Introduction to the Travel Impact Model | webinar

Jun. 24, 2025

Together with Google and the International Council on Clean Transportation (ICCT), we hosted our first webinar to share more with the industry about the Travel Impact Model (TIM) and the growing importance of displaying flight emissions data; both in the leisure and corporate travel markets.

This webinar explores:

  • Why displaying flight emissions matters
  • How the Travel Impact Model (TIM) works
  • How to access and implement the TIM

Key insights

  • Who are Travalyst and why is there a need for sustainability data in the travel industry?
    • As an independent not-for-profit, we mobilise the industry to deliver credible, consistent and compliant sustainability data that is openly accessible for all to use.
    • We know that travellers want to be able to travel more sustainably, but the information they find can be confusing and inconsistent, and many travellers report feeling overwhelmed.
    • The travel and tourism industry contributes 8-10% of global GHG emissions, and to address this, for both travellers and the industry itself, we need reliable sustainability data at scale.
  • What is the TIM, and how does it work?
    • The TIM was developed by Google in collaboration with Travalyst and our partners in order to provide the industry with a free and openly accessible flight emissions tool.
    • It uses inputs like flight schedule data, fuel burn estimates, seat configuration, and load factors to calculate passenger-level CO2e.
    • The data is publicly available via an API, Google Sheets add-on, or full dataset transfer (SFTP).
  • How is the TIM governed?
    • The TIM is overseen by the TIM Advisory Committee (TIM AC), which is chaired by the International Council on Clean Transportation (ICCT).
    • The group is comprised of representatives from across the industry, including academics, NGOs, airlines, and government observers (e.g. FAA, EASA).
    • Through its guiding principle, the TIM AC aims to ensure the model is: accurate, precise, comprehensive, futureproof, transparent, consistent, and accessible.
  • What have we achieved so far with the TIM?
    • Flight emissions estimates have appeared in over 65 billion* searches worldwide.

*Since the airing of this webinar, this number has now increased to over 130 billion searches.
