Zero emissions goals are very important, not tomorrow, not next year, not end of decade even. But we can't wait until 20, 30, or 40 years from now to get started on that path. The earth isn't making any new fossil fuels, we have what we have and they will run out in the next generation or two. It is hard for old folks to grasp that fact cause it doesn't affect them.
One of the Republican traits and weaknesses is fearing change. This is very evident in the energy sector.

We're looking at potentially spending many tens of trillions of dollars for benefits that will be worth much less. And there's not a lot the USA can do anyway. We currently account for about 13.5% of world CO2 emissions, down from 55% in 1945 and 23% in 1999. U.S. CO2 emissions have and will continue to fall, in large part because of migration of electric power generation from coal to natural gas. Increasing use of renewables will help, but I'm skeptical we'll be able to produce the storage capacity (batteries) so that solar and wind can provide base load supply. Especially after reading about the International Energy Agency's estimates in the Mills article linked above. Are we really going to increase worldwide mining by 4 to 40 times? And rare earth supply by 50 to 300 fold? And what will be the effect on the environment of doing that? Will countries issue the necessary permits? Well, in the USA, there's about a snow ball's chance in hell of that, so we'll just become more dependent on places like China.
Incremental emissions will come from places like India, Indonesia and Africa. And we don't control them. What are we going to do, tell Indians living in apartment blocks in Mumbai they have to swelter in 110 degree heat because they can't build coal fired power plants and have A/C?
Temperature records were set last year. Global warming from CO2 and methane and the like was just one reason. A strong El Nino event was another. A third was that fuel requirements for shipping have been tightened, to make their emissions cleaner. The result is less particulate matter in the atmosphere, and higher temperatures. And maybe that points towards a solution if the shit actually does hit the fan - geoengineering - measures like spraying sulfur dioxide in the atmosphere.
Biden has picked one of the worst possible way to try to reduce emissions -- pump lots of money into inefficient corporate welfare. Why? Well thankfully, he can't pursue some of the supply side measures favored by his advisors who came over from Elizabeth Warren's camp, like knee-capping the domestic oil and gas industry and banning wells on federal leases, because of legal and political considerations. When the price of gasoline goes up and when people start losing oil field jobs in Pennsylvania he loses votes.
That leaves a carbon tax or possibly carbon credits as perhaps the "best" (or least worst) option. I don't like carbon credits, but a reasonable carbon tax, designed so it doesn't hurt our exports, might be OK. You've got to tax something, and if the politicians would take the money from a carbon tax and use it to reduce the income tax or the national debt, I'd probably be for it. The risk is that they take the money and channel it into something like more corporate welfare for renewables. So maybe that's not a good idea.
