If a ban were introduced on the sale of new petrol and diesel cars, and they were replaced by electric cars, the result would be a great reduction in carbon dioxide emissions. That is the finding of new research from Chalmers University of Technology, Sweden, looking at emissions from the entire life cycle \u2013 from the manufacture of electric cars and batteries to electricity used for operation.<\/ins><\/span><\/p>\n

However, the total effect of a phasing out of fossil-fueled cars will not be felt until the middle of the century \u2013 and how the batteries are manufactured will affect the extent of the benefit.<\/span><\/p>\n

A rapid and mandatory phasing in of electric cars could cause emissions from Swedish passenger cars\u2019 exhausts to approach zero by 2045. The Swedish government has proposed an outright ban on the sale of new fossil fuel cars from the year 2030 \u2013 but that alone will not be enough to achieve Sweden\u2019s climate targets on schedule.<\/span><\/p>\n

\u201cThe lifespan of the cars currently on the roads and those which would be sold before the introduction of such a restriction mean that it would take some time \u2013 around 20 years \u2013 before the full effect becomes visible,\u201d says Johannes Morfeldt, researcher in Physical Resource Theory at Chalmers University of Technology and lead author of the recently published scientific study.<\/span><\/p>\n

To have the desired effect, a ban would either need to be introduced earlier, by the year 2025, or, if the ban is not brought in until 2030, then the use of biofuels in petrol and diesel cars needs to increase significantly before then \u2013 in accordance with the revised Swedish \u201creduction obligation\u201d. The combination of these two measures would have the effect of achieving zero emissions from passenger vehicles and keeping to Sweden\u2019s climate targets.<\/span><\/p>\n

\u201cThe results from our study show that rapid electrification of the Swedish car fleet would reduce life cycle emissions, from 14 million tonnes of carbon dioxide in 2020 to between 3 and 5 million tonnes by the year 2045. The end result in 2045 will depend mainly on the extent to which possible emission reductions in the manufacturing industry are realized,\u201d says Johannes Morfeldt.<\/span><\/p>\n

A transition from petrol and diesel cars to electric cars will mean an increased demand for batteries. Batteries for electric cars are often criticized, not least for the fact that they result in high levels of greenhouse gas emissions during manufacture.<\/span><\/p>\n

\u201cThere are relatively good opportunities to reduce emissions from global battery manufacturing. Our review of the literature on this shows that average emissions from global battery manufacturing could decrease by about two-thirds per kilowatt hour of battery capacity by the year 2045. However, most battery manufacturing takes place overseas, so Swedish decision-makers have more limited opportunities to influence this question,\u201d said Johannes Morfeldt.<\/span><\/p>\n

From a climate perspective, it does not matter where the emissions take place, and the risk with decisions taken at a national level for lowering passenger-vehicle emissions is that they could lead to increased emissions elsewhere \u2013 a phenomenon sometimes termed \u2018carbon leakage\u2019. In this case, the increase in emissions would result from greater demand for batteries, and the risk is thus greater the higher the emissions from battery production.<\/span><\/p>\n

In that case, the Swedish decision would not have as great an effect on reducing the climate impact as desired. The life-cycle emissions would end up in the upper range \u2013 around 5 million tonnes of carbon dioxide instead of around 3 million tonnes. Due to this, there may be reason to regulate emissions in both vehicle and battery production, from a life cycle perspective.<\/span><\/p>\n

\u201cWithin the EU, for example, there is a discussion about setting a common standard for the manufacture of batteries and vehicles \u2013 in a similar way as there is a standard that regulates what may be emitted from exhausts,\u201d said Johannes Morfeldt.<\/span><\/p>\n

But, given Sweden\u2019s low emissions from electricity production, a ban on sales of new fossil-fuel cars would indeed result in a sharp reduction of the total climate impact, regardless of how the manufacturing industry develops.<\/span><\/p>\n

The results of the study are based on Swedish conditions, but the method used by the researchers can be used to obtain corresponding figures for other countries, based on each country\u2019s car fleet and energy system. The year 2045 is highlighted because that is when greenhouse gas emissions within Sweden should reach net zero according to the climate policy goals of the country.<\/span><\/p>\n
