The main initiatives
During the organization of the ChangeNOW Summit editions in 2022, 2023 and 2024, several impactful actions were undertaken in collaboration with ClimateSeed to promote sustainability and reduce the event's carbon footprint.
Social Influence
With careful selection of exhibitors and speakers, consideration of stakeholders, and promotion of cultural and gender diversity.
Inclusivity
With an event focused on solidarity, with free solidarity passes for people in need and youth programs for 300 students in priority education zones.
Reduce waste at source
With eco-designed scenography & stands, and no single-use plastic.
Low-carbon food
With an eco-responsibility charter for on-site restaurateurs (local food, 75% vegetarian meals, etc.).
Circularity
Work with a recycling company to sort through 97.3% of reusable materials and sort through 5 cycles of garbage cans (including compost).
Transport
By choosing a central location in Paris, providing temporary parking for bicycles, encouraging car-sharing and favoring rail over the air in partnership with European rail companies.
Low carbon strategy
By having the carbon footprint audited by ClimateSeed and implementing actions to reduce the impact of the summit year on year.
Labelling
By committing to the EEE eco-event label certification, created by the REEVE eco-event's network, ChangeNOW is the first BtoB event to reach level 2.
Summit Carbon Footprint
In 2023, ClimateSeed was ChangeNow's decarbonization partner.
As part of this collaboration, we present to you the results of the GHG assessment for this edition.
Impact Measurement of the 2023 ChangeNOW Summit
ChangeNOW partnered with ClimateSeed to conduct a comprehensive GHG assessment during their annual summit, for the second year running, which took place from May 25th to May 27th, 2023. The assessment revealed that the total GHG emissions for this event amounted to 1,145 tCO2e.
Carbon accounting categorizes GHG emissions from human activities within defined boundaries, considering time, organization, and function. The GHG Protocol and BEGES are widely used for this, mainly for organizational emissions but also for event-related GHG assessments.
ClimateSeed has built its framework in this guide using these methodologies as a foundation, aligning with their principles for scope, calculations, and categorizations while addressing event-specific data and result presentation requirements.
85% of emissions due to participant transport
ChangeNOW's 2023 Summit carbon footprint amounts to 1 145 tCO₂e. This is equivalent, for example, to 477 round-trip flights Paris / New-York or 2 489 round car trips Paris / Berlin. The results per category are the following.
TOP 3 emitting categories :
1️⃣ Transportation of participants: 976 tCO₂e
2️⃣ Purchase of services: 95 tCO₂e
3️⃣ Raw materials: 27 tCO₂e
Our Methodology
Carbon accounting categorizes GHG emissions resulting from human activities according to defined boundaries, taking into account time, organization, and function.
The GHG Protocol and the BEGES are widely used for this purpose, primarily for emissions related to organizations, but also for GHG assessments related to events.
ClimateSeed has built its framework using BEGES methodology as a reference. By adhering to their principles regarding calculations and categorizations, while considering event-specific data and reporting requirements.
The client's testimonial
2023 Carbon & Biodiversity Contribution
Given the importance of taking drastic action on emissions in line with the IPCC's objectives, ChangeNOW acts in parallel with GHG mitigation at corporate and event levels and supports the GHG carbon reduction projects.

Conserves tropical rainforest in a biodiversity hotspot of the Peruvian Amazon
The project combines forest conservation and sustainable economic development by supporting local farmers in transitioning to sustainable cacao production. It restores degraded land, combats deforestation, and provides sustainable, forest-friendly livelihoods. It addresses the drivers of deforestation by investing in commercially viable cacao agroforestry systems and leveraging climate finance to reward forest monitoring and stewardship.
