Beto O'Rourke's first substantive policy plan is here, a $5 trillion proposal that aims for net-zero carbon emissions in the U.S. by 2050.

• O'Rourke timed the announcement to his first visit to Yosemite National Park, which he called a "religious experience," per the AP.
• "Driving in, there are no words that could express what I was seeing or the way that I was feeling. ... And then to learn about some of the challenges that Yosemite faces ... the composition of what we are seeing around us is changing literally before our eyes."

Why it matters: If plans are priorities, the hope and change candidate of 2020 has climate at the top of his list. (He'll also need to ward off Pete Buttigieg.)

• "It's also a sign that he wants to compete directly for the climate candidate mantle with Sen. Bernie Sanders as well as Washington Gov. Jay Inslee, who has made climate the centerpiece of his long-shot run," Axios' Ben Geman writes.

The pillars of Beto's plan:

1. Taking actions with executive power, including a commitment to stay in the Paris Agreement; toughen rules on power plants, auto mileage standards and methane emissions from oil-and-gas development.
2. He'd ask Congress for "$1.5 trillion in direct federal funding, while seeking to incentivize an additional $3.5 trillion from states, private capital and other sources over 10 years to improve aging infrastructure nationwide and to take 'significant actions to defend communities...'" (NYT)
3. Funded by increasing taxes on corporations and the rich, along with ending incentives for fossil fuel companies.
4. Includes tax incentives that are "limited-duration" and "performance-focused" to speed up deployment of climate-friendly tech.

The bottom line: As the current frontrunner, the ball is now in Joe Biden's court.
