FAQ: How can you measure and reduce an event's carbon footprint?

Calculating an event's carbon footprint helps identify the main sources of emissions and make concrete decisions to reduce them.

Transportation for participants, lodging, and meals: these areas can account for a significant portion of the environmental impact of a seminar or conference.

AppCraft's free carbon simulator helps event organizers estimate these emissions, identify the main sources, and compare potential areas for improvement. The results can also help track CSR commitments and prepare for requests for proposals.

The method involves incorporating the collection of environmental information directly into the participant registration process.

With AppCraft, forms can be used to collect information such as transportation methods, lodging details, and dining preferences. This data feeds into the carbon simulator, which uses emission factors based on data from ADEME.

The organizer can then view the estimated emissions by location and export the results. However, some additional information must be entered manually, depending on the scope of the event.

A carbon footprint assessment is particularly useful when conducted early in the event planning process, as it helps identify the decisions that have the greatest impact.

While travel is the main source of emissions, the organizer can, for example, prioritize destinations accessible by train, encourage carpooling, or arrange group shuttles.

AppCraft allows you to analyze broadcasts by segment so you can focus your efforts on the most relevant actions. The goal is to measure results and then use that information to improve future broadcasts.

The AppCraft simulator focuses on simplifying the collection and analysis of participants' main expenses: travel, lodging, and meals.

Unlike a comprehensive carbon footprint assessment, it does not seek to systematically measure all sources of emissions. Its goal is to enable organizers to easily begin measuring their impact and identify priority actions.

The collected data can be exported to specialized software to perform a more comprehensive environmental analysis.

The AppCraft simulator can help collect the environmental data needed for CSR initiatives and, where applicable, for reporting under the CSRD.

In particular, it allows you to estimate certain emissions associated with participants' travel, lodging, and meals, and then export the results.

However, the simulator alone does not constitute a comprehensive CSRD compliance solution. The requirements depend, in particular, on the company’s size and revenue, as well as the applicable regulatory framework.
