I saw this article on digital maps (i.e., Google Maps) being used to determine the best route for traveling between an origin and destination on land. It is interesting because what we usually use as basis for selecting our routes (assuming we can do so since people taking public transport basically have fewer options due to PUVs having mostly fixed routes) are travel time, travel distance and travel cost. Here is the article discussing the addition of fuel efficiency and emissions to the criteria:

Calma, J. (July 25, 2023) “People are using Google Maps to cut down tailpipe pollution,” The Verge, https://www.theverge.com/2023/7/24/23805652/google-maps-fuel-efficient-routes-transportation-emissions [Last accessed: 7/29/2023]

To quote from the article:

“According to Google’s own analysis, many drivers are taking the path of least pollution in their cars. To calculate the tailpipe emissions that prevented, the company compared how much fuel Maps users likely consumed on the routes they drove to how much fuel they would have burned through had they taken the fastest route without its eco-friendly routing tool. The savings amounted to 1.2 million metric tons of avoided CO2 emissions between October 2021, when Google launched the tool, and December 2022.”

While this seems to be a first foray into the including of eco-friendly items in route choice, these items are already and actually included in many travel planners including those used by people selecting which flights to take. We probably just didn’t notice them before or the information were not explicitly stated or posted. Would this really affect or influence the way we travel like how it is reported in the article? Or do we continue to go with the usual and familiar routes?
