All the large-scale policies you cite are mostly useful for the medium and long term, but counter-productive in the sort-term, as creating new "clean" infrastructures is done using our current, fossil fueled infrastructures.

Personal steps are our main chance at a short term effect, and we need that short term effect. A huge part of greenhouse gas emissions for instance is due to meat. It amounts for more than half of it if you count cattle respiration ! This is something that can be almost exclusively solved by personal involvement, i.e. eating less meat or no meat at all. Likewise for personal transportation and home heating/insulation. With these three things other which people have a lot of control, we cover a large part of greenhouse gas emissions.
