decks, materials, certificates	Downloads	Available post-event, no email blasts
Satisfaction survey	Surveys	Instant results in the organizer panel
Voting cards	Live polls	Results on screen in seconds
Photo album	Gallery	Photos available immediately, including during the event
Contact form	Contact	Inquiries reach the inbox in real time

These features are available in EventApp as standard - as are attendee login, QR check-in, chat and networking, and additional forms. The organizer configures them in the admin panel, without ordering separate tools for every task. If you need something beyond that, we can adapt the app to the way your event works - adding custom sections, integrations with external systems, and features built for one specific event. We covered the survey side in detail in our article on live polls and surveys.

Why no-install PWA matters for ESG

A PWA runs in the phone's browser. The attendee scans a QR code and opens the app right away. There is no store download, no installation, and no need to prepare separate iOS and Android versions.

• No installation files - native apps often weigh 80-150 MB. For 300 attendees that can mean 24-45 GB of transfer. A PWA loads only the screens people actually use, usually a few MB per session.
• One app for every device - the same link works on phones, tablets, and computers. The organizer does not need to maintain several separate versions.
• Opens with no signal - the app and the check-in QR code are stored on the phone, so they work at the door without internet. Content such as the agenda is fetched from the server.

After the event, attendees are not left with another app taking up space on their phone. They can simply remove the shortcut from the home screen.

Multi-language without reprinting

Printing the agenda in three languages triples the cost and the paper. EventApp's multi-language support lets each attendee choose their interface language from one link. That can include Polish, English, German, and other versions needed for the event. No reprints, no logistics, no risk of a German guest receiving a Polish brochure.

This is especially important for hybrid events, where attendees join from different countries. One app, and everyone sees the content in their own language. We covered this in more detail in our article on the app for onsite and online attendees.

Quantifying the ESG impact

If your company reports ESG metrics, reducing paper and CO₂ can become concrete data for the annual report. For a typical 300-person conference, this can mean:

• Paper: 60-90 kg at 300 attendees, at 200-300 g of pack per person - about 1-1.5 trees (17 trees per ton is the standard figure)
• CO₂: roughly 50-100 kg CO₂e avoided; paper production runs 0.7-1.2 kg CO₂e per kilogram depending on recycled content
• Cost: 8,000-15,000 PLN in direct print savings - the industry average is about 40 PLN per attendee
• Labor: 20-40 hours of print coordination, distribution, and disposal removed

When paper still makes sense

1. Entry badge - a lanyard with name and company is still the fastest ID. Limit print to that single item.
2. Roll-ups and branding - reusable scenography elements stay physical, but they are not single-use flyers.
3. Less digital audiences - for senior groups or attendees without smartphones, keep a 5-10% paper run.

12 things you no longer need to print

1. Conference program
2. Building and room maps
3. Speaker bios
4. Partner hotel list
5. Sponsor handouts
6. Satisfaction survey
7. Voting cards
8. Attendance certificates (PDF to download in the app)
9. Photo album
10. Networking attendee list
11. Organizer contact cards
12. Per-session feedback forms

Each of these can be handled in EventApp. You do not need separate tools for every task.

Need something beyond the standard?

EventApp is not a closed tool with one fixed setup. Every deployment is adapted to the event. If you need an extra feature, for example an ESG report in your company's format or carbon footprint tracking for individual sessions, we can build it on request.

Frequently asked questions

What about attendees without a smartphone?

In a typical business conference 95-99% of attendees carry a smartphone. For the rest we keep a short printed run - usually 5-10% of the previous volume. Still a 90% paper reduction.

Does the app work offline in a hotel with weak Wi-Fi?

Partly. The app itself and the check-in QR code work without internet, so they still work at the door with no signal. The agenda, maps, and materials are fetched from the server and need a connection.

Are the surveys and polls GDPR-compliant?

Consents are collected in the registration form: each clause is stored with its version and the moment it was accepted, so you have a documented basis for processing. The connection to the app is encrypted (HTTPS).

How does pricing compare to print?

EventApp is 3,000 PLN net as a one-time fee, with no subscription. Printed materials for a 300-person conference often cost 8,000-15,000 PLN per event. The app can pay for itself on the first event and be reused for future ones.

How do I document the CO₂ reduction in an ESG report?

You can calculate it from the attendee count: a printed pack is typically 200-300 g of paper per person, and paper production runs 0.7-1.2 kg CO₂e per kilogram. We can prepare the statement in your company's format on request.
