In page Niskanen Center:

"

Funding for the center includes donors who seek to counter libertarian-conservative hostility to measures against global warming.[citation needed] North Carolina businessman Jay Faison, a Republican donor, made an early contribution to the Niskanen Center to spur public climate education[4] but has ceased all ties to the organization in recent years.[citation needed] Other donors include the Open Philanthropy Project, which supports the center's work to expand legal immigration,[5] the Linden Trust for Conservation, which provided the Niskanen Center with a grant "to develop and analyze a potential economy-wide carbon tax",[6] and the Hewlett Foundation, which provided the Center with a $400,000 operations grant.[7]
