There appears to be signficant research on the time it takes for various green technologies to amortise their manufacturing pollution cost. For example the article below estimates a time period of 6 - 18 months for some electric car models. That seems a little low to me so I would like to review the literature a bit more before making any serious claims. Then obviously the greenness of running the car depends on the source of charging electricity. https://cleantechnica.com/2018/02/19/electric-car-well-to-wheel-emissions-myth/ https://cleantechnica.com/2018/02/19/electric-car-well-to-wh... https://www.scientificamerican.com/article/electric-cars-are-not-necessarily-clean/ https://www.scientificamerican.com/article/electric-cars-are...
