Good morning. The Trump administration is planning this week to repeal the Obama-era scientific finding that serves as the legal basis for federal greenhouse-gas regulation, according to U.S. officials, in the most far-reaching rollback of U.S. climate policy to date.

• The original finding: The reversal targets the 2009 “endangerment finding,” which concluded that six greenhouse gases pose a threat to public health and welfare. The finding provided the legal underpinning for the Environmental Protection Agency’s climate rules, which limited emissions from power plants and tightened fuel-economy standards for vehicles under the Clean Air Act.
   
• What the new rule does: The final rule, set to be made public later this week, removes the regulatory requirements to measure, report, certify and comply with federal greenhouse-gas emission standards for motor vehicles, and repeals associated compliance programs, credit provisions and reporting obligations for industries, according to administration officials.
   
• What it won’t target: It wouldn’t apply to rules governing emissions from power plants and other stationary sources such as oil-and-gas facilities, the officials said. But repealing the finding could open up the door to rolling back regulations that affect those facilities.
   
• Industry impact: The move is likely to be seen as a victory for the fossil-fuel industry, which for years has pushed back against federal climate regulations. The decision to repeal the endangerment finding might also create fresh uncertainty for companies with global operations, which could find themselves caught between lower environmental standards at home and a higher baseline for emissions rules abroad. A void at the federal level might prompt states to implement their own regulations, and create new legal exposure for companies.

U.S. files Cfius suit to force Chinese divestiture.

The Trump administration has sued in federal court to enforce a national security order requiring a Chinese technology company to sell a California-based subsidiary, a legal first, reports Risk Journal’s Richard Vanderford.

The Justice Department said Tuesday it filed an action in federal court in Washington, D.C. aimed at forcing Beijing-based Suirui Group to sell off Jupiter Systems, a maker of video-wall technology.

Background: President Trump in July ordered Suirui, which owns Hayward, Calif.-based Jupiter through a Hong Kong-based unit, to divest its interest in the company. Trump made his order on the recommendation of the Committee on Foreign Investment in the United States, which reviews mergers for national security concerns.

A bitcoin blunder for the ages: $40 billion accidentally given away.

The hundreds of prize payouts were mostly just a few bucks each, part of a promotional campaign by a South Korean cryptocurrency exchange. The total reward pot: 620,000 Korean won, or about $425.

Then came a colossal mistake. A staffer for Bithumb, South Korea’s No. 2 crypto exchange, didn’t distribute 620,000 Korean won. Rather, the prizes, due to an input error, emerged in a different currency: 620,000 bitcoins, valued at more than $40 billion.

Impact: The company has since said it has reversed the transactions or had recipients voluntarily return more than 99% of the misdistributed bitcoins. The debacle has landed Bithumb—a trusted name in one of the world’s most active retail crypto markets—in a self-inflicted crisis, with lawmakers calling for tighter laws.

U.S. weighs seizing tankers carrying Iranian oil to pressure Tehran.

Trump administration officials have discussed whether to seize additional tankers involved in transporting Iranian oil but have held off, concerned about Tehran’s near-certain retaliation and the impact on global oil markets, U.S. officials said.

The U.S. has seized several ships that have carried Iranian oil as part of its two-month-old blockade of sanctioned tankers serving Venezuela. The tankers, which make up the so-called shadow fleet, help transport illicit oil from numerous sanctioned countries to China and other buyers.

Canada’s Carney tries to resolve Trump demands over new bridge.

Prime Minister Mark Carney said Canada and the Trump administration would work to resolve a dispute over a new bridge connecting the two countries, a sign of how the U.S. leader’s frequent threats might be losing their bite with some of his foreign counterparts.

Ongoing tension: The fight over the soon-to-be-opened Gordie Howe International Bridge was the third economic threat President Trump has lobbed against Canada in the span of a month, after Carney struck a limited trade pact with China and delivered a speech at Davos calling on smaller powers to fight economic coercion.
