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.

    Is it? Did we barely measure a drop during covid when nobody was driving at all?

    I’m really asking as I was surprised and saddened when I read about that

      Emissions did fall, actually. Atmospheric levels continued to grow at near the same rate, and there are some posited explanations as to why

      What I’m getting from all this is that any solution will necessarily be long term, as we can’t just stop everything and expect homeostasis to immediately return to the global ecosystem. Regardless of what we do, it will take time for atmospheric levels to start dropping.
