Carbon footprints, reliable indicators, reduction plans: how Paris is testing a new approach for its major events — and what it means for local authorities.
Public Events Under Environmental Pressure
Festivals, sporting competitions, markets, food fairs… Public events are at the heart of a region’s social and economic life. They bring people together, attract visitors, and generate economic activity. But they also have a real carbon footprint — often underestimated, and increasingly scrutinized by citizens, elected officials, and organizers alike.
For local authorities, the question is no longer whether they should take action, but how. Without reliable data, it is impossible to act effectively, highlight efforts already underway, or guide decision-making when selecting which events to host.
This is precisely the challenge the City of Paris decided to address by launching an unprecedented pilot program with Climeet in April 2026.
The April 17 Kick-Off: Building Collective Momentum
On Friday, April 17, 2026, nearly 25 participants gathered at Climate House in Paris for the official launch of the pilot initiative. Around the table were representatives from the Department of Ecological and Climate Transition (DTEC), other City departments (DICOM, DJS, DAE), and above all, the organizers of the five pilot events — enthusiastic and already ready to engage.
The energy in the room was palpable. Because this project is not a top-down constraint: it is a voluntary initiative led by teams determined to go beyond statements of intent.
Five Major Parisian Events in the Pilot Program
Five flagship events from the Paris calendar are participating in this first phase:
- Tribune Concorde — June 3 to 7, 2026
- Longines Paris Eiffel Jumping — June 19 to 21, 2026
- Paris Athletics Meeting (Charléty Stadium) — June 28, 2026
- International Gastronomy Village — September 10 to 13, 2026
- La Parisienne (road race) — September 13, 2026
These events differ greatly in nature, format, and audience — making them an especially valuable testing ground to assess the robustness of the methodology and the comparability of the indicators.
What Climeet Brings in Practical Terms
Climeet is a platform dedicated to measuring and reducing the carbon impact of events. In practical terms, it enables organizers to:
1. Collect Environmental Data in a Standardized Way
Participant transport, energy use, catering, waste, accommodation… Every emission source is accounted for using a rigorous methodology tailored to the specific realities of the events industry.
2. Produce Reliable, Comparable, and Actionable Indicators
No more rough estimates. Climeet generates precise carbon assessments, making it possible to compare editions, track progress over time, and communicate transparently.
3. Identify the Most Relevant Reduction Levers
Not all emission sources have the same impact. The platform helps prioritize actions based on their real effectiveness, ensuring efforts are focused where they matter most.
4. Build a Concrete Transition Plan
Each organizer leaves with a realistic, measurable action plan adapted to their event for future editions.
5. Showcase Existing Efforts
The approach enables organizers — and the local authority hosting them — to document and highlight their environmental commitment to audiences and partners.
A Pilot Embedded in Paris’s Broader Strategy
This project did not emerge in isolation. It builds on two major commitments from the City of Paris:
- The Paris Climate and Biodiversity Plan, which sets ambitious territory-wide emissions reduction targets
- The Charter for Eco-Responsible Event Organizers in Paris, which provides a reference framework for event stakeholders committed to sustainability
With this pilot, the DTEC is taking the next step: moving from commitments to data, and from data to action.
The long-term objective is clear: to equip City departments with reliable environmental indicators to guide decisions on selecting and supporting events hosted in Paris.
What This Changes for Local Authorities
The Paris pilot is an important proof of concept. It demonstrates that even large-scale events of very different types can implement a structured approach to measuring and reducing carbon impact.
For other local authorities, this sends a strong message: low-carbon events are no longer a distant ambition — they are becoming a practical reality. And the sooner action begins, the greater the opportunities for progress.
The benefits for authorities engaging in this approach are numerous:
- Stronger credibility with citizens and partners regarding environmental commitments
- Better decision-making tools for departments responsible for event permits and approvals
- Increased internal expertise on event-related carbon challenges
- Greater recognition of efforts already made by local organizers
- Anticipation of future regulatory requirements and rising public expectations
Taking Action: Where to Start?
The good news is that getting started does not require a complete transformation overnight. The Climeet approach is designed to adapt to the realities of local authorities: their constraints, resources, and timelines.
Whether you want to start with one pilot event, structure a broader strategy across your full events calendar, or simply understand what this means in practice — we would be happy to discuss it.
The City of Paris has taken the first step. Other authorities are following. What about you?
