OK I find this surprising because I always assumed (well I was told by others) that manufacturing CO2 was negligible. So very likely, I am already greener than a guy with a Nissan Leaf or Model 3. I drive used cars and only drive small cars with small engines (1L cars). My car has tailpipe emissions of 136g/km CO2, and is 11 years old, bought used a year ago. Add to that an additional 47g/km from fuel cycle and I have 183g/km.

Meanwhile the manufacturing of the average EV releases around 10tons of C02. I am omitting the other emissions from using the car (see the study below for details, it's from the author of the tweet). That means I have to drive 55000km until I even reach that. That's 15 years of driving for me, going by my commute of 5km each way everyday. Neither car would last that long.

I used data from here: https://www.oliver-krischer.eu/wp-content/uploads/2020/08/En... https://www.carbonbrief.org/factcheck-how-electric-vehicles-...
