Quote:Electric vehicles emit more CO2 than diesel ones, German study shows
Electric vehicles in Germany account for more CO2 emissions than diesel ones, according to a study by German scientists.
When CO2 emissions linked to the production of batteries and the German energy mix - in which coal still plays an important role - are taken into consideration, electric vehicles emit 11% to 28% more than their diesel counterparts, according to the study, presented on Wednesday at the Ifo Institute in Munich.
Mining and processing the lithium, cobalt and manganese used for batteries consume a great deal of energy.
A Tesla Model 3 battery, for example, represents between 11 and 15 tonnes of CO2. Given a lifetime of 10 years and an annual travel distance of 15,000 kilometres, this translates into 73 to 98 grams of CO2 per kilometre, scientists Christoph Buchal, Hans-Dieter Karl and Hans-Werner Sinn noted in their study.
The CO2 given off to produce the electricity that powers such vehicles also needs to be factored in, they say.
When all these factors are considered, each Tesla emits 156 to 180 grams of CO2 per kilometre, which is more than a comparable diesel vehicle produced by the German company Mercedes, for example.The German researchers therefore take issue with the fact that European officials view electric vehicles as zero-emission ones. They note further that the EU target of 59 grams of CO2 per km by 2030 corresponds to a “technically unrealistic” consumption of 2.2 litres of diesel or 2.6 litres of gas per 100 kms.
These new limits pressure German and other European car manufacturers into switching massively to electric vehicles whereas, the researchers feel, it would have been preferable to opt for methane engines, “whose emissions are one-third less than those of diesel motors.”

A constant stream of anti-EV hit pieces crosses our virtual desk, but this one sounded much more serious than the usual anonymous rants. A respected German research institute released a study claiming EVs are dirtier than diesel - exactly what many in the German auto industry were longing to hear.
“Considering Germany’s current energy mix and the amount of energy used in battery production, the CO2 emissions of battery-electric vehicles are, in the best case, slightly higher than those of a diesel engine, and are otherwise much higher,” reads the study from the Munich-based Institute for Economic Research (IFO).
Journalists immediately predicted that automakers would use the new study to lobby policymakers to abandon support for EVs. But, as those who follow the EV scene know, dozens of earlier studies from around the world have come to precisely the opposite conclusion. Could this really be a legitimate scientific study?
Nope. The specious study was promptly and definitively debunked. A few days after it appeared, two of Germany’s major media outlets published detailed analyses that exposed a long list of errors and inaccuracies in the report.
The IFO authors inexplicably calculate CO2 emissions for Model 3 that are 16 percent higher than the official figures published by Germany’s Federal Environmental Agency.
In its calculations of full-lifecycle emissions, the article includes the emissions from electricity generation for EVs, but does not include the emissions generated in producing and transporting the fuel for diesel vehicles.
Unfortunately, as Jonathan Swift (apparently) said, “a lie can travel halfway around the world while the truth is still putting on its shoes.”Yup a 3 person Opinion report with no peer backing … they just want Fossil Fuels around a bit longer, and if that industry is buttering their plate , who can blame them.
