These sources have minimal bias and use very few loaded words (wording that attempts to influence an audience by using appeal to emotion or stereotypes). The reporting is factual and usually sourced. These are the most credible media sources. See all Least Biased sources.
Factual Reporting: HIGH
Notes: According to their about page “Columbia Univserity’s Earth Institute blends research in the physical and social sciences, education and practical solutions to help guide the world onto a path toward sustainability. In review, the Earth Institute does occasionally use loaded language to convey the message of sustainability and they do not have a favorable view of President Trump. However, the Earth Institute is an evidence based Pro-Science source. We place them in the least biased category rather than Pro-science because they do have a political opinion that slightly leans left, but due to being factual in reporting and pro-science we rate them Least Biased and HIGH for factual reporting.
