Duke Energy and Dominion Energy threw in the towel Sunday on the Atlantic Coast Pipeline, a proposed 600-mile natural gas line from West Virginia to North Carolina.

Why it matters: It ends one of the highest profile battles over fossil fuel infrastructure in recent years, and its demise is a win for the environmental groups that spent years fighting it.

  • It also underscores hurdles facing big pipelines and other projects, despite White House efforts to speed up approvals and scale back environmental reviews.

Catch up fast: Despite a favorable Supreme Court ruling last month, the project faced ongoing legal and permitting battles.

  • The price tag had reached $8 billion — far above initial estimates — and the project had become "too uncertain to justify investing more shareholder capital," the companies said.
  • The cancelation came the same day that Dominion announced sale of its gas transmission and storage assets to Warren Buffett's Berkshire Hathaway in a $10 billion deal.

Between the lines: Here are a few takeaways from the project's demise...

  • Paperwork matters: Reuters' David Gaffen yesterday re-upped his outlet's October 2019 story, which found that administration efforts to speed up permitting for pipelines had "backfired," because they created new legal vulnerabilities for projects already facing activist litigation.
  • States matter: A note from the research firm ClearView Energy Partners says that some states including Virginia — which is on the pipeline route — push policies that favor renewables. They called the cancellation a sign of "subnational greening" that makes it harder to build projects already facing opposition from environmentalists.
  • The 2020 election matters: This project may be dead, but the outcome of November's election will affect the trajectory of others. The Trump administration backed the project in the courts and politically, while Joe Biden would be less favorable to fossil fuel projects (the campaign did not provide comment on this decision).

BP is providing more info this week about its decades-long plan to diversify away from its dominant fossil fuel business — including expectations for the first few years.

Why it matters: European-based global oil giants are all vowing some kind of decades-long pivot toward more climate-friendly products and deep emissions cuts.

Biden: The next president should decide on Ginsburg’s replacement

Joe Biden is calling for the winner of November's presidential election to select Ruth Bader Ginsburg's replacement on the Supreme Court.

What he's saying: "[L]et me be clear: The voters should pick the president and the president should pick the justice for the Senate to consider," Biden said. "This was the position the Republican Senate took in 2016 when there were almost 10 months to go before the election. That's the position the United States Senate must take today, and the election's only 46 days off.

President Trump will move within days to nominate his third Supreme Court justice in just three-plus short years — and shape the court for literally decades to come, top Republican sources tell Axios.

Driving the news: Senate Majority Leader Mitch McConnell and Senate Republicans are ready to move to confirm Trump's nominee before Election Day, just 46 days away, setting up one of the most consequential periods of our lifetimes, the sources say.
