Car conversion is more effective way towards net zero than production of new cars. Troleycars would be desirable in future. Biofuel use is rather ridiculous (land use, persistent emission)
Although road vehicles account for around 20% of emissions, it goes into the atmosphere mainly during the day and contributes much locally and regionally to excessive carbon dioxide concentration and temperature rise. Fuel consumption standards are the means used to reduce these emissions. The European Union has established that in the years 2020-2021 the average emission of a passenger car of the produced fleet cannot exceed 95g CO2 / km, which corresponds to 4.1l / 100km for a gasoline vehicle and 3.6l / 100km for a diesel. Due to the continuous increase in the number of cars, this will not help to decrease total emissions and generally has little effect. Only replacing motor vehicles with electric ones that will be charged from the renewable energy grid has the chance to reduce total emissions. The policy objective should be to increase the number of electric cars. Many countries are subsidizing the purchase of electric cars. Any motor vehicle can, however, be converted to electric cheaper than purchase a new one. If it were widespread, it could significantly help reduce the negative impact of road traffic on the climate. |
