OXFORD: Globally, only one in 50 new cars were fully electric in 2020, and one in 14 in the UK. Sounds impressive, but even if all new cars were electric now, it would still take 15 to 20 years to replace the world’s fossil fuel car fleet.
One way to reduce transport emissions relatively quickly, and potentially globally, is to swap cars for cycling, e-biking and walking – active travel, as it’s called. Despite the fact that some walking and cycling happens on top of motorised journeys instead of replacing them, more people switching to active travel would equate to lower carbon emissions from transport on a daily and trip-by-trip basis.We observed around 4,000 people living in London, Antwerp, Barcelona, Vienna, Orebro, Rome and Zurich.
If just one in five urban residents permanently changed their travel behaviour in this way over the next few years, we estimate it would cut emissions from all car travel in Europe by about 8 per cent.
Germany electric car and 60% US states marginal emissions = 550g CO2/kWh 550 x 0.2 kWh x km = 110g CO2. petrol car = 120g CO2. car production: +9tons CO2. battery = +5tons CO2. another battery after 10-12 years: +5t CO2. does this really help to reduce CO2?
