In 2016, the Mercer family donated about $4 billion to climate change denier organizations. Last year, it spent about $4.4 million financing the same organizations according to MapLight.
The money was donated by the Mercer Family Foundation, led by Rebekah Mercer and her father, who are also credited with assisting Trump to win in 2016. This report follows a recent report by the UN which announced that humans only have about 12-years “to significantly reduce carbon emissions or face a global catastrophe.” The Washington Post stated that nations would need to take "unprecedented" action to cut carbon emissions and avoid such disasters.
Organizations which have benefited from their donations include the Heartland Institute, the CO2 Coalition and the Cato Institute. Their work involves challenging environmental regulations and the scientific consensus on man-made climate change.
The Mercers were among the biggest boosters of Trump’s 2016 presidential campaign. The family was closely aligned with Steve Bannon, the former White House strategist and Trump campaign CEO, and funded his conservative news outlet, Breitbart. The Mercers directed and funded a pro-Trump super PAC. They also owned a stake in Cambridge Analytica, a data firm that worked for the Trump campaign and abruptly shut down after it was revealed that the company had harvested private information from the profiles of tens of millions of Facebook users.
