Phrase: Carbon footprint due to travel

[Liqichao]

Hi everyone,

I don't understand the sentence below, in particular the words 'carbon footprint due to travel'.

Reducing our travel is also consistent with company's objective to help support our environment by reducing our carbon footprint due to travel.

Thank you for your answers.

I just googled (a synonym for 'Internet search' these days) "carbon footprint"

From Wikipedia (a reference work on the Internet):

"The carbon footprint is a 'measure of the impact that human activities have on the environment in terms of the amount of greenhouse gases produced, measured in units of carbon dioxide'."

Hello Gray,

Hehe, I really appreciate your effort to help .
However, carbon footprint here is a kind of metaphor, I think so, and it has nothing to do with real carbon dioxide.

[Gray]

Yes, it is a metaphor meaning foot prints left behind due to polluting activities. And those foot prints are visible in the form of carbon dioxide. I hope these footprints will take you to the meaning
