How we livein 2050

Consumption in 2050 is still possible, but on a lower level.

If it is possible to reduce emissions relatively quickly it might be possible to allow for 2050 16000 Mill. t COs (16 Gigatons) (and not 8125 Mill. t CO2), see estimation of Stern/Garbett-Shiels (2007), who hope that they can limit global warming with this figure to 2 degrees Celsius. World population in 2050 is estimated at 9 billion, per capita this is a CO2-equivalent of 1,8 tons each year (9 billion / 16 billion t CO2 - 1 Gigaton is 1 billion t). Often this number is simplified to 2 t CO2-equivalent per capita. This is the same as 5,5 kilogram / 5500 gr per day CO2-eq. In order to estimate what one could do with it, you need to calculate the carbon footprint.

CO2-information on product level tell the following (Product Carbon Footprint ‘PCF’): With 5,5 kg / 5500 g CO2 per day a 53 km drive with a Smart (103 g CO2 per km) or an 18 km drive with a Porsche (297 g CO2 per km) ist possible.

1,9 kg CO2 is one bottle of wine, one kilo curd; one kilo beef is too much, it leads to 13.3 kg CO2-emission, pork meat is at 3.3 kg.

Even if electric cars run with wind energy, car must be smaller and more reliable. The manufacturing of a small car leads to 4.1 tons of CO2, a medium-class car is between 4.9 and 5.4 tons, a big car between 6.3 and 7.2 tons COs. Looking at this form a different perspective this might not be completely impossible. If one saves 1 kg CO as a child 20 years long, (20 * 365 = 7300) you may end up with 2 electric cars (calculated with 9 billion people).
