'Carbon passports' would track travel and even restrict how some people take vacation

Ross Bennett-Cook, a visiting lecturer at the University of Westminster, recently said carbon passports will become a reality at some point, according to BelfastLive.

This type of passport would track travelers' carbon footprint.

Fox News Digital reached out to Bennett-Cook for further comment. 

Carbon passports stem from a similar concept that was discussed by the U.K. Parliament in 2008.

The House of Commons debated "personal carbon trading" in an effort to cut down on emissions from certain types of transportation.

It concluded, "Those who need or want to emit more than their allowance have to buy allowances from those who can emit less than their allowance."

In 2024, the U.K. Office for National Statistics found that transportation contributed more to greenhouse gas totals than the electricity sector did.
