As world leaders gather at the World Economic Forum in Davos this week, Forbes and Global Citizen have partnered up to unveil a list of the Top 25 Givers between 2014 and 2018.
The new list, compiled by Forbes and announced on Tuesday, has named the biggest philanthropists in America in recent years.
It's been released in conjunction with Global Citizen’s Give While You Live campaign, also announced on Tuesday, which calls for the world’s 2,150 billionaires to join the mission to end extreme poverty by 2030.
We’re urging the world’s billionaires to donate 5% of their wealth each year to the effort to achieve the Global Goals in the next 10 years. Together, these billionaires are worth $10 trillion — which is 30 times the funding needed annually to end extreme poverty ($350 billion).
You can find out all about the Give While You Live campaign, and how you can get involved, here.
The new Forbes list is different, because it ranks the donors based on how much of their money actually reaches the people who need it, as opposed to being pledged to the billionaire’s own charitable foundations.
Private charitable foundations can be a problem, because the money pledged to them will often not be used for years — and the world urgently needs funding to end extreme poverty now.
Warren Buffett takes the top spot on the Forbes list, as the biggest philanthropist of the past five years having given away $14.7 billion dollars (16% of his current net worth). He’s followed by Bill and Melinda Gates, who have given away $9.9 billion (9% of their net worth).
The list also includes how much the philanthropists have given, as a percentage of their net worth. On that ranking, Duty Free Shoppers’ Chuck Feeney comes out way on top, having given away practically all of his fortune on his mission to "die broke."
At the other end of the spectrum, meanwhile, is Facebook co-founder Mark Zuckerberg and his wife Priscilla Chan, and Nike co-founder Phil Knight, both of whom have given away less than 2% of their net worth.
Here’s a brief introduction to the top 10 philanthropists — including the sustainable development issues that they care about most.
1. Warren Buffett
American business magnate Buffett has given away $14.7 billion (16.3% of his current net worth) in the past five years, particularly focusing on health and poverty alleviation — channelling a lot of donations into the Bill & Melinda Gates Foundation.

Some of its final initiatives include efforts at promoting health equity throughout the world, and an initiative to reduce the impact of dementia worldwide.
