Project Drawdown has characterized a set of 93 technologies and practices that together can reduce concentrations of greenhouse gases in the atmosphere. It’s a gigantic project with a lot of data and analyses.
In the linked video, the author goes through the measures to find which one is the most cost effective in terms of ratio of rCO2 reduction and economic cost
The maybe surprising result is that building bike infrastructure to shift a not even big percentage of travels from cars to bicycles or ebikes, is very cheap and has a huge effect on emissions.
The premise is that all solutions should be implemented to have a significant effect, but some are easier done than other.

The data takes that into account. It’s not just about what individuals can do, it’s about all possible solutions and their cost/benefit analysis. Obviously it’s not going to have “stop operations of the small group of companies responsible for 80% of ghg emissions” because that’s not a solution—we’re less likely to cease needing them than we arw to replace them or replace them with more companies that do less individually but the same amout overall—but it will list things like “replace x infrastructure within y industry” and the cost associated with it and how much CO2 equivalent it offsets over time.
