The enterprising royal burnished her green credentials this week with the launch of a brand new eco-magazine she helped establish.
Twenty-three-year-old Charlotte was in Italy for the unveiling of Open Ever.
The magazine - to be given out free during Milan and Paris fashion weeks - features articles on fashion and art from an environmentally-friendly perspective.
Charlotte's interest in the link between fashion and the environment grew after she bonded with campaigning designer Stella McCartney.
The duo met through Charlotte's work at Above magazine, for which Stella also worked as a contributing editor, and they struck up a firm friendship.
Stella is said to have enlightened Charlotte about the way in which the fashion industry harms the ecosystem, and the royal has cited Sir Paul's daughter as an inspiration.
Charlotte, who worked for a time as an intern at The Independent, added that renowned experts would be contributing.
