The debate over the environmental impact of electric vehicles (EVs) versus internal combustion engine (ICE) vehicles has been ongoing for years. While some argue that EVs are no cleaner than ICE vehicles due to the fossil fuels used to manufacture and charge them, numerous studies have shown that EVs have lower lifecycle emissions than legacy vehicles. A new study from the International Council on Clean Transportation (ICCT) adds to this literature by comparing the lifecycle greenhouse gas (GHG) emissions of electric, hydrogen, natural gas and diesel trucks and buses in Europe.
The study found that battery-electric trucks are the best option for reducing GHG emissions, with a 63% reduction compared to diesel. This number could reach 84% if the electricity used to charge the vehicles is produced from renewable sources. Fuel cell trucks using hydrogen produced from fossil fuel produce 15% less GHG emissions compared to their diesel counterparts, but this number could reach 85% if the hydrogen is produced with only renewable electricity. Natural gas vehicles have lifecycle emissions ranging from 4% to 18% lower than their diesel counterparts, but methane leakage may undermine these benefits.
Overall, the study found that the greatest climate impact produced by trucks and buses over their lifetimes comes from the use or fuel consumption phase, not from the extraction of raw materials, construction or maintenance. This highlights the importance of transitioning to EVs in order to reduce emissions in the transportation sector. While fuel cell trucks may become a promising option in the future if hydrogen is produced from a 100% renewable energy source, battery-electric models are currently the best option for reducing GHG emissions.
