LONDON — The Guardian, three years removed from a Pulitzer Prize that helped spur the British newspaper’s international expansion, is fully embracing a new moneymaking strategy in the face of industrywide revenue problems: philanthropy.

The company has established a nonprofit venture in the United States, theguardian.org, to focus on tapping philanthropic organizations — or even corporate foundations and think tanks — for financial help to report on issues including human rights and climate change.

Rachel White, the president of theguardian.org, said the nonprofit’s charitable status would make it easier for more organizations and private individuals, who might otherwise feel conflicted about contributing to a for-profit newsroom, to donate.

The unit, which received its tax-exempt status in Oct. 2016, has been setting up partnerships since December. Since then, theguardian.org has secured more than $1 million in funding from the Skoll Foundation, which was set up by Jeff Skoll, the first president of eBay; Humanity United, part of the Omidyar Group founded by the eBay founder Pierre Omidyar; and the Conrad N. Hilton Foundation, the organization set up by the hotel entrepreneur.
