Chris Sacca was one of the past decade's most successful venture capitalists, with a run that included early bets in such companies as Instagram, Twitter and Uber. Then, in 2017, he quit.

Driving the news: Sacca is good at investing, but bad at retiring. He's now running a new firm called Lowercarbon Capital, focused on startups that are developing "technologies to reduce CO2 emissions, remove carbon from the atmosphere, and actively cool the planet."

"Clean tech" remains a dirty word for many venture capitalists, due to the mountains of cash lost on such deals in the late aughts.

  • Sacca argues that the sector today is akin to internet tech in 2005 when Y Combinator launched, in terms of lower startup costs and clearer paths to scale.
  • This is not, he stressed to me yesterday during a CB Insights conference interview, a charity case. Sacca also says he welcomes the investment participation of oil majors like Chevron and ExxonMobil, even though that's blasphemy in some clean-tech investment circles.
  • Portfolio companies include a startup focused on lithium extraction tech, a carbon credits marketplace, and an oyster hatchery in Maine.

Details: Lowercarbon currently is structured as a family office ⁠— Chris' wife Crystal is co-founder ⁠— in the tens of millions of dollars. It hasn't yet accepted outside money save for a few special-purpose vehicles with institutional investors from Sacca's prior funds, but there's a growing possibility that it will do a formal fundraiser.

  • Elsewhere: Climate tech investing is having a big week. Sweden's Pale Blue Dot raised $60 million for a new fund, Prime Impact Fund emerged from stealth with $50 million, and Copenhagen Infrastructure Partners raised a €1.5 billion fund focused on renewable energy infrastructure.

The bottom line: Sacca's participation could prompt others to tip their toes back in, or for the first time, but a stampede is unlikely until the new generation of clean tech companies produces a massive hit.

CO2 capture is growing but still lags badly, IEA says

There's growing momentum behind deploying technology that traps and stores CO2 emissions, but much more investment and stronger policies are needed, the International Energy Agency said in a new report.

Why it matters: The technology is vital to enabling the radical emissions cuts needed through the 2050-2070 timeframe to keep temperature rise in check, the agency said.

Trump departs on final Air Force One flight

President Trump and his family took off on Air Force One at 9 a.m. on Wednesday morning for the final time en route to Florida.

The big picture: Trump's final hours as president were punctuated by his decisions to snub his successor's inauguration and grant pardons to many of his allies who have been swept up in corruption scandals.
