Indirect Emissions from Events and Conferences

This document presents guidance for calculating scope 3 emissions resulting from events (e.g., sporting events, concerts) and conferences (e.g., business meetings, exhibits, conventions). The emissions sources covered include: travel to and from an event, emissions from hotel stays by attendees, and emissions from the event or conference venue. Additional GHG emission sources not addressed in this guidance include refrigeration and air conditioning systems, production and transportation of food and materials, waste disposal, and construction of new facilities. This guidance is intended primarily for use by organizations to account for emissions from events and conferences hosted or sponsored by the organization or attended by a large number of the organization’s employees.
