It should be fairly obvious to anyone interested in conserving oil that reducing the number of daily commutes per week would reduce the overall demand for oil. There are about 133 million workers in America. Around 80% of them get to work by driving alone in a car. The average commute covers about 16 miles each way.
Reason #1; the impact a 4 day work week could have on crude oil imports. I'm talking about a reduction (5-10%? and perhaps even more--ED by PG) in the amount of oil we need Monday through Friday simply by rearranging our work week. No wonder this idea was utilized in the 70's.
Reason #2 The 4 Day Work Week would reduce greenhouse gas emissions and other air pollutants.
Reason #4 The 4 Day Work Week would mean less traffic congestion.
Reason #5 The 4 Day Work Week would reduce money spent on new road construction and existing road maintenance.
Reason #6 The 4 Day Work Week would result in a reduction in personal expenses.
