Men and women may be from Mars or Venus – but what are their carbon impacts on Earth?

A study by Banque de France delved into the lifestyles of both sexes to reveal which create the most emissions.

Single men have the largest carbon footprint, the researchers claim – spending an average of 2% on items than a single women, which equates to 16% more greenhouse gas emissions.

Transport and holidays were also the big contributors, with men spending much more on these than women.

Consumption patterns drive carbon footprints, the study stresses – with women more likely to buy less carbon intensive, smaller products; instead of frequently going on long trips.

The researchers state that a better understanding of the environmental impact of different habits can tailor lifestyle changes and improve policies and frameworks.
