Google improves credibility of Google Flights emission estimates with ICCT partnership


The International Council on Clean Transportation (ICCT) research shows passengers can reduce per trip CO2 by up to 60 per cent by choosing a lower-emitting itinerary. This is due to various differences including aircraft type, seating configurations, load factors, and routing.

Since 2021, Google have been estimating and sharing air-travel-related greenhouse gas emissions on Google Flights powered by their Travel Impact Model (TIM). These estimates help passengers to make informed decisions around the climate impact of their flight choices, increasing transparency and awareness.

Working to improve the quality and credibility of their estimates, Google is introducing an independent Advisory Committee (AC) to oversee and improve the TIM with the ICCT serving as the Secretariat of this new committee. The AC experts have been selected from key industry stakeholders including airlines, academia, leading academics, government representatives, and civil society.

From this July, the TIM Advisory Committee will regularly meet to refine the model, incorporating the latest scientific knowledge. Through increasing the accuracy of the estimates, passengers can better understand the impact of their flights, empowering people to make more sustainable choices.
