Getting to net zero emissions means turning off many perfectly functioning power plants before their intended life. It means any emissions that are practically impossible to remove (eg aviation due to the high energy density fuel required) need to be balanced out by negative emissions, which remove existing CO2 from the atmosphere. This inherently (thermodynamically) has a huge cost and little economic benefit (unless you include externalities like environmental effects). I suggest reading/watching any recent talk by Kevin Anderson at the Tyndall Institute, and this paper for an overview: http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0081648 http://journals.plos.org/plosone/article?id=10.1371/journal....
