I'm finally sitting down and reading through Biden's climate plan, and it is really, really similar to Beto's. It was a smart move by Beto to get his climate plan out first, even though it wasn't really done, because it makes it look like everyone else is imitating him. (The exceptions to this are Jay Inslee, who imitates no one, and John Delaney, who's imitating Milton Friedman.)
Some highlights:
"Ensure the U.S. achieves a 100% clean energy economy and reaches net-zero emissions no later than 2050."
