ExxonMobil Corp., the world’s largest publicly traded oil producer, is setting a target of cutting its methane emissions 15% within two years, the company said Wednesday.

Why it matters: It’s the latest sign in how big oil and gas companies are cleaning up their operations under pressure from investors, lawsuits and the public on climate change.

“What we’re announcing is our very, very tangible reductions that we can deliver and they’re ambitious, significant and they’re going to make a significant impact on emission reductions.”
— Sara Ortwein, president of XTO Energy, Exxon’s wholly owned subsidiary producing oil and natural in the U.S.

Gritty details:

  • Exxon has made other recent pronouncements on methane, a potent greenhouse gas that’s the primary component of natural gas. But this week’s news is more specific and tangible compared to the previous ones.
  • Wednesday’s announcement also includes a 25% reduction in flaring, a process by which companies burn excess gas off as carbon dioxide.
  • Exxon’s 15% reduction is less than half of what the Obama administration was proposing to do by 2025. The Trump administration rolled back that effort.

Yes, but: It’s hard to compare Exxon’s goal with that of other big oil and gas companies, such as Shell and BP, because each of them has used different metrics to define their target, and the data isn’t available to create an apples to apples comparison, said Matt Watson, an expert on this topic at the Environmental Defense Fund who works with companies. “Moving forward these companies need to release their emissions data and accounting methodologies so reductions can be independently verified. Transparency is critical to earning public trust,” Watson said.

What’s next: Ortwein said beyond cutting methane emissions, the company is also working to make their other products, such as petroleum-derived plastics, cleaner: “We’re looking even broader than our own operations.”

The cliffhanger could be ... Georgia

It hasn't backed a Democrat for president since 1992, but Georgia's changing demographics may prove pivotal this year — not only to Trump v. Biden, but also to whether Democrats take control of the Senate.

Why it matters: If the fate of the Senate did hinge on Georgia, it might be January before we know the outcome. Meanwhile, voters' understanding of this power in the final days of the election could juice turnout enough to impact presidential results.

Climate change goes mainstream in presidential debate

The most notable part of Thursday’s presidential debate on climate change was the fact it was included as a topic and assumed as a fact.

The big picture: This is the first time in U.S. presidential history that climate change was a featured issue at a debate. It signals how the problem has become part of the fabric of our society. More extreme weather, like the wildfires ravaging Colorado, is pushing the topic to the front-burner.

Finally, a real debate

A more disciplined President Trump held back from the rowdy interruptions at tonight's debate in Nashville, while making some assertions so outlandish that Joe Biden chuckled and even closed his eyes. A Trump campaign adviser told Axios: "He finally listened." 

The result: A real debate.
