Weezevent’s carbon footprint: results and tools to assess the impact of our solutions on your events

Weezevent’s carbon footprint: results and tools to assess the impact of our solutions on your events

In a world where global warming emerges as a pressing issue, the events industry is also concerned. Every event, whatever its size, leaves a carbon footprint, and it is our collective responsibility to understand, measure and reduce this impact.

To this end, we have decided to carry out our carbon audit. This work was carried out alongside Hugues Barbotin, a specialist in events and CSR issues and former Director of the Terres du Son Festival in France.

These 3 figures are particularly useful for calculating the impact of our activities on your events:

  • 37 gCO2e per ticket generated,
  • 18 gCO2e per ticket scanned,
  • 226 gCO2e per activated chip.

     1. Context and key figures for Weezevent in 2022

    The carbon footprint presented in this article concerns Weezevent’s activity in 2022. To put our approach into perspective, we need to understand the scale of our operations that year.

    The 116 employees (permanent, fixed-term and freelancers) included in the calculations for this carbon footprint supported more than 129,000 events and deployed more than 7,000 terminals.

    In terms of ticketing, we issued 13 million tickets and scanned 18 million (the existence of third-party distributors explains the difference).

    This reflects Weezevent’s reach in the events sector and the importance of our commitment to an eco-responsible approach.

    2. Carbon footprint methodology

    Carrying out a carbon footprint requires a systematic approach to ensure the accuracy and relevance of the obtained results.

    Data collection

    There are two main ways of collecting the necessary data: based on monetary flows and based on physical flows.

    • Based on monetary flows: It focuses on the expenditure incurred by the company, each of which is assigned an emission coefficient. This method provides an overview based on the volume of money spent.
    • Based on physical flows: It is based on concrete data, such as the weight of materials used or the exact quantities consumed. Although more complex, this method offers greater precision.

    For our assessment we prioritised calculating physical flows, and we used monetary flows when it was impossible to obtain the exact data we wanted.

    Scope of analysis

    For 2022, we have included our three main activities: ticketing, access control and cashless payment. Each activity has been the subject of an assessment completed with an overall assessment covering all our operations. The staff concerned include all our employees, whether permanent, freelancers or seasonal and covers all the territories in which we operate (France, the United Kingdom, Belgium, Switzerland, Spain and Canada).

    In short, the methodology adopted for our carbon footprint reflects our commitment to providing a transparent, comprehensive and accurate analysis of our environmental impact.

    3. Our goals

    While companies with more than 500 employees, in France, are required by law to carry out a carbon footprint assessment, Weezevent has done so voluntarily. Faced with the reality of climate change, initiating positive change in the events sector is essential.

    We have therefore defined 3 priority areas of impact:

    • Internal practices: We aim to involve all our employees in this approach. We firmly believe that every team member can contribute to improving our practices, whether through everyday actions or broader initiatives.
    • Weezevent solutions: We aim to reduce the carbon footprint of every solution we offer. This means rethinking and optimising our processes to minimise the resulting emissions while maintaining the quality and efficiency event organisers expect.
    • Events sector: We want to positively impact the industry by sharing our knowledge, tools and best practices.

    “In 2022, we supported 15,000 event organisers. Even a small positive impact on each of them would translate into a significant impact.” Grégor Einis

    4. Impact per unit of our activities

    Our carbon footprint enables us to reflect the impact per unit of our activities:

    • 37 gCO2e per ticket sent,
    • 18 gCO2e per ticket scanned,
    • 226 gCO2e per activated chip.

    These figures are essential for event organisers, as they can evaluate the carbon impact of Weezevent on their own event by multiplying their volume of activity by these impacts per unit.

    Here are a few comparisons to help you get your bearings:

    5. Weezevent’s detailed carbon footprint

    In total, Weezevent generated 2,041 tCO2e over the year. Considering the number of employees, this represents 17.6 tCO2e/employee.

    Carbon footprint

    The breakdown by activity shows that the cashless activity is the most significant contributor, with 61% of emissions, followed by ticketing at 23% and access control at 16%. This distribution is roughly equal to the breakdown of activities in our sales.

    To put these figures into perspective, our carbon footprint is equivalent to the annual carbon footprint of 200 people (data from France).

    Find out which items emit the most CO2 for each activity:

    • For ticketing: 23% comes from e-mails, 13% from data storage and 10% from browsing event organisers’ websites.
    • For access control: 23% is attributed to infrastructure and telecommunications (the connection needed to deploy terminals), 15% to e-mails, 13% to manufacturing and 5% to equipment end of life.
    • For cashless: 18% comes from infrastructure and telecommunications (the connections needed to deploy terminals), 8% from data management, 8% from banking and 18% from transport.
