We're all dead if we don't and we cannot afford to add one tiny extra burden onto that monumental task. Sorry. The alternative is death for us all and no chance of any justice ever.
Of course, but people simply won't. So what do we do?
Easiest way to reduce GHG emissions right there.
I think this is far more reasonable. Want to weigh less? Eat a bit less, move a bit more. OP said eliminate all carbon emissions. That's like starving to lose weight. A good compromise is "emit a little less, plant a few more trees" or something along those lines, which is basically what we're doing.
We already know it won't be enough to avoid consequences, as those are already manifesting, but it's the most realistic path forward by far.
A lot of the money is going to have to be spent in the first world ... first to get the technology down in cost but there are existing technologies that developing countries can use now and it should be in their budgets instead of paying for their oversized army or paying ghost salaries to government workers who are all relatives of the minister. I mean these countries will need to act with a discipline and honesty that they are unaccustomed to. We need to get their populations worked up to demand it. (I am from Zimbabwe which is why this bugs me)
To pretend that some people are going to entirely take care of others is demotivating and wrong. Most of us are going to have to take strain.
We are also going to have to de-emphasise NIMBY and other concerns that aren't absolutely critical that might block our investments in clean energy.

The general trend is clear however and has been for decades.
Look into Bjorn Lomborg. I have no idea how accurate his stuff is, but he is the only one that actually seems to take a pragmatic approach to the problem and looks at the bigger picture
The trend is clear, the world is warming, we know the mechanism, we know the cause and we can calculate at least some of the results and we know they’re bad.
People saying “oh but things are always changing, there used to be an ice age” and things like that, completely ignore the pace of change.
You don’t need to panic but please don’t bury your head in the sand.
