pledge campaign

BAM also launches a multiyear pledge campaign to raise $3 million.

The British royal, who is married to Queen Elizabeth II’s youngest son Prince Edward, joined a roundtable discussion to support the "Menopause Workplace Pledge" campaign with Wellbeing of Women, People magazine reported on Monday.

Together with the investor, the couple launched the Giving Pledge campaign in 2010 - encouraging other rich people to donate the majority of their wealth to good causes.

The Giving Pledge campaign was set up in 2010 by U.S. business tycoon Warren Buffett together with by Microsoft Corp co-founder Bill Gates and his wife Melinda to encourage the world’s super-rich to give away most of their wealth to philanthropic causes.

Indeed, the prime minister has already backed the Big Issue's Future Generation Pledge campaign, after a fashion.
