I agree 2C peak is the most likely current situation.

When I skimmed the summary report for policymakers (https://report.ipcc.ch/ar6syr/pdf/IPCC_AR6_SYR_SPM.pdf), on page 23 it seems that we are heading towards a 3.2 degrees increase with current measures.

As far as I understand implemented policies refers to policies that are currently taking effect (comparable to policies and actions in climateactointracker prediction, the difference between the numbers is probably due to difference in modeling). Lots of NDCs and targets are to be implemented later and there are economic and political intensives to implement them at least to some degree. That's where 2C comes from.
Also note in the beginning of 2010s solar was very expensive, right now it's (almost) the cheapest source of energy[2] and the technological problem at this point is battery.
That begin said our problem for switching to renewables isn't only technological, there are political reasons (e.g. China and coal [3]) and also despite solar being cheap for a certain period of time running old infrastructure (e.g. natural gas power plant) still makes economic sense, at least in the short term. but I expect that predictions like [1] become more optimistic in this decade.
As a final note in the past economic growth = more pollution which is simply not the case any more for most of the countries.
