For many events, participant travel is one of the largest—and hardest to measure—sources of greenhouse gas emissions. Yet organizers often rely on disconnected forms, spreadsheets, and incomplete responses, making it difficult to understand their impact and identify where to improve.
Petit Duc starts with participant travel, helping organizers collect, structure, and interpret the data they need. As the platform evolves, it will bring more event sustainability data and reporting together in one place.
On average, participant travel accounts for 80% of an event’s greenhouse gas emissions—and sometimes more.
Manual tools and incomplete information make measurement and reporting unnecessarily difficult.
Better data helps organizers identify realistic actions for future editions.
Petit Duc brings participant travel data, greenhouse gas calculations, and reporting into one clear workflow. Today, it helps organizers understand one of the largest sources of event emissions. As the platform evolves, it will bring more sustainability data together to support better decisions across the entire event.
Participant journeys are rarely as simple as a single origin and transportation mode. Petit Duc helps you collect real-world travel information, structure complex journeys, calculate related emissions, and make sense of the results.
Collect travel information through an event-specific participant experience.
Account for trips involving multiple transportation modes, stops, locations, or event days.
Consider vehicle occupancy to better represent the impact of shared journeys.
Estimate greenhouse gas emissions associated with the journeys reported by participants.
Understand where participants come from, how they travel, and which journeys contribute most to emissions.
Bring key findings together in clear outputs for internal reporting and external stakeholders.
See where participants come from, how they travel, and which journeys contribute most to your event's greenhouse gas emissions.
Use travel patterns and emission hotspots to improve mobility options, participant communications, and planning for future editions.
Share results with the appropriate context, acknowledge data limitations, and demonstrate progress without overstating your impact.
Turn complex travel data into clear, shareable results for your team, partners, sponsors, and funders.
“We had the opportunity to work with Petit Duc for our 2026 Sustainable Mobility Forum. Using this tool made a real difference, both in reducing our event’s carbon footprint and in raising awareness among our participants. In the end, 85% of them chose a sustainable mode of transportation.”
“Petit Duc turns an often abstract ambition—reducing the footprint of our events—into useful, accessible, action-oriented data. It is exactly what the industry needs: a solution we now use with confidence.”
Petit Duc focuses today on participant travel, one of the most significant and difficult sources of event emissions to measure. The platform is gradually expanding to bring more sustainability data and reporting together in one place.
