Microsoft is almost doubling its internal carbon tax that helps fund the company's sustainability work and is joining a Big Oil-backed group pushing for a federal emissions fee.

The big picture: For a sense of scale, Microsoft said that last year it collected $20 million from the tax to pay for internal carbon neutrality work and fund grantees of its AI for Earth program.

HOUSTON — A carbon tax would cost natural gas export company Tellurian Inc. hundreds of millions of dollars, but the company's founder is still backing the policy.

Driving the news: The Houston-based company has done internal modeling showing projected costs on its operations from a carbon tax, which at roughly $200 million a year would be “significant,” says co-founder Charif Souki. Tellurian announced last week it was donating $2 million to Columbia University’s Center on Global Energy Policy to research a carbon tax and related policies.
