“I don’t believe we should be living with homelessness in the 21st century,” the Prince of Wales said.

Prince William is taking inspiration from his late mother Princess Diana for his latest charitable cause.

In a trailer for the upcoming ITV1 documentary Prince William: We Can End Homelessness shared on Sunday, Oct. 13, the Prince of Wales, 42, discusses his goal to eliminate homelessness through his Homewards initiative.

“I’ve slowly tried to work out what can I bring to the role and the platform that I have,” Prince William said via voiceover.

“I have taken some inspiration and guidance from what my mother did, particularly with homelessness.”

In another snippet from the trailer, the Prince of Wales chatted with football player Fara Williams, who experienced homelessness for six years, according to the BBC. “You played for England and Chelsea whilst you were homeless,” he said.

“I don’t believe we should be living with homelessness in the 21st century,” Prince William concluded the video, which noted the documentary is “coming soon.”

The documentary follows Homewards in its first year as the program works to demonstrate that it’s possible to end homelessness. Launched by Prince William and The Royal Foundation of The Prince and Princess of Wales, the initiative wants to make homelessness “rare, brief and unrepeated” in the next five years.

Prince Williams’ charitable cause is one that his mother was also passionate about helping, Throughout her lifetime, Princess Diana, who died in August 1997, advocated for causes such as homelessness, cancer and AIDS awareness and prevention.

As a child, Prince William and Prince Harry would visit homeless charities with their mother. Much of her work with those experiencing homelessness took place in England. She was a patron of Centrepoint, the U.K.’s leading youth homelessness charity.
