Events generate emissions throughout the entire value chain — from travel to and from the event and overnight stays to catering and event logistics. With the atmosfair CO₂ event calculator, you can calculate your event’s emissions comprehensively and transparently. The results highlight the largest sources of emissions and provide the basis for effective climate action measures and the offsetting of unavoidable residual emissions.
Product Description
Conferences, trade shows, customer events, and other gatherings often have a significant climate impact, which can sometimes be difficult for companies to quantify. Reliably calculating CO₂ emissions makes these impacts visible and comparable. The atmosfair CO₂ event calculator enables emissions to be calculated across all key areas of an event. It takes into account, among other things, participants’ travel to and from the event, overnight stays, event venues, catering, materials, and other relevant sources of emissions. Event venues, trade show organizers, event agencies, associations, and other event providers can integrate the calculator into their own websites via an iFrame and make it available to their customers.
The calculator helps users estimate missing data using statistical methods, making it possible to calculate an event’s carbon footprint even when not all activity data is available. The calculation is based on the VDR standard “CO₂ Calculation for Business Travel,” developed by atmosfair in collaboration with the German Travel Management Association (VDR). The methodology is fully documented, ensuring that emissions calculations are transparent, traceable, and reliable. The results highlight the areas that contribute most to an event’s carbon footprint and where reduction measures can be most effective.

Integration into your own website
Venue operators, trade fair organisers, event agencies, associations, and other event providers can integrate the atmosfair CO₂ event calculator into their own websites via an iFrame and make it available to their customers. This gives event organisers easy access to emissions calculations from the planning stage onward. Integration does not require the development of a custom calculation methodology and uses the same transparent, fully documented methodology as the atmosfair CO₂ event calculator. We would be happy to advise you on the technical options and potential applications for this integration.
Benefits for your company
- Making the climate impact of events transparent: The event calculator shows the emissions generated by an event and identifies the areas that contribute most to its carbon footprint. The detailed analysis helps you pinpoint emission sources and develop targeted measures to reduce emissions. For example, you can assess mobility plans, event venues, catering options, and accommodation arrangements in terms of their climate impact.
- Planning sustainable events: The results help companies integrate climate action into event planning from the outset and design future events to generate fewer emissions. The emissions calculation provides a solid foundation for communicating sustainability measures to participants, customers, partners, and other stakeholders.
Why atmosfair?
Actionable results
The results go beyond simply calculating emissions. Companies gain concrete insights into which areas contribute most to their carbon footprint and where emission reduction measures can have the greatest impact. The calculation methodology is fully documented, with all assumptions and calculation steps presented transparently and in a traceable manner.
Comprehensive event analysis
The event calculator takes into account the key sources of emissions associated with an event, enabling a holistic assessment of its climate impact. The methodology is based on the VDR standard and draws on many years of experience in calculating emissions from transportation and events.
Nonprofit and independent
As a nonprofit climate action organization, atmosfair’s focus is on transparency, quality, and effective climate action.
Standards and certifications
The atmosfair CO₂ event calculator is based on the VDR standard “CO₂ Calculation for Business Travel.” The calculation methodology for events is fully documented and publicly accessible. The results are CSRD-compliant and can be incorporated directly into relevant reports.
Pricing
Use of the CO₂ event calculator is free of charge. Costs are incurred only when unavoidable residual emissions are offset through atmosfair’s climate action projects.
