The Carbon Majors Report took a look at industrial carbon dioxide and methane emissions by fossil fuel producers since 1988, and found that just 100 companies have been the source of more than 70% of the world's greenhouse gas emissions, per the Guardian. About half of those emissions have been produced by just 25 corporations, including ExxonMobil, Shell, BP and Chevron.

The study's goal: To pinpoint "how a relatively small set of fossil fuel producers may hold the key to systemic change on carbon emissions," according to Pedro Faria, the technical director at environmental non-profit CDP.

Why it matters: The companies have played a big role in causing greenhouse emissions, and now they could have a big role in cutting them as alternative energy plays a bigger role.

The Postal Service has urged state election officials to pay first class for mail ballots, which Senate Democratic Leader Chuck Schumer says could nearly triple the cost.

Why it matters: Senate Democrats claim that "it has been the practice of USPS to treat all election mail as First Class mail regardless of the paid class of service."
