That’s the beauty of EV efficiency. For CO2 in grams per km But let’s start at the tailpipe, beginning with a regular internal combustion vehicle. A Volkswagen Golf 1.0 TSI is a frugal car, officially emitting 124g/km of CO2. However, we should also consider the CO2 generated by producing the fuel used by this car. This lengthy process varies in emissions depending on where the oil is produced, starting with getting oil to the refinery, refining it, and transporting it to the pump. The average figure for emissions from fuel production was calculated to be 30% extra on top of tailpipe emissions for petrol/gasoline and 24% for diesel by Auke Hoekstra, a senior advisor in smart mobility at Eindhoven University of Technology. In other words, the “well to wheel” emissions for the Golf are 162g/km of CO2. Not terrible, but a considerable bump on the published figure. Next, let’s do a similar calculation for a battery-electric vehicle (BEV). I’m going to choose the Volkswagen ID.3 with the Pro Performance powertrain (58kWh battery and 204PS motor), because it’s a similarly sized vehicle to the Golf and is essentially the latter’s BEV replacement. The ID.3 Pro Performance has a top WLTP energy consumption rating of 250Wh/mile, or 156Wh/km. Obviously, the vehicle itself emits no CO2, but the electricity used to charge the battery does. On average, a kWh of electricity in the UK produced 233g of CO2e in 2019 during generation. This varies a lot worldwide. The US national grid produced 417g per kWh in 2019, and in China the figure was over 600g per kWh. Australia, with one of the world’s worst polluting national grids, generated 656.4g of CO2 per kWh. Taking these figures into account, this would mean the ID.3’s electricity would have produced 36g/km of CO2 in the UK, up to 103g/km in Australia. So even with one of the most polluting national grids, BEVs really are greener “well to wheel” than fossil fuel. ------ Volkswagen Golf 1.0 TSI has CO2 162g/km of CO2. Volkswagen ID.3 has CO2 103g/km in Australia (1). Toyota Prius Hybrid 2018 (on 15-inch wheels) has 78g/km, based on new WLTP testing (2). UK has nuclear power. References 1.
