My current job – which I have been doing for almost a year now – makes that for the first time in my life, I have to commute by car. In my previous jobs I was indeed commuting by using public transportation or simply walking.
This current situation is quite embarrassing as I have been dedicated to help protect our civilization from climate change and environmental perils. This is also a financial issue as I spend over 100-120€ on gas each month.
So after reading an article from the French ADEME, I decided to cut my speed on my way back home by 10 kmph, saving fifty euro cents per day, or around ten euros per month.
